Flashing PX4 Bootloader on Non-Standard Pixhawk Autopilots (Holybro Kakute H7)

This was quite a struggle to figure out and I wanted to share the steps to get PX4 running on a Holybro Kakute H7 flight controller. Links can be found here:

Since Betaflight Configurator and dfu-util did not work I ended up going the STM32CubeProgammer route:

A shout out to the ArduPilot community for getting me going:

After running some tests with the Kakute H7 I will be transitioning to run some tests with the Matek H743 Slim board.
