Maureen Helm 8b061f2d79 zephyr: Fix floating point configuration.
Zephyr renamed CONFIG_FLOAT to CONFIG_FPU to better reflect its semantics
of enabling the hardware floating point unit (FPU) rather than enabling
toolchain-level floating point support (i.e., software floating point for
FPU-less socs).

Maureen Helm 38b4f1569e zephyr: Fix and rename stacks_analyze function in zephyr module.
Zephyr deprecated and then removed its stack_analyze function because it
was unsafe.  Use the new zephyr thread analyzer instead and rename the
MicroPython function to zephyr.thread_analyze() to be more consistent with
the implementation.

Tested on mimxrt1050_evk.

The output now looks like this:

>>> zephyr.thread_analyze()
Thread analyze:

Albort Xue 05e5d411b5 mimxrt/boards: Set __heap_size__ to 0 in MIMXRT1011.ld.
Do not use the traditional C heap in order to save memory, because the
traditional C heap is unused in MicroPython.

jp-96 3705bc418c extmod/modbluetooth: Register default GATT service and fix esp32 init.
This is for the NimBLE bindings, to make sure the default GATT service
appears and that the esp32 initialises NimBLE correctly (it now matches
stm32).

Philipp Ebensberger 6ac05af8e1 mimxrt/tusb_config.h: Preliminary fix for TinyUSB HS endpoint overflow.
Sending more than 64 bytes to the USB CDC endpoint in HS mode will lead to
a hard crash.  This commit fixes the issue, although there may be a better
fix from upstream TinyUSB in the future.

Damien George 621f40b12c esp32/mpthreadport: Fix calculation of thread stack size.
With this commit the code should work correctly regardless of the size of
StackType_t (it's actually 1 byte in size for the esp32's custom FreeRTOS).

Fixes issue #6072.

Philipp Ebensberger 02cc4462b7 mimxrt: Add initial impl of machine.LED class, and basic pin support.
This commit implements an LED class with rudimentary parts of a pin C API
to support it.  The LED class does not yet support setting an intensity.

This LED class is put in the machine module for the time being, until a
better place is found.

One LED is supported on TEENSY40 and MIMXRT1010_EVK boards.

Damien George 8e591d412a minimal: Make build more flexible and work as 64-bit build.
Changes are:
- string0 is no longer built when building for host as the target, because
  it'll be provided by the system libc and may in some cases clash with the
  system one (eg on OSX).
- mp_int_t/mp_uint_t are defined in terms of intptr_t/uintptr_t to support
  both 32-bit and 64-bit builds.
- Configuration values which are the default in py/mpconfig.h are removed
  from mpconfigport.h to make the configuration a bit more minimal, eg as
  a better starting point for new ports.

Damien George 246f3f640d stm32/boards/xxx_WB55: Enable pyb.ADC and hardware SPI on WB55 boards.
These features are now supported (although machine.ADC is recommended over
pyb.ADC).

Damien George 68d053c66e stm32/modmachine: Allow changing AHB and APB bus frequencies on STM32WB.
For now SYSCLK cannot be changed and must remain at 64MHz.

Damien George 9ae50d22c9 stm32/machine_uart: Allow re-init'ing a static UART object.
Just disallow changing the rxbuf which will be some static RAM (can't free
it and soft-reset would lose any dynamically allocated buffer).
2020-06-01 21:41:54 +10:00
Damien George 88971342b1 stm32/machine_uart: Retain attached-to-repl setting when init'ing UART. 2020-06-01 21:41:50 +10:00
Joel Stanley f03d030080 powerpc/uart: Choose which UART to use at build time, not runtime.
Microwatt may have firmware that places data in r3, which was used to
detect microwatt vs powernv.  This breaks the existing probing of the UART
type in this powerpc port.

Instead build only the appropriate UART into the firmware, selected by
passing the option UART=potato or UART=lpc_serial to the Makefile.

A future enhancement would be to parse the device tree and configure
MicroPython based on the settings.

Thorsten von Eicken 50a7ba2348 esp32/modmachine: Fix machine.reset_cause to use IDF's esp_reset_reason.
The code previously called rtc_get_reset_reason which is a "raw" reset
cause.  The ESP-IDF massages that for the proper reset cause available from
esp_reset_reason.

Fixes issue #5134.

stijn 9523ca92e0 windows: Make appveyor.yml self-contained.
Add configuration which otherwise has to be set via the UI so the file is
more self-contained, and remove configuration which is not needed because
it's the same as the default.  The major change here is that for a while
now Appveyor has been using Visual Studio 2015 by default while we still
want to support 2013.

stijn 81db22f693 py/modmath: Work around msvc float bugs in atan2, fmod and modf.
Older implementations deal with infinity/negative zero incorrectly.  This
commit adds generic fixes that can be enabled by any port that needs them,
along with new tests cases.

Joel Stanley b65482ffa8 powerpc: Set better default compiler.
Most developers use a compiler which is called powerpc64le-linux-gnu-gcc.
2020-05-27 17:02:04 +10:00
Joel Stanley 25bc42e754 powerpc: Fix Makefile rule when linking.
The linker script was included in the "$^" inputs, causing the build to
fail:

 LINK build/firmware.elf
 powerpc64le-linux-gnu-ld: error: linker script file 'powerpc.lds' appears multiple times

As a fix the linker script is left as a dependency of the elf, but only the
object files are linked.

