I am testing Ethernet, Wi-Fi, and cellular connectivity on a Balena Fin to make sure connectivity is maintained when one of these interfaces goes down. To simplify debugging, I would like to access the console, issue CLI commands, and view logs over USB / serial, rather than SSH. I’ve seen some posts mention this in the forum but have not been able to figure out how to do it. How can I connect my laptop to the Balena Fin, and then be able to gain console / log access?
I tried connecting a microUSB cable to micro port on the Fin, but when I did this, I did not see a new COM port on either of my laptops (both Mac and Windows).
I confirmed that /mnt/boot/config.txt has “enable_uart=1”. What else am I missing?
