RK3568开发板安卓系统之驱动调试技巧（三）

3 调试技巧分享

3.1 单独编译u-boot

hale@thinkpad:rk3568_aybering_Android11$ cd u-boot
hale@thinkpad:rk3568_aybering_Android11$ ./make.sh rk3568

编译成功后烧写u-boot/uboot.img和rockdev/Image-rk3568_aybering/parameter.txt 即可

3.2 单独编译kernel

hale@thinkpad:rk3568_aybering_Android11$ cd kernel
hale@thinkpad:kernel$ make ARCH=arm64 rockchip_defconfig rk356x_evb.config android-11.config
hale@thinkpad:kernel$ make ARCH=arm64 BOOT_IMG=../rockdev/Image-rk3568_aybering/boot.img rk3568-aybering.img -j`nproc`

编译成功后烧写kernel/boot.img和rockdev/Image-rk3568_aybering/parameter.txt 即可
BOOT_IMG=../rockdev/Image-rk3568_aybering/boot.img必须准确，否则不能正常启动android。

3.3 打包update.img

hale@thinkpad:rk3568_aybering_Android11$ ./build.sh -u

build.sh参数说明

usage()
{
   echo "USAGE: [-U] [-CK] [-A] [-p] [-o] [-u] [-v VERSION_NAME]  "
    echo "No ARGS means use default build option                  "
    echo "WHERE: -U = build uboot                                 "
    echo "       -C = build kernel with Clang                     "
    echo "       -K = build kernel                                "
    echo "       -A = build android                               "
    echo "       -p = will build packaging in IMAGE      "
    echo "       -o = build OTA package                           "
    echo "       -u = build update.img                            "
    echo "       -v = build android with 'user' or 'userdebug'    "
    echo "       -d = huild kernel dts name    "
    echo "       -V = build version    "
    echo "       -J = build jobs    "
    exit 1
