Damien George e292296d52 py/objexcept: Remove optional TimeoutError exception.
TimeoutError was added back in 077812b2ab for
the cc3200 port. In f522849a4d the cc3200
port enabled use of it in the socket module aliased to socket.timeout.  So
it was never added to the builtins.  Then it was replaced by
OSError(ETIMEDOUT) in 047af9b10b.

The esp32 port enables this exception, since the very beginning of that
port, but it could never be accessed because it's not in builtins.

It's being removed: 1) to not encourage its use; 2) because there are a lot
of other OSError subclasses which are not defined at all, and having
TimeoutError is a bit inconsistent.

Note that ports can add anything to the builtins via MICROPY_PORT_BUILTINS.
And they can also define their own exceptions using the
MP_DEFINE_EXCEPTION() macro.

Jim Mussared 1921224272 extmod/modubinascii: Make code private and module self-contained.
This commit makes all functions and function wrappers in modubinascii.c
STATIC and conditional on the MICROPY_PY_UBINASCII setting, which will
exclude the file from qstr/ compressed-string searching when ubinascii is
not enabled.  The now-unused modubinascii.h header file is also removed.

The cc3200 port is updated accordingly to use this module in its entirety
instead of providing its own top-level definition of ubinascii.

This was originally like this because the cc3200 port has its own ubinascii
module which referenced these methods.  The plan appeared to be that the
API might diverge (e.g. hardware crc), but this should be done similar to
I2C/SPI via a port-specific handler, rather than the port having its own
definition of the module.  Having a centralised module definition also
enforces consistency of the API among ports.

Damien George 312c699491 esp32: Change from FAT to littlefs v2 as default filesystem.
This commit changes the default filesystem type for esp32 to littlefs v2.
This port already enables both VfsFat and VfsLfs2, so either can be used
for the filesystem, and existing systems that use FAT will still work.

Damien George e0905e85a7 esp8266: Change from FAT to littlefs v2 as default filesystem.
This commit changes the esp8266 boards to use littlefs v2 as the
filesystem, rather than FAT.  Since the esp8266 doesn't expose the
filesystem to the PC over USB there's no strong reason to keep it as FAT.
Littlefs is smaller in code size, is more efficient in use of flash to
store data, is resilient over power failure, and using it saves about 4k of
heap RAM, which can now be used for other things.

This is a backwards incompatible change because all existing esp8266 boards
will need to update their filesystem after installing new firmware (eg
backup old files, install firmware, restore files to new filesystem).

As part of this commit the memory layout of the default board (GENERIC) has
changed.  It now allocates all 1M of memory-mapped flash to the firmware,
so the filesystem area starts at the 2M point.  This is done to allow more
frozen bytecode to be stored in the 1M of memory-mapped flash.  This
requires an esp8266 module with 2M or more of flash to work, so a new board
called GENERIC_1M is added which has the old memory-mapping (but still
changed to use littlefs for the filesystem).

In summary there are now 3 esp8266 board definitions:
- GENERIC_512K: for 512k modules, doesn't have a filesystem.
- GENERIC_1M: for 1M modules, 572k for firmware+frozen code, 396k for
  filesystem (littlefs).
- GENERIC: for 2M (or greater) modules, 968k for firmware+frozen code,
  1M+ for filesystem (littlefs), FAT driver also included in firmware for
  use on, eg, external SD cards.

Damien George 8fff0b0acd unix/mpthreadport: Ensure enough thread stack to detect overflow.
Following up to 5e6cee07ab, some systems (eg
FreeBSD 12.0 64-bit) will crash if the stack-overflow margin is too small.
It seems the margin of 8192 bytes (or thereabouts) is always needed.  This
commit adds this much margin if the requested stack size is too small.

Fixes issue #5824.

David Lechner a2110bd3fc all: Fix implicit casts of float/double, and signed comparison.
These were found by buiding the unix coverage variant on macOS (so clang
compiler).  Mostly, these are fixing implicit cast of float/double to

good measure.

David Lechner 9418611c8a unix: Implement PEP 475 to retry syscalls failing with EINTR.
https://www.python.org/dev/peps/pep-0475/

This implements something similar to PEP 475 on the unix port, and for the
VfsPosix class.

