How to fix google coral devboard ssh connection issue

Question

I have been using the Google Coral Devboard in a project for a while. Today, I am surprised to see that using ssh does not work. Something went wrong somewhere. ssh [email protected] gives

ssh: connect to host 192.168.0.111 port 22: Connection refused

mdt devices does find the device though. mdt shell does not work due to the inherent failure of ssh connection.

I have checked the authorized_keys file and my own private keys and they match.

I can only connect to the devboard using Serial communication. I wish to reflash the entire thing and reset the board. However, after using sudo reboot-bootloader, fastboot devices sees nothing.

I have tried 4 USB C cables. I have tried using fastboot 0 from the Serial console immediately instead of letting the board boot up. Nothing shows up.

I tried using Windows 10 and WSL yet nothing is showing up.

I just want to either fix the ssh connection issue or simply factory reset the entire thing.

Answer 1

That' odd, it maybe because the board disconnection from the network. For the ssh/mdt issue, can you share this outputs:

$ nmcli connection show

Regarding fastboot issue, what if you try to initiate fastboot with an sdcard like this?
