CircuitPython 9.2.2 on WeAct STM32F411CE BlackPill (with flash) no CIRCUITPY folder and freeze the dev board.

[fausterix]

Hi!

After flashing adafruit-circuitpython-stm32f411ce_blackpill_with_flash-en_US-9.2.2.bin on a WeAct STM32F411CE BlackPill
(buyed on the official WeAct store on AliExpress) no CIRCUITPY folder appear and the MCU get stuck.

With adafruit-circuitpython-stm32f411ce_blackpill_with_flash-en_US-9.2.1.bin no problems, it works as expected.

Thank you

I think this is another manifestation of #9956. STM chips also use the newly refactored dwc2 driver.
@hathach this could be another testbed.

@dhalbert maybe bump up tinyusb could fix this, there is a couple of dwc2 fixed since last pull from cpy hathach/tinyusb#2901 hathach/tinyusb#2891

Hi!

Actually even with CP 9.2.3 I'm having the same issue.

Thanks and regards

@fausterix I added a fix for this post 9.2.3. Could you try the aboslute latest build from https://adafruit-circuit-python.s3.amazonaws.com/index.html?prefix=bin/stm32f411ce_blackpill_with_flash/ ?

Hi!
Just tested https://adafruit-circuit-python.s3.amazonaws.com/bin/stm32f411ce_blackpill_with_flash/en_US/adafruit-circuitpython-stm32f411ce_blackpill_with_flash-en_US-20250126-main-PR9996-52b5b2d.bin and it works!
Thank you!
