STM32H735-DK reset

I have a demoboard STM32H735-DK. I develop a demo for my customer. All OK. But when I supply the card (with USB cable) the application-firmware doesn't run: I have to press the button reset for start it. Why? Thanks for your answer.

Check jumper and switch settings. Make sure it boots from Flash

Check Option Bytes for Boot Address.

On the code side, make sure you don't have any critical loops related to speed of start up, ie timeouts and ErrorHandler() which might differ if the power is already up and steady vs ramping
