stm32f411ve_discovery (STM32F11E-DISCO) board build broken

[dhalbert]

The stm32f411ve_discovery board build does not come up. I tested older versions: 5.0.0 work, but 6.3.0 and later do not. I tried making a few changes in the build to match the blackpill build more, but did not succeed.

See https://forums.adafruit.com/viewtopic.php?t=218381 for some background.

The board cannot be powered just from the OTG (micro-USB) port. Voltage must be supplied at the mini-USB ST-LINK port. Maybe there's a way to jumper around this.

To load CircuitPython, you can use STM32Cube, but you may need to update the ST/LINK firmware. Getting the board into DFU mode to load via dfu-util to the OTG port is not easy. You must connect Boot0 to VDD< and you must also connect PB2 to ground. See https://community.st.com/t5/stm32-mcus-embedded-software/stm32f411e-disco-dfu-issues/m-p/399415.
