Building Linux kernel for MIPS

  • Get "mips32 musl" cross-compilation toolchain from http://toolchains.free-electrons.com/.

    $ cd ~

$ tar -xjvf mips32--musl--bleeding-edge-2017.05-toolchains-1-2.tar.bz2

  • Build Linux kernel with this toolchain.

    $ cd <kernel-source-tree>

    $ make ARCH=mips CROSS_COMPILE=$HOME/mips32--musl--bleeding-edge/bin/mips-linux- menuconfig

    • Under Machine selection, Select System type (MIPS Malta board)

    • Under Linux Kernel Configuration, Select Endianess selection (Big endian)

    $ make ARCH=mips CROSS_COMPILE=$HOME/mips32--musl--bleeding-edge/bin/mips-linux- -j8

  • Use the generated vmlinux file for booting a MIPS system.
