Behavior

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.
