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
