Hi Joe,

I don't know about your minicom configuration in linux.

1) sudo minicom -s

2) i) sudo su

ii) minicom -s

1) Can you please try to install "putty" in linux ?

2) Try to open "cat /dev/ttyUSB0" to check the bootup logs.

Ex,

root@titus-desktop:/#
root@titus-desktop:/#
root@titus-desktop:/# cat /dev/ttyUSB0   ( I'm switching ON my EVM here)
