Hello acostash and alexgg,
That worked! Changing the ttymsc0 → ttymsc3 in the layer.conf. I get the login screen on my serial terminal and everything prints out.
Is there any plan on supporting the VAR-SOM-MX8M-MINI since it uses the same image / yocto receipts as the DART-MX8M-MINI? From my testing, everything else seems to be working and I was able to run a container.
Thanks so much for the help! I knew there were smarter people out there than me that has been stumbling on this issue for almost a week
