I’m trying to create a new airframe with custom code for the mixers. I found where to add my new mixer class and get it to compile. I created a mixer file and a config file based on existing files and downloaded everything using QGC. Looking on the bootloader.txt file in the sd card shows that my custom mix file doesn’t exist. I tried placing it in etc/mixers and it still says it can’t find it. I’ve tried going through the docs multiple times and I still can’t seem to get everything to work or get placed properly. Can someone please provide a complete example of where to put files, download, etc. It is very confusing how all this goes together. Also a good config example would help. I may be missing a process. I’m building it using "make px4fmu-v3_default since I have a Pixhawk 2 (cube).
Thank you very much for everyones time.