There are a few differences from the CPython implementation:
- Since we call mp_handle_pending() between any ENITR's, additional
  functions could be called if MICROPY_ENABLE_SCHEDULER is enabled, not
  just signal handlers.
- CPython only handles signal on the main thread, so other threads will
  raise InterruptedError instead of retrying.  On MicroPython,
  mp_handle_pending() will currently raise exceptions on any thread.

A new macro MP_HAL_RETRY_SYSCALL is introduced to reduce duplicated code
and ensure that all instances behave the same.  This will also allow other
ports that use POSIX-like system calls (and use, eg, VfsPosix) to provide
their own implementation if needed.

David Lechner 5e6cee07ab unix/mpthreadport: Fix crash when thread stack size <= 8k.
The stack size adjustment for detecting stack overflow in threads was not
taking into account that the requested stack size could be <= 8k, in which
case the subtraction would overflow.  This is fixed in this commit by
ensuring that the adjustment can't be more than the available size.

This fixes the test tests/thread/thread_stacksize1.py which sometimes
crashes with a segmentation fault because of an uncaught NLR jump, which is
a "maximum recursion depth exceeded" exception.

David Lechner 100012bec6 windows: Remove custom definition of MP_PLAT_PRINT_STRN.
This removes the port-specific definition of MP_PLAT_PRINT_STRN on the
windows port, so that the default mp_hal_stdout_tx_strn_cooked() is always
used.  This fixes releasing the GIL during the call to write() (this was
missed in bc3499f010).

Also, mp_hal_dupterm_tx_strn() was defined but never used anywhere so it is
safe to delete it.

David Lechner b1066a9f96 unix: Remove custom definition of MP_PLAT_PRINT_STRN.
This removes the port-specific definition of MP_PLAT_PRINT_STRN on the unix
port.  Since fee7e5617f this is no longer a
single function call so we are not really optimising anything over using
the default definition of MP_PLAT_PRINT_STRN which calls
mp_hal_stdout_tx_strn_cooked().

Damien George 40255aff23 stm32/mboot: Remove unnecessary test for led being 1 in led_state.
The "led" argument is always a pointer to the GPIO port, or'd with the pin
that the LED is on, so testing that it is "1" is unnecessary.  The type of
"led" is also changed to uint32_t so it can properly hold a 32-bit pointer.

Andrew Leech 9dd470b768 stm32/mboot: Update LED0 state from systick handler.
Updating the LED0 state from systick handler ensures LED0 is always
consistent with its flash rate regardless of other processing going on in
either interrupts or main.  This improves the visible stability of the
bootloader, rather than LED0 flashing somewhat randomly at times.

This commit also changes the LED0 flash rate depending on the current state
of DFU, giving slightly more visual feedback on what the device is doing.

Jim Mussared f46782dde9 mimxrt: Add new, minimal port to NXP i.MX RT series CPUs.
This is an extremely minimal port to the NXP i.MX RT, in the style of the
SAMD port  It's largely based on the TinyUSB mimxrt implementation, using
the NXP SDK.  It currently supports the Teensy 4.0 board with a REPL over
the USB-VCP interface.

This commit also adds the NXP SDK submodule (also from TinyUSB) to
lib/nxp_driver.

Note: if you already have the tinyusb submodule initialized recursively you
will need to run the following as the tinyusb sub-submodules have been
rearranged (upstream):

    git submodule deinit lib/tinyusb

David Lechner 3bd2ae1a36 unix/mpthreadport: Use SIGRTMIN+5 instead of SIGUSR1 for thread-GC.
This changes the signal used to trigger garbage collection from SIGUSR1 to
SIGRTMIN + 5.  SIGUSR1 is quite common compared to SIGRTMIN (measured by
google search results) and is more likely to conflict with libraries that
may use the same signal.

POSIX specifies that there are at least 8 real-time signal so 5 was chosen
as a "random" number to further avoid potential conflict with libraries
that may use SIGRTMIN or SIGRTMAX.

Also, if we ever have a `usignal` module, it would be nice to leave SIGUSR1
and SIGUSR2 free for user programs.

