8.x is bootlooping on my ESP-C3-32S (2M), while 7.3.3 runs fine:

My board looks a bit different from the one on the images.

Could you try erasing the flash completely and then reinstalling the UF2 bootloader and trying 8.0.x again?

[Neradoc]

Trying a full erase is a good idea, note that it's a C3, no uf2 bootloader. I believe it's also the only 2MB C3 we have apparently ? So maybe there's an issue with the 2MB partition ?

I always full erased before flashing. I also tried multiple times with different settings, speeds etc. I even tried the web flash.

Moved to long term because none of us Adafruit-funded folks have this board. QTPy C3 doesn't boot loop.

Perhaps as a hack we could try flashing a 2mb partition table on a 4mb board. That should work.

i have the same problem i works fine on 7.3.3 but the versions afer 8.0.0 makes it stuck in bootloop ( the same board)

I cannot find this to buy; it appears to be discontinued. If you have a US-purchase link, could you post it?

I looked through the changes between 7.3.3 and 8.2.0 and I don't see what would cause this. There are changes which partition table file are used, but those changes just seem to be renamings.

If anyone feels like doing a bisect, that would be great. Maybe start with 8.0.0-alpha.1 and see if that fails, and then bisect main vs that. But it requires an experienced builder. An alternative is to try all the 8.0.0 alpha and beta versions, and see which one is the first to cause a failure.

I have a vague memory which may be wrong of some revisions of these AI-Thinker boards happening under the same part number.

Thanks for the support I’ll check all the versions (alpha and beta) And find which version it fails I’ll let you know -parsa

@microdev1 is there a possibility you can investigate this? I noticed that the addition of "storage extension" occurred between 8.0.0-beta1 and beta2. This particular board, with 2MB flash, has no OTA partition.
