I sucessfully installed my apu2 some weeks ago via serial console usb adapter.
today i need again access per console.
but now it does not work anymore. i do not get any messages in my terminal.
what i already tried:
check de adapater with paper clip on pin 2+3. this worked.
i also found out that if i'm connected with a terminal and i send a break command. the terminal shows me one time the actual console. e.g.:
"FreeBSD/amd64 (OPNsense.localdomain) (ttyu0)
login:" or while the device is booting the boot messages. but it does only refesh if i send another break. i cannot enter something.
i also tried to push the s1 button during boot.
i also tried another terminal app.
