Jim Mussared def76fe4d9 all: Use MP_ERROR_TEXT for all error messages. 2020-04-05 15:02:06 +10:00
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
    rm -rf .git/modules/lib/tinyusb
    git submodule update --init lib/tinyusb

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.

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.

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.

odewdney b51a2c266a lib/utils: Change default value of pyexec_mode_kind to 0 to put in bss.
By simply reordering the enums for pyexec_mode_kind_t it eliminates a data
variable which costs ROM to initialise it.  And the minimal build now has
nothing in the data section.

It seems the compiler is smart enough so that the generated code for
if-logic which tests these enum values is unchanged.

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.

Yonatan Goldschmidt dce590c29d lib/mp-readline: Add an assert() to catch buffer overflows.
During readline development, this function may receive bad `pos` values.
It's easier to understand the assert() failing error than to have a "stack
smashing detected" message.

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.

Damien George 09376f0e47 py: Introduce MP_ROM_NONE macro for ROM to refer to None object.
This helps to prevent mistakes, and allows easily changing the ROM value of
None if needed.

David Lechner 1605c7e584 Revert "lib/tinytest: Clean up test reporting in the presence of std..."
This reverts commit f4ed2dfa94.

This lets tinytest work as it was originally designed.  An alternate
solution for the reverted commit will be implemented in a future commit.

Jim Mussared 580a2656d1 stm32: Use hardware double sqrt on F7/H7 MCUs.
Identical to cd527bb324 but for doubles.
This gives a -2.754% improvement on bm_float.py, and -35% improvement on
calling sqrt in a loop.

Damien George af20c2ead3 py: Add global default_emit_opt variable to make emit kind persistent.
mp_compile no longer takes an emit_opt argument, rather this setting is now
provided by the global default_emit_opt variable.

Now, when -X emit=native is passed as a command-line option, the emitter
will be set for all compiled modules (included imports), not just the
top-level script.

In the future there could be a way to also set this variable from a script.

Fixes issue #4267.

Glenn Ruben Bakke 85bde0889d lib/nrfx: Upgrade nrfx to master.
Updating the nrfx git submodule containing HAL drivers for nrf-port
from v1.3.1 to current master. The version pointed to is one commit
ahead of v1.7.1 release. The extra commit contains a bugfix for
nrfx_uart_tx_in_progress() making it report correctly.

The general upgrade of nrfx is considered to be safe, as almost all
changes in between 1.3.1 and 1.7.1 are related to peripherals and
target devices not used by the nrf-port as of today.

Damien George 2459162599 lib/utils/interrupt_char: Invalidate interrupt char at start up.
Otherwise mp_interrupt_char will have a value of zero on start up (because
it's in the BSS) and a KeyboardInterrupt may be raised during start up.
For example this can occur if there is a UART attached to the REPL which
sends spurious null bytes when the device turns on.

Andrew Leech 859596ce25 lib/utils: Make pyexec_file_if_exists run frozen scripts if they exist.
So that boot.py and/or main.py can be frozen (either as STR or MPY) in the
same way that other scripts are frozen.  Frozen scripts have preference to
scripts in the VFS.

Damien George 06a532c227 lib/utils/pyexec: Add pyexec_file_if_exists() helper function.

From https://github.com/micropython/oofatfs, branch work-R0.13c,
commit cb05c9486d3b48ffd6bd7542d8dbbab4b1caf790.

Large code pages (932, 936, 949, 950) have been removed from ffunicode.c
because they were not included in previous versions here.

Mike Causer 812969d615 all: Change PYB message prefix to MPY.
Replaces "PYB: soft reboot" with "MPY: soft reboot", etc.

Having a consistent prefix across ports reduces the difference between
ports, which is a general goal.  And this change won't break pyboard.py
because that tool only looks for "soft reboot".

Damien George f5d46a88aa lib/utils/pyexec: Forcefully unlock the heap if locked and REPL active.

See issue #4205 and #4209.