Damien George ac8383a95d nrf: Use MICROPY_HW_ENABLE_RNG instead of MICROPY_PY_RANDOM_HW_RNG.
The "random" module no longer uses the hardware RNG (the extmod version of
this module has a pseudo-random number generator), so the config option
MICROPY_PY_RANDOM_HW_RNG is no longer meaningful.  This commit replaces it
with MICROPY_HW_ENABLE_RNG, which controls whether the hardware RNG is
included in the build.
2020-02-18 12:43:16 +11:00
Damien George 6ad3bb1e12 nrf: Remove custom "random" module and use extmod version instead.
Hardware RNG code is moved to drivers/rng.[ch].
2020-02-18 12:43:16 +11:00
cccc 4f3e5ea934 nrf/drivers/bluetooth: Fix variable initialisation error with older gcc.
Without this change, arm-none-eabi-gcc version 4.9.3 (at least) would give
a "missing braces around initializer" error.
2020-02-16 23:46:27 +11:00
David Lechner 4af79e7694 unix/Makefile: Allow to install all variants of the executable.
The install target is current broken when PROG is used to override the
default executable name.  This fixes it by removing the redundant TARGET
variable and uses PROG directly instead.

The install and uninstall targets are also moved to the common unix
Makefile so that all variants can be installed in the same way.
2020-02-16 23:37:40 +11:00
David Lechner c5f4268c99 unix/variants/standard: Fix role of PREFIX when used to install.
Currently it is not possible to override PREFIX when installing micropython
using the makefile.  It is common practice to be able to run something like
this:

    $ make install PREFIX=/usr DESTDIR=/tmp/staging

This fixes such usage.
2020-02-16 23:35:52 +11:00
Damien George baf11f237b unix/Makefile: Remove old variant targets that are no longer needed.
To eliminate confusion about what targets to use when building.

Damien George ad7213d3c3 py: Add mp_raise_msg_varg helper and use it where appropriate.
This commit adds mp_raise_msg_varg(type, fmt, ...) as a helper for
nlr_raise(mp_obj_new_exception_msg_varg(type, fmt, ...)).  It makes the
C-level API for raising exceptions more consistent, and reduces code size
on most ports:

   bare-arm:   +28 +0.042%
minimal x86:  +100 +0.067%
   unix x64:   -56 -0.011%
unix nanbox:  -300 -0.068%
      stm32:  -204 -0.054% PYBV10
     cc3200:    +0 +0.000%
    esp8266:   -64 -0.010% GENERIC
      esp32:  -104 -0.007% GENERIC
        nrf:  -136 -0.094% pca10040
       samd:    +0 +0.000% ADAFRUIT_ITSYBITSY_M4_EXPRESS
2020-02-13 11:52:40 +11:00
Damien George 97eca38c4f py: Add mp_raise_type helper macro and use it where appropriate.
This provides a more consistent C-level API to raise exceptions, ie moving
away from nlr_raise towards mp_raise_XXX.  It also reduces code size by a
small amount on some ports.

Damien George 5a755ac30a esp32/modsocket: Convert EADDRINUSE error code from lwip return value. 2020-02-11 13:59:09 +11:00
stijn 5f91933e54 windows: Improve default search path.
The default value for MICROPYPATH used in unix/main.c is
"~/.micropython/lib:/usr/lib/micropython" which has 2 problems when used in
the Windows port:
- it has a ':' as path separator but the port uses ';' so the entire string
  is effectively discarded since it gets interpreted as a single path which
  doesn't exist
- /usr/lib/micropython is not a valid path in a standard Windows
  environment

