I trying to write some messages over the UART of the STM32F4-Discovery board. I know that in Qemu we have a flag to redirect the UART of the board to a serial port with --serial pty.
I'm using that flag, but I'm not able to see anything.
I think that the code is working, because if I write -d cpu, I see activity inside.
I would like to know if is possible send data to the UART of the board in GNU MCU Eclipse QEMU?
Also, I'm trying to execute some RTOS like NuttX, and it looks that doesn't crash, but I'm not see anything in the UART.
Thank you so much for the help!
as far as I remember, the documentation does not mentions UART as functional.
there were several contributors trying to implement the serial port for the STM32F devices, but no one did it completely.
