Program uploaded with STLink Utility doesn't run

[JLaub.1]

Hi, this is a newbie kind of question i think.

I have a very simple program, one that blinks a led. I can debug and run from inside STMCube IDE (all works ok), but if i upload the bin file with the STLink Utility (Windows), the program doesn't run. What i'm doing wrong?

Thanks in advance

Is this a custom board? What STM32 part?

Make sure BOOT0 pin is pulled low.

Thanks clive1 for the answer. The board is the DIYMORE STM32F407VGT6. And i was not aware of the need for pulling down BOOT0 (it seems STMCube IDE doesn't need this)