Override the value with a suitable default.
2020-02-11 13:34:35 +11:00
stijn 8b6e6008c7 unix/main: Use OS-dependent path separator when searching path. 2020-02-11 13:33:56 +11:00
Damien George 580fd636c0 nrf/drivers: Use mp_raise_msg where appropriate, and shorten exc msgs.
If the exception doesn't need printf-style formatting then calling
mp_raise_msg is more efficient.  Also shorten exception messages to match
style in core and other ports.
2020-02-11 11:45:14 +11:00
Damien George ce40abcf21 stm32/usbd_cdc_interface: Remove "interrupt_char != -1" check.
It's not needed.  The C integer implicit promotion rules mean that the
uint8_t of the incoming character is promoted to a (signed) int, matching
the type of interrupt_char.  Thus the uint8_t incoming character can never
be equal to -1 (the value of interrupt_char that indicate that interruption
is disabled).
2020-02-07 16:08:37 +11:00
Damien George 046ae80bdf unix, windows: Use mp_keyboard_interrupt instead of custom code.
The mp_keyboard_interrupt() function does exactly what is needed here, and
using it gets ctrl-C working when MICROPY_ENABLE_SCHEDULER is enabled on
these ports (and MICROPY_ASYNC_KBD_INTR is disabled).
2020-02-07 16:08:33 +11:00
Damien George abe2caf6df py/scheduler: Move clearing of kbd traceback to mp_keyboard_interrupt.
This is a more logical place to clear the KeyboardInterrupt traceback,
right before it is set as a pending exception.  The clearing is also
optimised from a function call to a simple store of NULL.
2020-02-07 16:08:31 +11:00
Damien George f4641b2378 esp32/uart: Use core-provided mp_keyboard_interrupt, placed in IRAM. 2020-02-07 16:08:31 +11:00
Damien George 8d0421c3cf esp8266: Put mp_keyboard_interrupt in IRAM.
It was originally in IRAM due to the linker script specification, but
since the function moved from lib/utils/interrupt_char.c to py/scheduler.c
it needs to be put back in IRAM.
2020-02-07 16:08:31 +11:00
Damien George eaf30c516a tests/unix: Add coverage tests for kbd-intr and scheduler. 2020-02-07 16:08:29 +11:00
Damien George 9efb36bfa6 py/scheduler: Move mp_keyboard_interrupt from lib/utils to py core.
This function is tightly coupled to the state and behaviour of the
scheduler, and is a core part of the runtime: to schedule a pending
exception.  So move it there.
2020-02-07 16:08:26 +11:00
Damien George 5a91cd9ff3 lib/utils/pyexec: Handle pending exceptions after disabling kbd intrs.
Pending exceptions would otherwise be handled later on where there may not
be an NLR handler in place.

A similar fix is also made to the unix port's REPL handler.

Fixes issues #4921 and #5488.
2020-02-07 16:08:26 +11:00
Damien George 98a3911c43 py/scheduler: Add "raise_exc" argument to mp_handle_pending.
Previous behaviour is when this argument is set to "true", in which case
the function will raise any pending exception.  Setting it to "false" will
cancel any pending exception.
2020-02-07 16:08:20 +11:00
Maureen Helm 7a5752a748 zephyr: Enable littlefs.
Enables the littlefs (v1 and v2) filesystems in the zephyr port.

Example usage with the internal flash on the reel_board or the
rv32m1_vega_ri5cy board:

import os
from zephyr import FlashArea
bdev = FlashArea(FlashArea.STORAGE, 4096)
os.VfsLfs2.mkfs(bdev)
os.mount(bdev, '/flash')
with open('/flash/hello.txt','w') as f:
    f.write('Hello world')
print(open('/flash/hello.txt').read())

Things get a little trickier with the frdm_k64f due to the micropython
application spilling into the default flash storage partition defined
for this board. The zephyr build system doesn't enforce the flash
partitioning when mcuboot is not enabled (which it is not for
micropython). For now we can demonstrate that the littlefs filesystem
works on frdm_k64f by constructing the FlashArea block device on the
mcuboot scratch partition instead of the storage partition. Do this by
replacing the FlashArea.STORAGE constant above with the value 4.
2020-02-07 11:24:06 +11:00
Maureen Helm 86a66960f9 zephyr: Implement block device protocol via zephyr flash map api.
Introduces a new zephyr.FlashArea class that uses the zephyr flash map
api to implement the uos.AbstractBlockDev protocol. The flash driver is
enabled on the frdm_k64f board, reel_board, and rv32m1_vega_ri5cy board.

The standard and extended block device protocols are both supported,
therefore this class can be used with file systems like littlefs which
require the extended interface.
2020-02-07 11:24:06 +11:00
Maureen Helm 2d7ec8e704 zephyr: Enable fatfs.
Enables the fatfs filesystem in the zephyr port.

