Hello everyone, I'm working on STM32H747i-disco. I use st-utility to flash a binary file from DSPC(audioweaver) but it's taking a very long time 36 mns. I already flash anothers binaries files and its work well but not for DSPC binary.

Do you think it could be a jumper problem? Thanks

Does the firmware program external flash? Flashing internal flash should happen in some 10 seconds. How big is th DSPC (whatever that is) binary.

Hi Uwe,

Thanks for your prompt reply. No its for internal flash. File is 1.1 Mbytes. The flash of stm32H747i is 2Mbytes size.
