STM32G474CE wont start on debug or after power on.

[ODemi.1]

Hi,

I have a new project with STM32G474CE and cant get it start. If I program it with STM32CubeProgrammer it runs the a simple code for led blinking. I checked all VDD,Vref,Vbat pins and all okay. But after powering it off and on again, code gets stuck.

I debug it with keil and see it is stuck in some loop at the beginning. Same thing happens if I programm it with keil, it cant reach to led blinking.

I checked the option bits with STM32CubeProgrammer for boot0 and it is unchecked.

Sorry. Just figured it out. It is on system memory. Boot conf. is not correct. It is solved.