Example usage with an SD card on the mimxrt1050_evk board:

import zephyr, os
bdev = zephyr.DiskAccess('SDHC')
os.VfsFat.mkfs(bdev)
os.mount(bdev, '/sd')
with open('/sd/hello.txt','w') as f:
    f.write('Hello world')
print(open('/sd/hello.txt').read())
2020-02-07 11:24:06 +11:00
Maureen Helm a0440b01ea zephyr: Enable virtual file system and uos module.
Enables the virtual file system and uos module in the zephyr port.
No concrete file system implementations are enabled yet.
2020-02-07 11:24:06 +11:00
Maureen Helm cc19cf2549 zephyr: Implement block device protocol via zephyr disk access api.
Introduces a new zephyr.DiskAccess class that uses the zephyr disk
access api to implement the uos.AbstractBlockDev protocol. This can be
used with any type of zephyr disk access driver, which currently
includes SDHC, RAM, and FLASH implementations. The SDHC driver is
enabled on the mimxrt1050_evk board.

Only the standard block device protocol (without the offset parameter)
can be supported with the zephyr disk access api, therefore this class
cannot be used with file systems like littlefs which require the
extended interface. In the future it may be possible to implement the
extended interface in a new class using the zephyr flash api.

2020-02-04 18:06:14 +11:00
David Lechner f1b6e6bb15 unix/modos: Implement putenv and unsetenv to complement getenv.
CPython also has os.environ, which should be used instead of os.getenv()
due to caching in the os.environ mapping.  But for MicroPython it makes
sense to only implement the basic underlying methods, ie getenv/putenv/
unsetenv.
2020-02-04 17:54:31 +11:00
David Lechner 83439e38fc unix/main: Add command-line -h option for printing help text.
This adds a -h option to print the usage help text and adds a new, shorter
error message that is printed when invalid arguments are given.  This
behaviour follows CPython (and other tools) more closely.
2020-02-04 17:54:31 +11:00
David Lechner 5a63bc5a44 unix/main: Add #if guard around -v option usage and document -i/-m opts.
This commit modifies the usage() function to only print the -v option help
text when MICROPY_DEBUG_PRINTERS is enabled.  The -v option requires this
build option to be enabled for it to have any effect.

The usage text is also modified to show the -i and -m options, and also
show that running a command, module or file are mutually exclusive.
2020-02-04 17:53:35 +11:00
David Lechner 122baa6787 unix/main: Add support for MICROPYINSPECT environment variable.
This adds support for a MICROPYINSPECT environment variable that works
exactly like PYTHONINSPECT; per CPython docs:

    If this is set to a non-empty string it is equivalent to specifying the
    -i option.

    This variable can also be modified by Python code using os.environ to
    force inspect mode on program termination.
2020-02-04 17:52:58 +11:00
Maureen Helm bc3ce86a5a zephyr: Remove reference to syscall_macros_h_target.
Zephyr removed the build target syscall_macros_h_target in commit
f4adf107f31674eb20881531900ff092cc40c07f.  Removes reference from
MicroPython to fix build errors in the zephyr port.

This change is not compatible with zephyr v2.1 or earlier.  It will be
compatible with Zephyr v2.2 when released.
2020-02-04 17:10:24 +11:00
Maureen Helm a7663b862e zephyr: Replace deprecated time conversion macro.
The SYS_CLOCK_HW_CYCLES_TO_NS macro was deprecated in zephyr commit
8892406c1de21bd5de5877f39099e3663a5f3af1.  This commit updates MicroPython
to use the new k_cyc_to_ns_floor64 api and fix build warnings in the zephyr
port.

This change is compatible with Zephyr v2.1 and later.
2020-02-04 17:09:59 +11:00
Maureen Helm c25e12d0dd zephyr: Update include paths for Zephyr v2.0.
Zephyr restructured its includes in v2.0 and removed compatibility shims
after two releases in commit 1342dadc365ee22199e51779185899ddf7478686.
Updates include paths in MicroPython accordingly to fix build errors in
the zephyr port.

