Getting the Sources

Use the tools issued by Nvidia to handle kernel sources via git. Checkout the desired kernel version, probably the newest.

root # wget http://developer.nvidia.com/embedded/dlc/l4t-Jetson-TK1-Driver-Package-R21-5 -O $TOOLS/l4t-Jetson-TK1-Driver-Package-R21-5
root # cd $TOOLS
root # tar jxf l4t-Jetson-TK1-Driver-Package-R21-5
root # rm l4t-Jetson-TK1-Driver-Package-R21-5
root # cd Linux_for_Tegra
root # ./source_sync.sh  #skip tag selection both times
root # cd sources/kernel_source
root # git ls-remote
root # git checkout tegra-l4t-r24.2.1
root # ln -s $PWD $XC_KERNEL_SRC
root # . xcompile_variables.sh
root # git checkout -b `get_kernel_version`

Kernel Building

You need a working kernel config. You can get one from a running TK1 and get it into your $XC_KERNEL_SRC directory.

root # zcat /proc/config.gz > my_TK1_config
root # scp my_TK1_config <xc_user>@<xc_host>:~
root # cp ~/my_TK1_config $XC_KERNEL_OLDCONFIG

Or you can get it from the kernel headers.

root # cd $TOOLS/Linux_for_Tegra/kernel
root # tar xvf kernel_headers.tbz2
root # cp linux-headers-<kernel_version>/.config $XC_KERNEL_OLDCONFIG
