A9 and M4 serial communication problem. ttymxc3 not found

Hello. Nice job with the board. Looking forward to making some cool projects with it. I need some help though. I am trying to get the UDOOubuntu to talk to the Arduino over serial. The Arduino can print to Serial and I can see it on 'ttyMCC'.

When I try to send a message the other way over 'ttymxc3' using python I have a problem. I get a message saying 'ttymxc3' does not exist. After entering the command 'ls /dev/ttymxc*' only 'ttymxc0' and 'ttymxc2' are listed. Dont know what the problem is here. Thanks.

really no one can help with this?

 

On the Neo you'll have to use

Code:

ttyMCC

for the communication between A9 and M4