These changes are compatible with Zephyr v2.0 and later.
2020-02-04 17:09:19 +11:00
David Lechner 4ab8bee82f unix/main: Print usage and NLR errors to stderr instead of stdout.
When stdout is redirected it is useful to have errors printed to stderr
instead of being redirected.

mp_stderr_print() can't be used in these two instances since the
MicroPython runtime is not running so we use fprintf(stderr) instead.

Damien George 2c8c2b935e stm32/powerctrl: Improve support for changing system freq on H7 MCUs.
This commit improves pllvalues.py to generate PLL values for H7 MCUs that

Andrew Leech 30501d3f54 drivers, stm32: Support SPI/QSPI flash chips over 16MB.
With a SPI flash that has more than 16MB, 32-bit addressing is required
rather than the standard 24-bit.  This commit adds support for 32-bit
addressing so that the SPI flash commands (read/write/erase) are selected
automatically depending on the size of the address being used at each
operation.
2020-01-30 13:18:38 +11:00
David Lechner b72cb0ca1b py/mpthread.h: Use strong type for mp_thread_set_state() argument.
This modifies the signature of mp_thread_set_state() to use
mp_state_thread_t* instead of void*.  This matches the return type of
mp_thread_get_state(), which returns the same value.

`struct _mp_state_thread_t;` had to be moved before
`#include <mpthreadport.h>` since the stm32 port uses it in its
mpthreadport.h file.
2020-01-29 17:10:32 +11:00
Damien George a542c6d7e0 stm32/powerctrl: For F7, allow PLLM!=HSE when setting PLLSAI to 48MHz.
PLLM is shared among all PLL blocks on F7 MCUs, and this calculation to
configure PLLSAI to have 48MHz on the P output previously assumed that PLLM
is equal to HSE (eg PLLM=25 for HSE=25MHz).  This commit relaxes this
assumption to allow other values of PLLM.

David Lechner d89ed3e62b unix/unix_mphal: Add compile check for incompatible GIL+ASYNC_KBD_INTR.
It is not safe to enable MICROPY_ASYNC_KBD_INTR and MICROPY_PY_THREAD_GIL

2020-01-26 23:27:40 +11:00
David Lechner fee7e5617f unix: Release GIL during all system calls.
Addition of GIL EXIT/ENTER pairs are:

- modos: release the GIL during system calls.  CPython does this as well.

- moduselect: release the GIL during the poll() syscall.  This call can be
  blocking, so it is important to allow other threads to run at this time.

- modusocket: release the GIL during system calls.  Many of these calls can
  be blocking, so it is important to allow other threads to run.

- unix_mphal: release the GIL during the read and write syscalls in
  mp_hal_stdin_rx_chr and mp_hal_stdout_tx_strn.  If we don't do this
  threads are blocked when the REPL or the builtin input function are used.

- file, main, mpconfigport.h: release GIL during syscalls in built-in
  functions that could block.
2020-01-26 23:21:29 +11:00
Damien George 96716b46e1 unix/Makefile: Reserve CFLAGS_EXTRA/LDFLAGS_EXTRA for external use.
When CFLAGS_EXTRA/LDFLAGS_EXTRA (or anything) is set on the command line of
a make invocation then it will completely override any setting or appending
of these variables in the makefile(s).  This means builds like the coverage
variant will have their mpconfigvariant.mk settings overridden.  Fix this
by using CFLAGS/LDFLAGS exclusively in the makefile(s), reserving the
CFLAGS_EXTRA/LDFLAGS_EXTRA variables for external command-line use only.

stijn 599371b133 windows: Support word-based move/delete key sequences for REPL.
Translate common Ctrl-Left/Right/Delete/Backspace to the EMACS-style
sequences (i.e. Alt key based) for forward-word, backward-word, forwad-kill

JensDiemer c14ff6194c esp8266/modules: Fix AttributeError in _boot.py if flash not formatted.
Prior to this commit, if the flash filesystem was not formatted then it
would error: "AttributeError: 'FlashBdev' object has no attribute 'mount'".
That is due to it not being able to detect the filesystem on the block
device and just trying to mount the block device directly.

This commit fixes the issue by just catching all exceptions.  Also it's not
needed to try the mount if `flashbdev.bdev` is None.

