Hello,
I made a custom board using the STM32C031K4T6. I have tried several times now to connect to the chip using STM32 Cube IDE and the STM32 Programmer, both didn't work. The ST-Link gets recognized. I have tried different combinations regarding the Boot0 pin and the reset pin but I can't get it to work. I get the error message that no target was found. I also attached the schematic for the board.
Solved! Go to Solution.

Hello,
On your schematic the programmer connector does not provide VDD, so the STLink cannot read the voltage (it says voltage is 0.0V) and if I'm correct it has level converters that need VDD to operate and communicate with the microcontroller.
Best regards.

Thanks, that was the solution. Its a bit sketchy now with the extra cable but I know what to look for in future projects.
Best regards
