libretiny: Generic RTL8710BX doesn't start after a reboot

Hi @kuba2k2,

The Generic RTL8710BX (mentioned in my previous support requests) doesn’t start after sending a restart command or after an OTA firmware upgrade. https://docs.libretuya.ml/boards/generic-rtl8710bx-4mb-980k/

If I unplug it and plug it again it starts up.

That’s weird, since I added another function to reset the chip few days ago. But that’s a story for another issue I think. I’m glad that OTA upload works now 👍

Okay, actually, hold up with that for a minute @mihsu81 … sorry for the confusion.

Seems like I found a bug in the implementation, that produces same results for me as your corrupted firmware. I’ll work on it and let you know.

Thanks @dbuezas. I’ve tried it but the compilation fails.

@mihsu81 okay, I see the corrupted characters. I’ll look into the dumps you posted later today.

About the exception decoder: it’s showing you a warning that firmware.elf doesn’t exist. I don’t know why but Esphome uses a different build folder name… Like .pioenvs instead of .pio. I’ll have to fix this somehow, but for now you can put the firmware.elf that Esphome compiled, into the path that PIO monitor shows it expects.

@dbuezas honestly I don’t think it’s caused by network issues. I see it happens when using OTA2 mostly, so there may be some problems with UF2 binpatching. That would explain the corrupted characters.
