    我的编译步骤

    export PATH=/home/panston/ti-processor-sdk-linux-am335x-evm-03.00.00.04/linux-devkit/sysroots/x86_64-arago-linux/usr/bin:$PATH

    make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- distclean

    make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- tisdk_am335x-evm_defconfig

    make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- menuconfig
    make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- zImage -j 4
    make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- am335x-icev2.dtb
    make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- modules -j 4
    cp arch/arm/boot/zImage /media/panston/rootfs/boot/
    cp arch/arm/boot/dts/am335x-icev2.dtb /media/panston/rootfs/boot/
    cp arch/arm/boot/dts/am335x-icev2.dtb /media/panston/boot/
    make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- INSTALL_MOD_PATH=/media/panston/rootfs modules_install

    bootargs 没有动    串口3 启动是还有信息输出   直到文件系统启动来后就无法输入 很无奈呀
