Hello,
I have an expansion board X-NUCLEO-PLC01A1 that I use with a micro controller F767Zi on its F767Zi Nucleo Board.
When I plug the PLC01A1 on the board, I cannot flash (meaning that I can neither Run nor Debug) any code on the micro controller, even if I turn off the 24V supply of the PLC01A1.
I get this error on STM32CubeIDE:
And here is what happens when I try to connect the board on STM32CubeProgrammer with the PLC01A1 plugged on it:
My solution for now is to physically unplug the PLC01A1 every time I have to flash some code on the F767Zi, and then plug it again. Which is not so convenient.
I think this problem can be due to a lack of power from the board which cannot supply itself and the PLC01A1.
Note that even if the 24V power supply of the PLC01A1 is turned off, the PLC01A1 is stilled supplied by the 5V and/or 3.3V pin of the Nucleo Board.
Have any of you an idea to solve this ?
Thank you
