I’m porting hwdef.dat file to a new board and getting hard time in understanding its structure in terms of peripheral IO configurations and enabling drivers for different sensors.
Are there any documents available to understand the standards/structure of hwdwf file?
The fmuv3 hwdef file is the most complete and commented file that I know of, if that helps.
And this section in the developer docs https://ardupilot.org/dev/docs/porting.html
I know icm20602 is probed using SPI driver but what is ROTATION_ROLL_180_YAW_270 and some drivers are specified with _ext. These details are not mentioned anywhere
