W-111 : Display firmware update error - updating EVCS from 1.23 to 2.05

[W4Steli (Stefan Müller)]

I have a freshly installed EVCS at a customer. I installed the little power enhancer circuit that was in the packaging and at 1.23 the station was behaving normally.

After i updated to firmware version 2.05 the base system is trying to do the update for the display firmware, but that fails.

Behavior is that its a round trip game:

1. Display firmware update starts … writes data till exactly 98304 bytes fast … then stopps
2. Then it waits for roughly 30seconds (didn’t stop that)
3. Seems to reset and writes a message “System Data ERROR!”
4. after a couple seconds the game starts again

Interresting is thats always the exact same place where it gets stuck updating. For testing i tried to go back to V1.30 and then to V2.02 …. but that changed nothing.

So now im stuck a bit Any advice what i could do?

Hello @W4Steli. It might be some problems with display communication. I can check that EVCS if you add me to VRM installation. Will send you PM.
