Hello,
I'm just developing upgrade path of my custom STM32F767 device. I can enter stock bootloader with boot0 pin+reset as well from software jump. It works fine, programs flash and option bytes.
The problem arises when I'm trying to program protected device (level 1). It boots into bootloader then DfuSe reports that device has protection lock. Then DfuSe ask if I want to unlock device, which is also fine. However during unlocking DfuSe seems to freeze (just after issuing unlock command at 0% download).
After this device stays unlocked with blank flash. I've tried latest DfuSe 3.0.6 and previous 3.0.5. Both behave same way - freeze after unlock at 0%.
Any hint or solution?
best regards
Mikolaj Tutak
