Problem Building 28.1 from source

I have not been able to build l4t 28.1 for the TX2 from from source archive provided in the download center.

Multiple files are missing, without any changes I get the following error:

/Linux_for_Tegra/sources/kernel/kernel-4.4/include/linux/platform/tegra/mc.h:28:47: fatal error: linux/platform/tegra/mc-regs-t18x.h: No such file or directory
#include <linux/platform/tegra/mc-regs-t18x.h>

Adding the missing from a 27.1 branch clears this error but then there are several more files missing as well.

I cannot sync with the Git as the tags are not there for 28.1.

I also cannot use Jetpack 3.1 to download it as I always get an error when running it.

Looks like the source code provided with this release is wrong. Many key files are missing.

The t18x source in the kernel_src tarball issue has been root caused and resolved, those files have been added to the source tarball, please download it again from the link:


I updated my kernel make tool to work with this new release and posted it to Github if anyone else is still having issues. Also posted some light weight R28.1 file systems more suited to embedded applications.