Olivier Ortigues e32302c1a6 esp8266/esppwm: Fix PWM glitch when setting duty on different channel.
The PWM driver uses a double buffer for the PWM timing array, one in
current use and the other one to update when changing duty parameters.
The issue was that once the duty parameters were changed the updated buffer
was applied immediately without synchronising to the start of the PWM
period.  By moving the buffer toggling/swapping to the interrupt when the
cycle is done there are no more glitches.

Jim Mussared e7f8c7d9a3 nrf: Update to work with nrfx v2.0.0, to match TinyUSB.
Commit 6cea369b89 updated the TinyUSB
submodule to a version based on nrfx v2.0.0.  This commit updates the nrf
port to work with the latest TinyUSB and nrfx v2.0.0.

Damien George 8f348778e1 nrf/mphalport: Remove need for "syntax unified" in mp_hal_delay_us.
Because it can confuse older versions of gcc.  Instead use the correct
instruction for Thumb vs Thumb-2 (sub vs subs) so the assembler emits the
2-byte instruction.

Related to commit 1aa9ff9141.

Damien George eb5e9c00f8 nrf/Makefile: Don't use -fno-builtin for Cortex-M0 builds.
So that error string compression is optimised correctly (it needs strcmp to
be optimised away by the compiler).

Rafael Römhild 8f3167a962 esp8266/boards: Allow configuring btree/FAT/LFS2 support when building.
Prior to e0905e85a7 it was possible to
disable btree support on build.  This patch allows to configure btree
support on make again and also the two new introduced options for FAT and
LFS2 filesystems.

Damien George 3b6c9119eb extmod/modbluetooth: Add support for changing the GAP device name.
This commit allows the user to set/get the GAP device name used by service
0x1800, characteristic 0x2a00.  The usage is:

    BLE.config(gap_name="myname")
    print(BLE.config("gap_name"))

As part of this change the compile-time setting
MICROPY_PY_BLUETOOTH_DEFAULT_NAME is renamed to
MICROPY_PY_BLUETOOTH_DEFAULT_GAP_NAME to emphasise its link to GAP and this
new "gap_name" config value.  And the default value of this for the NimBLE
bindings is changed from "PYBD" to "MPY NIMBLE" to be more generic.

Thorsten von Eicken ab4e197707 esp32/modsocket: Fix getaddrinfo to raise on error.
This commit fixes the behaviour of socket.getaddrinfo on the ESP32 so it
raises an OSError when the name resolution fails instead of returning a []
or a resolution for 0.0.0.0.

Tests are added (generic and ESP32-specific) to verify behaviour consistent
with CPython, modulo the different types of exceptions per MicroPython
documentation.

Damien George 67fca2b715 esp8266/uart: Move a few functions from iRAM to iROM.
They call functions in iROM so do not need to be in iRAM.
2020-05-08 23:44:57 +10:00
Damien George f2218c2fbd esp8266/esp_mphal: Move most functions in esp_mphal.c from iRAM to iROM.
The ones that are moved out of iRAM should not need to be there, because
either they call functions in iROM (eg mp_hal_stdout_tx_str), or they are
only ever called from a function in iROM and not from an interrupt (eg
ets_esf_free_bufs).

This frees up about 800 bytes of iRAM.
2020-05-08 23:44:57 +10:00
Damien George caa7725642 esp8266/boards: Move py/pairheap.c code from iRAM to iROM.
It doesn't need to be in iRAM.

Damien George e12de1fd9d esp8266: Clean up Pin intr handler by moving all code to machine_pin.c.
The macro MP_FASTCODE is used to explicitly place required functions in
iRAM, instead of needing a separate .c file.

Maureen Helm 25434e976b zephyr: Use zephyr build system to merge configurations.
The zephyr build system supports merging application-level board
configurations, so there is no need to reproduce this functionality in
MicroPython.

If CONF_FILE is not explicitly set, then the zephyr build system looks for
prj.conf in the application directory.  Therefore we rename the MicroPython
prj_base.conf to prj.conf.

Furthermore, if the zephyr build system finds boards/$(BOARD).conf in the
application directory, it merges that configuration with prj.conf.
Therefore we rename all the MicroPython board .conf files and move them
into a boards/ directory.

The minimal configuration, prj_minimal.conf, is left in the application
directory because it is used as an explicitly set CONF_FILE in
make-minimal.

Thorsten von Eicken 952ff8a8ea esp32: Improve support for OTA updates.
This commit adds several small items to improve the support for OTA
updates on an esp32:

- a partition table for 4MB flash modules that has two OTA partitions ready
  to go to do updates
- a GENERIC_OTA board that uses that partition table and that enables
  automatic roll-back in the bootloader
- a new esp32.Partition.mark_app_valid_cancel_rollback() class-method to
  signal that the boot is successful and should not be rolled back at the
  next reset
- an automated test for doing an OTA update
- documentation updates
