Hi everyone, I’ve got a BPI-R4 and was playing around with it. I was able to install a basic Linux (Gentoo in my case) and got it to boot my kernel. Everything was working well. But when I tried to boot the BPI next morning the serial console stopped working. I get only gibberish output. Though the BPI seems to boot. It’s just the output that’s messed up.

I get the same result for ch341 as well as for FTDI device. Any Idea what went wrong? Seems to me like a hardware defect. Can the BPI be saved?
