OTA update for Huzzah 32 v2


I am having difficulty performing a host firmware update for the Adafruit Feather V2. I keep encountering the following error:

Error (cannot update host: {odfu-init}: esp: cannot connect to target (2))

From my understanding, this is a timeout issue. I am using the Notecarrier-f v1.3. After reading other posts, I got the impression that the OTA host firmware update might not work for some Adafruit ESP32 boards.

Has anyone managed to make it work on the Huzzah 32 v2?


Hi @theogrm,

The BOOT pin is not exposed on the HUZZAH32 v2, so unfortunately OTA firmware updates won’t work on that board.
