[SOLVED] can't connect to REPL

Reboot as the big hammer should work.

If you get the "busy" error that means that some other process already has the port open.

You should be able to use the lsof command to determine who has the port open:

Code: Select all

$ lsof | grep ttyACM0

[SOLVED!]

Now I found the solution...

1. unplug the pyboard
2. type:

Code: Select all

ls /dev/ttyACM*

3. plug the pyboard
4. type:

Code: Select all

ls /dev/ttyACM*

5. figure out the new device, this is the pyboard (in my case: /dev/ttyACM3)
6. then, use this new device address to connect!

Code: Select all

sudo picocom /dev/ttyACM3

For some reasons I have now other devices , so the pyboard is now device number 3.

I had trouble for a while with the modem manager, which tried to capture the pyboard interface and configure it as a modem. That went away after I uninstalled the modem manager,
