I use JumpToBootloader() to jump to bootloader, device enters bootloader and shows device
i then send it this command
dfu-util -d 0483:df11 -S 305737513432 -a 0 -s 0x08000000:leave -D fw.bin
and device resets
Erase [ ] 0% 0 bytesdfu-util: Error during special command "ERASE_PAGE" get_status: -9 (LIBUSB_ERROR_PIPE)
If i enter the bootloader via the BOOT pin it works fine
It is like something else needs to be reset ?
