开发环境

开发环境：ubuntu18

一、选择型号

板级配置	说明
BoardConfig-rk3566-evb2-lp4x-v10-32bit.mk	适用于 RK3566 EVB 搭配 LPDDR4 开发板，运行32位根文件系统
BoardConfig-rk3566-evb2-lp4x-v10.mk	适用于 RK3566 EVB 搭配 LPDDR4 开发板
BoardConfig-rk3568-evb1-ddr4-v10-32bit.mk	适用于 RK3568 EVB 搭配 LPDDR4 开发板，运行32位根文件系统
BoardConfig-rk3568-evb1-ddr4-v10-spi-nor-64M.mk	适用于 RK3568 EVB 搭配 DDR4/SPI NOR 开发板
BoardConfig-rk3568-evb1-ddr4-v10.mk	适用于 RK3568 EVB 搭配 DDR4 开发板
BoardConfig-rk3568-nvr-spi-nand.mk	适用于 RK3568 NVR 搭配SPI NAND 开发板
BoardConfig-rk3568-nvr.mk	适用于 RK3568 NVR 开发板
BoardConfig-rk3568-uvc-evb1-ddr4-v10.mk	适用于 RK3568 UVC 开发板
BoardConfig.mk	默认配置

根据开发板型号，在SDK根目录执行 ./build.sh lunch ，选择对应的型号，在这里我选择的是 5

qiuwenxiong@Avd-System-Builder:~/rockchip/rk3568x_linux$ ./build.sh lunch
processing option: lunch

You're building on Linux
Lunch menu...pick a combo:

0. default BoardConfig.mk
1. BoardConfig-rk3566-evb2-lp4x-v10-32bit.mk
2. BoardConfig-rk3566-evb2-lp4x-v10.mk
3. BoardConfig-rk3568-evb1-ddr4-v10-32bit.mk
4. BoardConfig-rk3568-evb1-ddr4-v10-spi-nor-64M.mk
5. BoardConfig-rk3568-evb1-ddr4-v10.mk
6. BoardConfig-rk3568-nvr-spi-nand.mk
7. BoardConfig-rk3568-nvr.mk
8. BoardConfig-rk3568-uvc-evb1-ddr4-v10.mk
9. BoardConfig.mk
Which would you like? [0]: 5

二、全自动编译

直接执行 ./build.sh 编译并且打包成固件

./build.sh all           # 只编译模块代码（u-Boot，kernel，Rootfs，Recovery）
                         # 需要再执行./mkfirmware.sh 进行固件打包
                         
./build.sh               # 在./build.sh all基础上
                         # 1. 增加固件打包 ./mkfirmware.sh
                         # 2. update.img打包
                         # 3. 复制rockdev目录下的固件到IMAGE/***_RELEASE_TEST/IMAGES目录
                         # 4. 保存各个模块的补丁到IMAGE/***_RELEASE_TEST/PATCHES目录
                         # 注：./build.sh 和 ./build.sh allsave 命令一样

三、IO电源选择

根据硬件的实际IO电压来选择，我这里全部都是选择 3.3V

三、编译命令详解

qiuwenxiong@Avd-System-Builder:~/rockchip/rk3568x_linux$ ./build.sh -help
Usage: build.sh [OPTIONS]
Available options:
BoardConfig*.mk    -switch to specified board config
lunch              -list current SDK boards and switch to specified board config
uboot              -build uboot
spl                -build spl
loader             -build loader
kernel             -build kernel
modules            -build kernel modules
toolchain          -build toolchain
rootfs             -build default rootfs, currently build buildroot as default
buildroot          -build buildroot rootfs
ramboot            -build ramboot image
multi-npu_boot     -build boot image for multi-npu board
yocto              -build yocto rootfs

updateimg          -pack update image
otapackage         -pack ab update otapackage image (update_ota.img)
sdpackage          -pack update sdcard package image (update_sdcard.img)
save               -save images, patches, commands used to debug
allsave            -build all & firmware & updateimg & save
check              -check the environment of building

Default option is 'allsave'.

五、各模块编译

1、U-boot编译

./build.sh uboot

2、Kernel编译

./build.sh kernel

3、Recovery编译

./build.sh recovery

注：Recovery是非必需的功能，有些板级配置不会设置
