Second thing, make sure you have clicked options Show All Devices in order to see the STM Bootloader. If this is not done, it will not show the STM Bootloader in Zadig. Or a way to bypass this and still end up where I need to be with Betaflight. Is there a way to get the Bootloader on the devices list on Zadig. I think Im doing most of it right, but Im stuck because on the options list on Zadig doesnt show STM32 Bootloader. Trying to follow the directions from several Youtube videos about this process. This will put the board in dfu mode.Did you know Registration is FREE and is only a couple clicks away You can even sign in from Facebook, Twitter or Google for your convenience So what are you waiting for, CLICK HERE to join in on the conversation.

Hold down the boot button (boot not bind this time) and power on the flight controller. Wait a few seconds and then power off the board. The board will not appear to boot but the flash sector is being erased.

ArduPilot provides support to make this easy. This is a destructive operation requiring complete erasure of the flash. You now must remove the copy protection on the internal flash. You must initially have a working version of ArduPilot installed on the board - follow the steps above. If you are certain that you only want to use ArduPilot on the board, then flashing the ardupilot bootloader enables much simpler subsequent upgrades. You cannot restore the board to factory configuration or load betaflight after this step - you would have to return the board to Seriously Pro to be re-flashed with factory firmware, assuming that is possible Installing the ArduPilot bootloader is a one-way operation. A summary of the steps follows:ĭownload and install SSBL to external flash following ĭownload the latest ArduPilot external flash binary, for instance Once SSBL is loaded please follow the PX4 instructions to load ArduPilot onto the board but instead of using PX4 firmware please use the arducopter.bin firmware image. Please follow the “INSTALLATION” instructions at in order to load SSBL onto your board. There are a couple of options to load firmware with these boards, but whichever option you choose you will need to initially load ArduPilot using SSBL. The SPRacing series of boards come pre-installed with a proprietary bootloader on the internal flash and require the use of a second stage bootloader to load further firmware.
