Fix OTA on 8266 #17

Closed Sonic-Amiga closed 1 year ago

Sonic-Amiga commented 1 year ago

ESP8266 requires app partition addresses to only differ by one bit. If this requirement isn't met, the chip will unrecoverably crash after the update; reflashing over the wire will be needed.

Hello! This is why OTA didn't work on 8266. Looks like some bug in bootloader.

I am intentionally posting this as a separate PR because you could have some reasons why you arranged your partitions in that specific order; in this case this change would become more complicated. For now i am just KISS; in my opinion this should not harm ESP32.

Very wary of partition changes, may make sense to force a specific 8266 partition table in the set build stuff.

Okay; that's exactly why i post it separately. Well redo. BTW, i have questions. What is this "fctry" partition for exactly ?

And one more. Since i've got the OTA working, would you agree to host my binary on your OTA server ? I don't have resources to run my own; plus a single binary isn't worth it.

And i'm way too lazy to rewrite the OTA code once again adding file upload form.

Factory is for matter, but may ultimately not even be necessary. I have yet to finish it.

And yeh, I can host on my OTA.

Hi again! I've redone the patch, now there are special -8266 versions of the CSVs. I didn't throw anything away in order to be forward-compatible
