Hello, I have a problem. Execute ./source_sync.sh -k tegra-l4t-r28.1 implementation is complete, why in the sources / kernel / kernel-4.4 / arch / arm64 / boot / dts / directory without your company’s device tree file?
These are provided, but there was a segregation into different directories. R28.1 is the release where both TX1 and TX2 finally use the same release, so I suppose this was the motivation (device trees differ between a TX1 and TX2, perhaps it was easier this way). You’ll see that a source_sync.sh download has top level directory “sources/”, and if you go the “hardware/nvidia/platform/t18x/quill/kernel-dts/” subdirectory, the device tree for the t18x (TX2) will be there.
The Documentation download with R28.1 gives some information on building, and you will find this works with the source_sync.sh version.
