 From 3.15, AC100 finally boots the official mainline kernel !  From 3.15, AC100 finally boots the official mainline kernel ! 
 +To succesfully cross-compile it, i used linaro precompiled toolchain [[http://​releases.linaro.org/​14.05/​components/​toolchain/​binaries/​gcc-linaro-arm-linux-gnueabihf-4.9-2014.05_linux.tar.xz]]:​
 +
 +  wget http://​releases.linaro.org/​14.05/​components/​toolchain/​binaries/​gcc-linaro-arm-linux-gnueabihf-4.9-2014.05_linux.tar.xz
 +
 +extract it somewhere, and export install path so the toolchain can be found:
 +  tar xvf gcc-linaro-arm-linux-gnueabihf-4.9-2014.05_linux.tar.xz ​
 +  export PATH=$PATH:​gcc-linaro-arm-linux-gnueabihf-4.9-2014.05_linux/​bin/​
 +
 +Now you have to clone the kernel git repository:
 +  git clone git://​git.kernel.org/​pub/​scm/​linux/​kernel/​git/​torvalds/​linux.git
 +  cd linux
 +  ​
 +As already described above, configure && make && install and your kernel is ready!
 +  make tegra_defconfig ARCH=arm
 +  make zImage modules dtbs INSTALL_MOD_PATH=/​tmp INSTALL_MOD_STRIP=1 ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-
 +  make modules_install INSTALL_MOD_PATH=/​tmp INSTALL_MOD_STRIP=1 ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-
 +
 +Copy everything you need in a folder (to copy on SD or USB key and put into AC100)
 +  mkdir ~/​linux-3.16-0
 +  mv /tmp/lib/ ~/​linux-3.16-0/​
 +  cp arch/​arm/​boot/​zImage ~/​linux-3.16-0/​
 +  cp arch/​arm/​boot/​dts/​tegra20-paz00.dtb ~/​linux-3.16-0/​
