编译固件

1.选择板级配置文件​

进入 SDK 包根目录，执行以下指令：

./build.sh lunch

选择 100ask_rk3568_defconfig

ubuntu@ubuntu2004:~/rk3568_linux5.10_sdk$ ./build.sh lunch
Pick a defconfig:

1. rockchip_defconfig
2. 100ask_rk3568_defconfig
3. rockchip_rk3566_evb2_lp4x_v10_32bit_defconfig
4. rockchip_rk3566_evb2_lp4x_v10_defconfig
5. rockchip_rk3568_evb1_ddr4_v10_32bit_defconfig
6. rockchip_rk3568_evb1_ddr4_v10_defconfig
7. rockchip_rk3568_uvc_evb1_ddr4_v10_defconfig

2.编译​

在当前目录下，执行编译所有：

./build.sh

这个过程耗时较长，具体多久，根据电脑性能决定。

在编译过程，可能你会遇到一下界面，

image-20241231112028411

这里需要选择相应的电压，根据以下电压设置进行选择，

&pmu_io_domains {
        status = "okay";
        pmuio2-supply = <&vcc3v3_pmu>;
        vccio1-supply = <&vccio_acodec>; /*3v3*/
        vccio3-supply = <&vccio_sd>;     /*3v3*/
        vccio4-supply = <&vcc_1v8>;
        vccio5-supply = <&vcc_3v3>;
        vccio6-supply = <&vcc_1v8>;
        vccio7-supply = <&vcc_3v3>;
};

如果电压值选择不正确，会提示编译错误。

3.打包固件​

编译时长较久，等待编译完成后，SDK会自动把用于烧录的镜像 update.img 打包到 output/update/Image/ 下，

如下：

ubuntu@ubuntu2004:~/rk3568_linux5.10_sdk/output/update/Image$ ls -lah
