Carlosgg f3d1495fd3 all: Update bindings, ports and tests for mbedtls v3.5.1.
Changes include:

- Some mbedtls source files renamed or deprecated.

- Our `mbedtls_config.h` files are renamed to `mbedtls_config_port.h`, so
  they don't clash with mbedtls's new default configuration file named
  `mbedtls_config.h`.

- MBEDTLS_TLS_DEFAULT_ALLOW_SHA1_IN_KEY_EXCHANGE is deprecated.

- MBEDTLS_HAVE_TIME now requires an `mbedtls_ms_time` function to be
  defined but it's only used for TLSv1.3 (currently not enabled in
  MicroPython so there is a lazy implementation, i.e. seconds * 1000).

- `tests/multi_net/ssl_data.py` is removed (due to deprecation of
  MBEDTLS_TLS_DEFAULT_ALLOW_SHA1_IN_KEY_EXCHANGE), there are the existing
  `ssl_cert_rsa.py` and `sslcontext_server_client.py` tests which do very
  similar, simple SSL data transfer.

- Tests now use an EC key by default (they are smaller and faster), and the
  RSA key has been regenerated due to the old PKCS encoding used by openssl
  rsa command, see
  https://stackoverflow.com/questions/40822328/openssl-rsa-key-pem-and-der-conversion-does-not-match
  (and `tests/README.md` has been updated accordingly).

Port of MicroPython to NXP iMX RT 10xx

Currently supports Teensy 4.0, Teensy 4.1, and the MIMXRT1010_EVK, MIMXRT1020_EVK, MIMXRT1050_EVK, MIMXRT1060_EVK and MIMXRT1064_EVK boards.

Features:

  • REPL over USB VCP
  • machine.ADC
  • machine.I2C
  • machine.LED
  • machine.Pin
  • machine.PWM
  • machine.RTC
  • machine.SDCard
  • machine.SPI
  • machine.Signal
  • machine.SoftI2C
  • machine.SoftSPI
  • machine.Timer
  • machine.UART
  • LFS2 file system at the internal Flash
  • SDCard support (not on MIMXRT1010_EVK)
  • Ethernet (not on Teensy 4.0 and MIMXRT1010_EVK)

Known issues:

TODO:

  • More peripherals (Counter, I2S, CAN, etc)
  • More Python options

Build Instructions

Before building the firmware for a given board the MicroPython cross-compiler must be built; it will be used to pre-compile some of the built-in scripts to bytecode. The cross-compiler is built and run on the host machine, using:

$ make -C mpy-cross

This command should be executed from the root directory of this repository. All other commands below should be executed from the ports/mimxrt/ directory.

An ARM compiler is required for the build, along with the associated binary utilities. The default compiler is arm-none-eabi-gcc, which is available for Arch Linux via the package arm-none-eabi-gcc, for Ubuntu via instructions here, or see here for the main GCC ARM Embedded page. The compiler can be changed using the CROSS_COMPILE variable when invoking make.

In addition newlib is required which is available for Arch Linux via the package arm-none-eabi-newlib, for Ubuntu/Debian install package libnewlib-arm-none-eabi

Next, the board to build must be selected. Any of the board names of the subdirectories in the boards/ directory is a valid board. The board name must be passed as the argument to BOARD= when invoking make.

All boards require certain submodules to be obtained before they can be built. The correct set of submodules can be initialised using (with SEEED_ARCH_MIX as an example of the selected board):

$ make BOARD=SEEED_ARCH_MIX submodules

Then to build the board's firmware run:

$ make BOARD=SEEED_ARCH_MIX

The above command should produce binary images in the build-SEEED_ARCH_MIX/ subdirectory (or the equivalent directory for the board specified).

Flashing

Deploy the firmware following the instructions here https://docs.micropython.org/en/latest/mimxrt/tutorial/intro.html#deploying-the-firmware
