robert-hh 6482eb142c mimxrt/mpbthciport: Allow disabling UART flow control for BLE.
Not all boards or BLE extensions have the flow control signals for BLE
available at suitable pins.  Actually none of the Adafruit extensions
match for flow control.

For consistency with the previous behaviour it is enabled by default.

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
