I have a custom PCB using the STM32F042F. I replaced the STM, and now every time I connect the communication chip, the STM32 turns off. The STM does not boot if I first connect the nRF24L01 then power the STM.
I am confident my code and the board are not the issue, as it was functioning before I replaced the STM32 chip.
I think that some default configuration setting I am missing is causing the boards to short.
Does anyone have any ideas on how I can solve this issue?
