Note this is only an issue for updating to 1.20.2.rc7 (1.20.2.rc6 is okay)

I'm trying to do an OTA firmware update to 1.20.2.rc7 from 1.20.1.r2, and I get the following error:

E (56) esp_image: image at 0x210000 has invalid magic byte
Cannot load Firmware img in the active partition! .. Defaulting back to previous partition

Here is the full log:

It then resets into the original firmware.

Any ideas?

Hi @troy-salt

I tried the OTA firmware update on WiPy from 1.20.1.r2 to 1.20.2.r7 using OTA firmware update example and the update worked fine. Please refer to this example (https://docs.pycom.io/tutorials/all/ota/) for the exact steps to perform an OTA update.

The image file that you have in the flash seems to be corrupt. Make sure that the file is written correctly.
