DFU mode STM32H7B3

MMarco · ‎2025-04-15

Hello,

we are facing some problem entering DFU mode from application code on our custom boards equipped with STM32H7B3 with bootloader release 0x92.

On contrary, everything works fine with same board equipped with STM32H7B3 bootloader release 0x91.

Beside the notes on AN2606 related to bootloader history, can someone from ST point out if are there any other changes on bootloader that can cause this strange behaviour?

Thanks,
