Hi everybody,

I have a problem with my project. I designed and produced a PCB with two MCUs, the STMF401RB and the STM32F407VGT. I am using the ST-LINK V2 to program them and SWDIO and SWCLK. The problem that I have is that I can connect to the STMF401 but I can't connect to the STMF407. I checked the VDD and VSS in every pin and they seem to be ok. I think the design is ok but may be i missed something. I have attached the schematic that I used for the STMF407. I would be grateful if you can help me.


Thank you very much
