Hi everyone and I’m looking for help.  
I’ve been creating my simple code running on pixhawk 6C mini FC since it has sensors integrated. However, things gone bad recently. I started a debug session using gdb and ST-Link provided by STM32CubeCLT, and after I put a breakpoint inside, everything just stuck and I can’t stop STM32H743 anymore (with an error saying DEV\_TARGET\_NOT\_HALTED).

I browsed the Internet and found that entering DFU mode and program the chip using USB DFU could help. I only found BOOT0 for pixhawk 6C, not mini.  
Help wanted and thanks a lot.
