Hi,
I have a bug with my bootload application on STM32H743ZI (my device is powered and bootloaded throw the same USB port)
1 - I send a HID USB message to tell the micro to jump to bootloader
2 - I bootload using DfuSe dll (it appears to work fine)
3 - After bootload I don't see my HID device on my PC even after unplug plug device (Perhaps is only the USB Core not working ?)
I want to move from SWD programming to USB DFU programming
I tried using STM32CubeProgrammer software and I got the same result and this logs which again seems to work fine :
