Ensuring a Working RK809 Link
To establish a reliable RK809 working link, a methodical approach is recommended:
* Verify Hardware Connections: Double-check all physical connections according to the RK809 Power Diagram and relevant datasheets`dailink-multicodecs` detected instead of `fe410000.i2s-
* Validate Device Tree: Ensure the RK809 is correctly defined in the device tree, with accurate properties for regulators, codecs, and power controls[v1] dt-bindings rockchip Add support for rk809 audio codec Referencing relevant entries like `rockchip,rk809TheRK809-1 is a custom electronic component manufactured by Rockchip.
