Hi, I am making a pixhawk based board. I have a stm32f4 but no stm32f1. I don’t know what files to flash and what to do with the px4io_bl.bin as there is no stm32f1 chip. I just want it to run Ardupilot. Hope you all can help me. Thanks
Maybe you can try pixracer.

It can run ardupilot.
I think this is what your looking for. I have been looking at ardrupilot for some time and it looks like night ghost has ported it to the f4 flight controller boards that would normally run cleanflight/betaflight/inav flight.
I am looking forward to test but my go with true ardrupilot hardware as well. New OS free F4Light HAL
