I followed the Jetson Xavier NX Platform Adaptation and Bring-Up Guide for an own carrier board, but have still some problems.
I customized the pinmux spreadsheet from the Jetson Xavier NX and generated the dtsi files. With the dtsi files I generated a pinmux.cfg and a pad.cfg file. The most important changes in the kernel are the activations of the SD-Card on SDMMC3 and SPI0. I have done that for the Nano with no problems but I cannot find the necessary changes for the Xavier NX (production module). If my assumption is right there must be an entry in the DTSI where I change the SDMMC3 from “disabled” to “okay”. Same for SPI0 I guess.
Could someone please give me some hints how to do this? Any help much appreciated!
