How to add kernel args when compiling linux kernel?

I followed intructions in this project, but I couldn't figure out how to add "console=ttyAMA0,115200 panic=5" to kernel args. Anyone knows how to add this kernel args?

Solution

  • Open defconfig

    vim ./arch/arm/configs/vexpress_defconfig

    change this

    CONFIG_CMDLINE="console=ttyAMA0"

    to this

    CONFIG_CMDLINE="console=ttyAMA0,115200 panic=5"
