Hello!
When visiting a device via its access point, there can be an option to upload a file for an OTA update.
However, if the user accidentally selects the file in the “modern” (Factory) and not the “legacy” (OTA) format, the OTA update will fail with:
Update Failed: Wrong Magic Byte
It took me a while to find this:
Serial flash uses the “modern” format. OTA update uses the “legacy” format.
See related discussion:
Is it possible to add a note in this regard on the WebGUI that comes along with the AP and “OTA Update” section? And/or provide the detail with the aforementioned error message, e.g.:
Update Failed: Wrong Magic Byte - check correct OTA vs. Factory format
Thanks for your kind consideration and for upvoting it if you feel it is worth it👍
