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).

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.
timemodule with sleep, time, and ticks functions.osmodule with VFS support.machinemodule with the following classes:Pin,ADC,PWM,DAC,I2C,SPI,SoftI2C,SoftSPI,UART,RTC,SDCard.sdcardmodule for MCUs without nativemachine.SDCardsupport.
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-crossThis 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 compileris required for the build, along with the associated binary utilities. The default compiler isarm-none-eabi-gcc, which is available for Linux, Mac and Windows hosts via https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads. The compiler can be changed using theCROSS_COMPILEvariable when invokingmake. -
Protocol buffer compiler Building for the
ARDUINO_PORTENTA_C33board will build theesp_hosteddriver, that depends on the Protocol Buffer Compiler being installed. On Debian/Ubuntu, this can be installed withsudo apt-get install protobuf-compiler. -
Obtain submodules First the submodules must be obtained using:
$ make submodules -
Build binary image
.hexThen to build for a given board subdirectory name, run:$ make BOARD=EK_RA6M2 clean $ make BOARD=EK_RA6M2The default board subdirectory name is EK_RA6M2 (which is for EK-RA6M2 board) but any of the names of the subdirectories in the
boards/directory can be passed as the argument toBOARD=; for exampleRA4M1_CLICKER,EK_RA4M1,EK_RA4W1andEK_RA6M1. The above command should produce binary imagesfirmware.hexin the build-EK_RA6M2/` subdirectory (or the equivalent directory for the board specified).
