Part Number: PROCESSOR-SDK-AM65X

Hello,

I am using the latest pin-mux tool for generating the pin-mux files online. The tool generates four files:

1. AM65xx_pinmux.h

2. AM65xx_pinmux_data.c

3. devicetree.dtsi

4. PinmuxConfigSummary.csv

I am working on the linux sdk. How should i use these files in the kernel to successfully complete the pin configuration?

For AM654x you should use the configurations presented in devicetree.dtsi file. However you cannot use the file as is. You should add the pinmuxing you need in u-boot & linux kernel.

For u-boot pinmuxing is done in arch/arm/dts/k3-am654-base-board.dts and arch/arm/dts/k3-am654-r5-base-board.dts.

For Linux you should do additional pinmux used by the kernel, this is done in arch/arm64/boot/dts/ti/k3-am654-base-board.dts and respectively in the overlay files: k3-am654-gp.dtso or k3-am654-idk.dtso depending on which board are you using.

Best Regards,
