Thanks Alan
I'll get my serial cable and put it on the 3 pins and try to connect the
board.
Bye

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.
BR,
Alan

Hi
I'm trying to work on Arduino Minima under NuttX. My idea is to
port pysimCoder on R4 MINIMA.
I can compile and flash nuttx.hex, but I don't reach to open the
shell via USB (/dev/ttyACM0)...
By launching
$ tio /dev/ttyACM0
I obtain
[18:21:44.812] tio 3.8
[18:21:44.812] Press ctrl-t q to quit
[18:21:44.813] Connected to /dev/ttyACM0
but no shell... What I'm doing wrong? What I have to do to
communicate with the board? The /dev/ttyACM0 is available only if
BOOT is connected to GND (as by flashing, but otherwise the
/dev/ttyACM0 is not available)...
I can see the device in "usbview":
Thanks for any hint!
Roberto
