It is possible that a previous instance of pyocd was still running, occupying those ports. Or pyocd did not exit cleanly so the OS has a TIME_WAIT on those sockets. Did you perform a debugging session just before this happened? Maybe that debugging session was still in progress?
Im using DAPlink(USB) . this is my first debug , antyhing done before and i get always the same error. Can you provide with daplink config ? is there something in debug to set in order to get debug session work fine ?
I have never used DAPlink and don't have one to try. Could you try running west debug in command line? If it is still an issue there, it might be caused by the underlying cmake/west mechanisms and we can file a bug at the main Zephyr repo.
My Daplink is always at "/dev/ttyACM0" and when i open terminal view on eclipse, it tell me that port is closed. I verify if the port is realy closed and it's seem to be ok and any process have been attached to it. I think you should make bug on zephyr repos to correct this . i have always the same error
