Add support for WeAct Studio RA4M1 Board

[arwidcool]

I've had some success by using the UNO R4 Minima as the board selection, and using JLink. Not perfect, but can get it going.

Having some issues initializing a blink sketch, Says programming is successful . The pin mapping on the LED corresponds to "pin 21" on the Arduino. Do you have your blink code?

(EDIT:)

Got it working.

You need to add "frequency = 48000000L" to the platformio.ini file

I also flashed the bootloader before direct via Renesas Flash Programmer but I am not sure if that helped.

Also was able to get unexposed pins working by first adding the pin to :
"extern "C" const PinMuxCfg_t g_pin_cfg[] " location in variant.cpp
Example : PIN 206 to D17 : {BSP_IO_PORT_02_PIN_06, P206}, /* (27) D17 */
and then defining the array position in pins_arduino.h
and adding the "#define PIN_D17 (27u)"

Were 27U is the array position. This way by calling PIN_D17 should call array position 27

I am just finishing up another project and I will sit down and re-edit the arduino uno minima board files and the framework variants to work with the renesas board as a board selection.

That sounds good. In the end I started playing with the RASC directly:

Using the the Minima board and flashing with jlink when setting the cpu freq i was able to get the USB working no issues btw, so it has all the features and you can expose the pins.

I second this one.

I ordered one. If I can set up the board correctly I will link it for someone to check over.
