After referring to [FAQ] TDA4VM: How to modify pinmux using Board_init() in board library - Processors forum - Processors - TI E2E support forums, I reorganized and planned the pinmux. However, after entering the system, the pinmux of some pins did not match what I set in the device tree. The current board is based on j721e-evm. There are four syscfg files in the board folder, but only one was modified in the tutorial. I don't know if it is related to the other three.
Although I also modified the remaining three and removed the related devices, the pinmux still has errors. What is the problem?
