STM32H7 program does not start when powered on

[mertt]

Hello,

I am using STM32H733 mounted on a custom PCB. The problem is that if I power the board on, the program inside the MCU does not start.

 

The programming is done over the JTAG/SWD interface. After programming, the code is able to start running.

However, after power on, I need to push the reset button (reset circuit, nRST) to run the software, otherwise the code does not start.

 

Where can be the problem? Any help would be appreciated.

 

Thanks in advance.

Best regards,

Mert

Is BOOT0 pulled low?

That was a assembly issue. The problem is solved.

Thank you.

Best regards,
