First time on the forum. I have to say I’m very intrigued by platformIO and I hope someone will be able to spot what I’m doing wrong.
I have a black pill board with the STM32F411CEU6 and I’m trying to flash it using an STlink looking like this:
I have been trying a few different configurations that look like this:
[env:blackpill_f411ce]
platform = ststm32
board = blackpill_f411ce
extra_scripts = undefined_exit.py
; change microcontroller
board_build.mcu = stm32f411ceu6
; change MCU frequency
board_build.f_cpu = 100000000L
build_flags = -v
[env:genericSTM32F411CE]
platform = ststm32
board = genericSTM32F411CE
upload_protocol=stlink
extra_scripts = undefined_exit.py
; change microcontroller
board_build.mcu = stm32f411ceu6
; change MCU frequency
board_build.f_cpu = 100000000L
I execute with the command like this
platformio run -eblackpill_f411ce -t upload
And it doesn’t matter which of the configurations I use it gives me the same problem:

The program I’m trying to flash is just an empty and infinite while loop.
I should also say this is my first time using anything STM or platformIO so I feel like I must have missed something simple but I can’t quite see what. I’ll be happy to do my best to provide further information or logs. Any tips on what I can try is helpful.
This is my test setup to learn how to program stm32 chips as I have a custom PCB ordered for assembly and coming in a few weeks.
