I am building a PCB board that have two MCUs STM32, one STM32 for main PX4 firmware, and one lighter STM32 for coprocessor (I assume to be px4io)
My question is, I follow the documentation on Building PX4 Software | PX4 Guide (main) , but that’s only for the px4 firmware on the main STM32, correct? How should I build the firmware for the co-processor?
My other question is, how do I flash those firmwares to the MCUs. What are the best ways to do it?
