On the default rootfs, the recovery port acts as a recovery serial port. How can I recreate this behavior on my own image which doesn’t use systemd? Currently, /dev/ doesn’t have ttyGS0 listed, which is what the default image uses as far as I can tell. Is there a kernel module that’s not loaded?
Any pointers towards getting a non systemd OS running on here (serial-wise or just in general) are much appreciated.
