I am using STM32F070F6P6 with my own board, and I have the following issue: When I start debug session in Keil run button is something like already pressed and when I stop the execution the PC is at address 0x1FFFCAC4. The program never enter main.

I use Cube MX to configure pins and peripherals.

I think that is board issue but I can't find the reason.

Thanks

Running from ROM, make sure BOOT(0) pin is pulled LOW to run from FLASH, check option-bytes on chips without BOOT pins.
