Hello!
I just received my disco kit with the STM32WBA55CG on board, and I am facing extremely weird behavior.
ST-LINK loses connection to the target during code execution in both debug and non-debug mode. After that, I am no longer capable of connecting to the target and uploading new code/starting debugging.
The only thing I can do is to hold the reset button on the board and connect with STMCubeProgrammer, reset flash and then upload something else.
There are basically two problems:
- Hardware reset on ST-Link does not work (I should do that manually)
- Random disconnects from the target. It should not happen even after a hard fault. And here it is happening constantly
I don't understand if this is a problem with software or settings, and I can fix it fast. Or is the board faulty? I just don't want to waste time debugging.
Should I just return it?
P.S. The funny thing is that I have been using STM MCUs for a decade and tons of projects. However, I never had a DISCO board from them; starting from my very first project with STM MCUs, I used only self-designed boards. And I never had any problems with that. This is my first time buying a disco board to save time while waiting for the custom design. And I got this... I was expecting everything to work out of the box.
