Hi, there
I just flash the package ArchLinuxARM-rpi-2-latest.tar.gz to my raspberry pi 3b+, and I try to control my device via serial port
But after I try to fix config.txt with code:
and cmdline.txt with code:
With my PC, has arch linux too, connect to my device with minicom, I can see the kernel messages from minicom, but I can not input anything
And, I think I got correct line connection
If anyone can help me please, I have no idea now
