| + | ===== 3.10.x Kernel series ===== | ||
| + | 3.10 build process is close to 3.0 for-next. | ||
| + | Device-tree is mandatory, you need to build it and concatenate with a kernel: | ||
| + | < | ||
| + | make dtbs | ||
| + | cat arch/ | ||
| + | </ | ||
| + | But 3.10 don't use paz00_defconfig anymore. Instead is uses tegra_defconfig (main idea of device-tree is to have all-in-one kernel and choose drivers on boot time using device-tree): | ||
| + | < | ||
| + | |||
| + | ===== Mainline Git Kernel ===== | ||
| + | From 3.15, AC100 finally boots the official mainline kernel ! | ||
| + | To succesfully cross-compile it, i used linaro precompiled toolchain [[http:// | ||
| + | |||
| + | wget http:// | ||
| + | |||
| + | 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: | ||
| + | |||
| + | Now you have to clone the kernel git repository: | ||
| + | git clone 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=/ | ||
| + | make modules_install INSTALL_MOD_PATH=/ | ||
| + | |||
| + | Copy everything you need in a folder (to copy on SD or USB key and put into AC100) | ||
| + | mkdir ~/ | ||
| + | mv /tmp/lib/ ~/ | ||
| + | cp arch/ | ||
| + | cp arch/ | ||
