OTA Wifi UART update unsuccessful
Posted: Mon Feb 07, 2022 1:00 pm
Very interesting because I flashed successfully before, now this one seems to be in a stuck state.
Tried multiple firmwares, web interface loads, but params are empty -> no communicaton between WiFi & STM presumed.
Firmware size: 48k
Upload claims to be done after executing step -1, step 0, step1. Which add up to 370B, so less than 1% of the firmware.
Power cycling and retrying does not seem to make a difference, will have to remove it from the car so I can observe LED & possibly internal UART looking for "2D" messages.
Only JavaScript error I get is 404 for subscription.js, but I believe that is unrelated.
I might try updating it directly to the UART port like suggested here:

Just considered exposing UART TX & RX on the unobtanium connector but I don't think there are free pins. That would save me getting the inverter out of the car next time.
