Damien George 6e71cde6aa ports: Use default VFS config for import_stat and builtin_open.
For ports with MICROPY_VFS and MICROPY_PY_IO enabled their configuration
can now be simplified to use the defaults for mp_import_stat and
mp_builtin_open.

This commit makes no functional change, except for the following minor
points:
- the built-in "open" is removed from the minimal port (it previously did
  nothing)
- the duplicate built-in "input" is removed from the esp32 port
- qemu-arm now delegates to VFS import/open

The Renesas RA port

This is a port of MicroPython to the Renesas RA family of microcontrollers. Currently supported features are:

  • Filesystem on the internal flash using FatFs.
  • utime module with sleep, time, and ticks functions.
  • uos module with VFS support.
  • machine module with the following classes: Pin, ADC, I2C, SPI, SoftI2C, SoftSPI, UART, RTC
  • sdcard driver if frozen driver is installed.

Currently supported board product names are:

  • EK-RA6M2
  • RA4M1 CLICKER
  • EK-RA6M1
  • EK-RA4M1
  • EK-RA4W1

Please refer to the quick reference of renesas-ra port for more information about the boards.

Build instructions

  • MicroPython cross-compier The MicroPython cross-compiler must be built first, which will be used to pre-compile (freeze) built-in Python code. THis 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/renesas-ra/ directory.

  • Arm compiler 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 and Windows hosts via https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads. The compiler can be changed using the CROSS_COMPILE variable when invoking make.

  • Obtain submodules First the submodules must be obtained using:

    $ make submodules
    
  • Build binary image .hex Then to build for a given board subdirectory name, run:

    $ make BOARD=RA6M2_EK clean
    $ make BOARD=RA6M2_EK
    

    The default board subdirectory name is RA6M2_EK (which is for EK-RA6M2 board) but any of the names of the subdirectories in the boards/ directory can be passed as the argument to BOARD=; for example RA4M1_CLICKER, RA4M1_EK, RA4W1_EK and RA6M1_EK. The above command should produce binary images firmware.hex in the build-RA6M2_EK/` subdirectory (or the equivalent directory for the board specified).

Supported/Unsupprted funtions

Please refer to the renesas-ra quick reference.