Yonatan Goldschmidt 853aaa06f2 lib/mp-readline: Add word-based move/delete EMACS key sequences.
This commit adds backward-word, backward-kill-word, forward-word,
forward-kill-word sequences for the REPL, with bindings to Alt+F, Alt+B,
Alt+D and Alt+Backspace respectively.  It is disabled by default and can be
enabled via MICROPY_REPL_EMACS_WORDS_MOVE.

Further enabling MICROPY_REPL_EMACS_EXTRA_WORDS_MOVE adds extra bindings
for these new sequences: Ctrl+Right, Ctrl+Left and Ctrl+W.

The features are enabled on unix micropython-coverage and micropython-dev.

Jim Mussared bd2fff6687 unix: Add build variants, analogous to boards on bare-metal.
Invoking "make" will still build the standard "micropython" executable, but
other variants are now build using, eg, "make VARIANT=minimal".  This
follows how bare-metal ports specify a particular board, and allows running
any make target (eg clean, test) with any variant.

Convenience targets (eg "make coverage") are provided to retain the old
behaviour, at least for now.

See issue #3043.

Damien George bfbd94401d py: Make mp_obj_get_type() return a const ptr to mp_obj_type_t.
Most types are in rodata/ROM, and mp_obj_base_t.type is a constant pointer,
so enforce this const-ness throughout the code base.  If a type ever needs
to be modified (eg a user type) then a simple cast can be used.

Damien George e3187b052f stm32/boards/PYBD: Change RTC asynch prediv from 1 to 4.
This change has the following effects:
- Reduces the resolution of the RTC sub-second counter from 30.52us to
  122.07us.
- Allows RTC.calibration() to now support positive values (as well as
  negative values).
- Reduces VBAT current consumption in standby mode by a small amount.

For general purpose use 122us resolution of the sub-second counter is
good enough, and the benefits of full range calibration and minor reduction
in VBAT consumption are worth the change.

Nicko van Someren 4c93955b7b py/objslice: Add support for indices() method on slice objects.
Instances of the slice class are passed to __getitem__() on objects when
the user indexes them with a slice.  In practice the majority of the time
(other than passing it on untouched) is to work out what the slice means in
the context of an array dimension of a particular length.  Since Python 2.3
there has been a method on the slice class, indices(), that takes a
dimension length and returns the real start, stop and step, accounting for
missing or negative values in the slice spec.  This commit implements such
a indices() method on the slice class.

It is configurable at compile-time via MICROPY_PY_BUILTINS_SLICE_INDICES,
disabled by default, enabled on unix, stm32 and esp32 ports.

This commit also adds new tests for slice indices and for slicing unicode
strings.

Yonatan Goldschmidt 61d2b40ad5 lib/utils/pyexec: Introduce MICROPY_REPL_INFO, wrap debug prints in it.
For the 3 ports that already make use of this feature (stm32, nrf and
teensy) this doesn't make any difference, it just allows to disable it from
now on.

For other ports that use pyexec, this decreases code size because the debug
printing code is dead (it can't be enabled) but the compiler can't deduce
that, so code is still emitted.

The default protection for the BLE ringbuf is to use

This commit refactors and generalises the boot-mount routine on stm32 so

Damien George 799b6d1e0c extmod: Consolidate FAT FS config to MICROPY_VFS_FAT across all ports.
This commit removes the Makefile-level MICROPY_FATFS config and moves the
MICROPY_VFS_FAT config to the Makefile level to replace it.  It also moves
the include of the oofatfs source files in the build from each port to a
central place in extmod/extmod.mk.

For a port to enabled VFS FAT support it should now set MICROPY_VFS_FAT=1
at the level of the Makefile.  This will include the relevant oofatfs files
in the build and set MICROPY_VFS_FAT=1 at the C (preprocessor) level.

This commit adds support for littlefs (v2) on all esp32 boards.

The original FAT filesystem still works and any board with a preexisting
FAT filesystem will still work as normal.  It's possible to switch to
littlefs by reformatting the block device using:

    import uos, flashbdev
    uos.VfsLfs2.mkfs(flashbdev.bdev)

Then when the board reboots (soft or hard) the new littlefs filesystem will
be mounted.  It's possible to switch back to a FAT filesystem by formatting
with uos.VfsFat.mkfs(flashbdev.bdev).

