I am trying to update a sub-set of our B523 fleet to DeviceOS 3.0.0 to increase stability and use resumable downloads of OTA bins. However, what we see is that almost all devices start the OTA updating process, goes offline and then after some time, fails. it retries a couple of times after which we see that the units become somewhat “bricked” - pressing RESET does not affect the device state in any way. It does not go online, it does not run application firmware or anything. It simply flashes white and shuts off the LED again.
It is not a problem to do a wired update during production, but we still have a lot of units out in the wild and we cannot risk bricking devices that are +14.000 km away. I’ve tried testing a bin-file without application firmware, but only compiled against 3.0.0 to minimize the bin size, but even this fails somehow.
Anyone else having problems updating from 2.0.1 to 3.0.0?
