Duet 2 Ethernet - no Ethernet after Firmware upgrade

droftarts

@xxexx Is config.g being executed when powered from VIN? I don't know why it wouldn't be, and can't think of a way of checking without plugging in USB. You can connect USB under VIN power; you just need to take some precautions. See https://docs.duet3d.com/User_manual/Overview/USB_ground_loops
What firmware version were you on previously? Maybe rerun the update, or try reverting to the previous version you were using. Though I can't think why the firmware version would be causing this issue.

@xxexx I think the voltage regulators look okay. How old is this board? Where did you buy it from?

i checked the system directory: it is empty (!). I now try to install the Duet2combinedfirmware .bin file - "Connection lost, attempting to reconnect..."

@xxexx sounds like the sd card has been wiped then. maybe try a different sd card

@xxexx then you need to put all your config files back. hopefully you've got a backup otherwise use the configurator to generate a base set of files
