A, yes. I read your commend too quickly. Glad to hear you got it working :)

Thank you for your answer. It's already working on my environnement but only with cu.

I use :

ls /dev/tty*

to find the USB name

Thank you very much

You need to replace the 'x' in /dev/ttyACMx with the correct number in your case, typically 0. (You should be able to see it from dmesg when you plug in the device, and also /var/log/messages or /var/log/syslog). One way to determine t is to grep for ttyACM:

dmesg | grep ttyACM

I'm working on linux.

Putty doesn't work but I'm using " cu " :

cu -l /dev/ttyACMx -s 115200 --parity=none

Yes, this works on Linux as well, and you should see the UART device as /dev/ttyACMx. (You have to install the J-Link Software Pack in order to use it.)

Yes. The UART pins (P0.05 to 8 as you write) are internally connected to the on-board Segger debugger chip and it will be available on you PC as normal COM port. For this you do not have to connect TX, RX, RTS and CTS to the PC. It will be seen as "JLink CDC UART Port (COM*)" in Windows.
