We have experienced the issue referenced in this thread on both the commercial and industrial Xavier models:
The patch provided in that thread works for our commercial modules, but for the industrial models there seems to be no corresponding dtsi file for the patch in the hardware/nvidia/platform/t19x/galen/kernel-dts/common directory.
To get the sources I ran source_sync.sh -t tegra-l4t-r32.6.1, but after that there is no result when looking for files named tegra194-p2888-0008*; I would have guessed there would be something along those lines to apply a similar patch to?
Also, can you verify that in your kernel building instructions where in step 6 you say to “Replace the contents of Linux_for_Tegra/kernel/dtb/ with the contents of $TEGRA_KERNEL_OUT/arch/arm64/boot/dts/”, this means I should remove the contents of Linux_for_Tegra/kernel/dtb/ before copying the build products into it? I have seen other examples online of people just overwriting/adding files instead of doing a wholesale replacement.
