I connect the PB9-BOOT0 to VDD, then power up the board, but it just run from flash(application program), not the bootloader, what's the matter?
I am not firmilar with ISP, I suppose it should enter bootloader, and wait for ISP program to communicate.
I want to confirm, besides connect PB9-BOOT0 to VDD, is there any other thing need be done?
