QT PY ESP32-S3 won't mount

Post by edmason »

Received a new QT PY ESP32-S3 and trying to load circuit python on the board. Trying to follow the quickstart guide and can't seem to get the board to mount so I can copy over the UF2 file. Led on the board just cycles through it's rainbow of colors and regardless of button presses it won't mount. Shows as a bluetooth device but no disk ever gets mounted. Have tried multiple cables and both Windows and Mac with no luck. Any ideas?

Double check the QT Py and verify which specific ESP32 variant it is. There are a lot of similar/confusingly named boards.

Do you have one of these?

Are you able to double press reset and get the QTPYS3BOOT folder to show up?

Yes it is this item:

I can double click reset but the folder does not show up. Led goes solid white for a second and then just cycles through a rainbow colors.

See if you can get a COM port to show after entering ROM bootloader mode. This is a lower level bootloader mode with a different button sequence:

For now, just see if a COM port will show up. Don't worry about the remaining programming steps.

Yes, I'm able to connect to the board and can see it in the ESPTool. I have not tried to Erase and reload it yet, but I can try that if you think that's the next step.

OK, sounds like the board is fine in terms of general hardware functionality.

Yep, now go ahead and try the rest of the install process on that page. That'll reload the UF2 bootloader - which is a secondary bootloader to the ROM bootloader. It's the UF2 bootloader that is needed to provide the QTPYS3BOOT folder to which CircuitPython firmware UF2 can then be dragged.

Cool. Not sure what was going on originally. And it may happen again for various reasons. Sometimes things can just get in a weird state. But should always be able recover via that same process. Unlike the secondary UF2 bootloader, the ROM bootloader is baked in and should always work.

Good to know. This was brand new in a sealed package, so surprised it did it right from the start. At least I know how to get it working again :-)
