I'm programming two cards. The first has a STM32F205RG, this one functions perfectly, I can program it and do what I want (I'm using SWD connection to program my cards).
The second one has a STM32F429IG. For this one, I cannot program it. I have tried with J-LINK, ST LINK (by using IAR or ST LINK utility). The connection diagram is exactly the same as for the first board, and I have also checked all connections between connector and µC.
In enclosed documents, my main connections (PDR_ON and BYPASS_REG are not connected, I have also tried to connect them to VDD but it's the same).
If you have any suggestions (diagram, option in IAR/ST LINK), I'll be very happy.