This commit adds an implementation of machine.Timer backed by the soft
timer mechanism.  It allows an arbitrary number of timers with 1ms
resolution, with an associated Python callback.  The Python-level API
matches existing ports that have a soft timer, and is used as:

    from machine import Timer
    t = Timer(freq=10, callback=lambda t:print(t))
    ...
    t = Timer(mode=Timer.ONE_SHOT, period=2000, callback=lambda t:print(t))
    ...
    t.deinit()

Damien George a5d97f1db9 stm32: Add soft timer implementation, using SysTick at 1ms resolution.
This commit adds an implementation of a "software timer" with a 1ms
resolution, using SysTick.  It allows unlimited number of concurrent
timers (limited only by memory needed for each timer entry).  They can be
one-shot or periodic, and associated with a Python callback.

There is a very small overhead added to the SysTick IRQ, which could be
further optimised in the future, eg by patching SysTick_Handler code
dynamically.

When a SPI bus is initialized with a SPI host that is currently in use the

Damien George 1582c7eeb0 unix,windows: Enable module weak links. 2019-10-22 16:23:43 +11:00
Damien George d2384efa80 py: Automatically provide weak links from "foo" to "ufoo" module name.
This commit implements automatic module weak links for all built-in
modules, by searching for "ufoo" in the built-in module list if "foo"
cannot be found.  This means that all modules named "ufoo" are always
available as "foo".  Also, a port can no longer add any other weak links,
which makes strict the definition of a weak link.

It saves some code size (about 100-200 bytes) on ports that previously had
lots of weak links.

Some changes from the previous behaviour:
- It doesn't intern the non-u module names (eg "foo" is not interned),
  which saves code size, but will mean that "import foo" creates a new qstr
  (namely "foo") in RAM (unless the importing module is frozen).
- help('modules') no longer lists non-u module names, only the u-variants;
  this reduces duplication in the help listing.

Weak links are effectively the same as having a set of symbolic links on
the filesystem that is searched last.  So an "import foo" will search
built-in modules first, then all paths in sys.path, then weak links last,
importing "ufoo" if it exists.  Thus a file called "foo.py" somewhere in
sys.path will still have precedence over the weak link of "foo" to "ufoo".

Jim Mussared 912892b209 esp32: Add missing and necessary newline at EOF for sdkconfig.240mhz.
When these files get concatenated the newline-at-EOF is necessary so that
the start of the next file doesn't join with the end of the previous.

Jim Mussared 8ba963cfa3 tools/makemanifest.py: Eval relative paths w.r.t. current manifest file.
When loading a manifest file, e.g. by include(), it will chdir first to the
directory of that manifest.  This means that all file operations within a
manifest are relative to that manifest's location.

As a consequence of this, additional environment variables are needed to
find absolute paths, so the following are added: $(MPY_LIB_DIR),
$(PORT_DIR), $(BOARD_DIR).  And rename $(MPY) to $(MPY_DIR) to be
consistent.

Existing manifests are updated to match.

Damien George 12413e92a3 stm32/powerctrlboot: Fix config of systick IRQ priority on F0/L0/WB MCU.
Prior to this commit the systick IRQ priority was set at lowest priority on
F0/L0/WB MCUs, because it was left at the default and never configured.
This commit ensures the priority is configured and sets it to the highest
priority.

Josh Lloyd 59c1b7d4b8 esp32/boards: Split out CPU frequency config, make 160MHz the default.
Remove the 240MHz CPU config option from sdkconfig.base and create a new
sdkconfig.240mhz file for those boards that want to use 240MHz on boot.

The default CPU frequency is now 160MHz (was 240MHz), to align with the ESP
IDF and support more boards (eg those with D2WD chips).

Fixes issue #5169.

Jim Mussared 4b2b05718a esp32: Run NimBLE on the app core.
This prevents issues with concurrent access to the ringbuf.
MICROPY_BEGIN_ATOMIC_SECTION is only atomic to the same core.  We could
address this with a mutex, but it's also not safe to call mp_sched_schedule
across cores.
