PINMUXTOOL: J721e IO configuraiton

Part Number: PINMUXTOOL

We are using J721e Chipset for one of HW. On A72 core we are using Pinmux tool for IO configurations and it is generating device tree for us which we are using in u-boot and Kernel build. However we are not sure how IO mapping works on R5 side. Could you help us understand following –

  • How pinmux tool works for IO configuration for R5 core?
  • When we generate DTS file for A72 core does it also consider the IO mapping for R5 core?

Thanks,

Satish
