Hi!
First of all I’d like to say that I am fairly new in the world of drone firmware. I am interested to know if there is a place where I check out the Here4 bootloader or if there is any documentation regarding the firmware update over the Ardupilot/Mission Planner. I am mostly interested in the actual firmware update procedure down in the droneCAN layer, meaning what messages are sent to instantiate the firmware update, how the new firmware is being sent, etc. I am implementing a bootloader for a device that will be connected to the autopilot and it would be great to have a reference.
I am using the NXP S32K144 microcontroller.
Thanks in advance!
