Hey @WolfSchouten, the device should be now fixed up and working properly.
What we found, is that some system files were in a corrupt state, unfortunately one of them being balena, hence the supervisor / application couldn’t run. We’ve replaced that binary with the correct one, and the device started up.
As test, run another update on the device, that seems to have gone okay, but after restart I see some other files in corrupt state (checking by the fingerprints shipped with the device). So the device works now, but cannot guarantee what’s going to happen, if files getting corrupted.
This to me suggest that the SD card is in a bad state, and would recommend replacing it, as otherwise it might keep corrupting the system. What make/brand SD card are you using? We strongly recommend more robust cards such as Sandisk Extreme Pro, which hasn’t let us down yet (while a lot of common cards do have such a short life time for IoT application).
What do you think?
