Can not open serial port in IDE

Hello,

My O.S. is Linux Lite (ubuntu).

I am getting "No such port: '/dev/ttyACM0' msg when I try to open the internal serial monitor in the IDE. I also tried /ttyACM0, etc..

When I use the Aruduino ide I can access the port successfully.

Thanks

From your description the problem seems to be related to your Linux system. A quick way to verify this is to short the TXD and RXD serial port pins together, what's called a loopback. Open the serial port and see if the characters you send are echoed back. If not then the problem is not in the STM32 board.

But I can use a different IDE without a problem, the arduino IDE using the same PORT. I do not have both IDE's open at the same time.

Thanks for responding.
