OLIMEX - ESP32-GATEWAY Red light after Firmware Upgrade
2 CommentsSorted by Newest First
I did try to load an earlier version, but that did not help. What I did have to do to get it working again, was to wipe the unit, and reload the correct version. This all came down to me loading version e, instead of version f onto the unit.
It's all back in operation once again.

It looks like the firmware load was successful and verified. Have you tried older firmware that you know works?

Hi All
I tried to upgrade the firmware from v4.1.5 to v4.1.6, however the board is no longer responding and has a red power led on, and nothing else responds.
The upgrade was done from the Web Interface, and looked to go correctly. I restarted the WiFi unit via the web interface, and that is when I lost response to the unit.
I did note that on the EVSE Display there was a message indicating that the firmware upgrade was complete (Sorry I did not take note of the exact message) and had been there for some time, approx 30mins. At this point I powered the EVSE off, and back on again. There is no indication from the EVSE display of any wireless unit being attached. I've tried to power cycle the unit several times, both connected to the EVSE, and separately via the USB cable.
I've tried to manually flash the firmware onto the unit running the command below, with the following output, but still the same non responsive result. I've tried to flash a couple of earlier versions on the unit, but all have the same result.

Is anybody able to advise how I can get this unit going again, or have I created a paperweight?
Cheers
