Hi Roberto, I tested NuttX on an Arduino R4 Minima board and it worked like a charm!
The point is: we don't have the serial console at the USB connector by default (I think we just need to change the port in the menuconfig). So to get the serial console working you need to use the RX and TX pins (pin 0 and 1) of the R4 board. I create a tutorial: https://acassis.wordpress.com/2025/03/28/testing-nuttx-on-arduino-r4-minima-board/ BTW, I think our Documentation for almost all boards is really bad! What do people expect when going to the supported board? The steps explaining how to compile the board! We don't have it for our boards, we have a lot of loose information that doesn't help too much. This is not only for Arduino R4 Minima: https://nuttx.apache.org/docs/latest/platforms/arm/ra4m1/boards/arduino-r4-minima/index.html It is for almost all boards. I think we need to standardize what we expect to see at the supported boards.
