weACT 2.0 stm32f411ce unable to enumerate USB device, probably board pullups #21

I'm using the F104c board configuration and flashing my WeACT Blackpill 2.0 Under Raspberry Pi OS and x86 Ubuntu I am not able to see a storage device attach when first connected. I need to press the Boot0 and NRST pins (DFU mode) to be able to see a dmesg result.

[19730.784295] usb 1-5: device descriptor read/64, error -71 [19731.020284] usb 1-5: device descriptor read/64, error -71 [19731.256268] usb 1-5: new full-speed USB device number 8 using xhci_hcd [19731.384229] usb 1-5: device descriptor read/64, error -71 [19731.620221] usb 1-5: device descriptor read/64, error -71 [19731.728372] usb usb1-port5: attempt power cycle [19732.380247] usb 1-5: new full-speed USB device number 9 using xhci_hcd [19732.380409] usb 1-5: Device not responding to setup address.

I have tried the "#define USB_FORCE_DISCONNECT 1" in the board.h file, but I get the same message.

I am flashing to address 0x08000000, which is where I believe it starts execution from. Here is my flash command: sudo st-flash write bootloader.bin 0x08000000

Here is the STM32 wiki page for this board: https://stm32-base.org/boards/STM32F411CEU6-WeAct-Black-Pill-V2.0.html

The wiki page does describe extra connections made to D+ and D-: Pin | Function | Connected to B7 | D- | PA11 via 10Ω (R9) A6 | D+ | PA12 via 10Ω (R7) A7 | D- | PA11 via 10Ω (R9) B6 | D+ | PA12 via 10Ω (R7)

Any ideas would be appreciated.

I am able to program the board to a TinyUSB device without any issues. I have been able to do several of the example devices and they are detected by the OS reliably.

The resistors shouldn't make a difference.

If you're not trying to build a MakeCode Arcade device, I suggest you try https://github.com/adafruit/tinyuf2 instead of this repo.

Thank you for the suggestion. I will use that project.
