Configuration file introduction

The configuration file is in the device/rockchip/rk3399目录下
myzr-rk3399.mk compile ubuntu image
myzr-rk3399-buildroot.mk compile buildroot image

The configuration file has several important attributes:

• Compile u-boot configuration file

export RK_UBOOT_DEFCONFIG=myzr-rk3399

• Compile the kernel configuration file

export RK_KERNEL_DEFCONFIG=myzr_linux_defconfig

• Compile kernel device tree

export RK_KERNEL_DTS=rk3399-myzr-hdmi

• Partition information

export RK_PARAMETER=parameter-ubuntu.txt

• Root file system mirror path

export RK_ROOTFS_IMG=system/system.img

Compile ubuntu image

• Set up a profile

$./build.sh myzr-rk3399.mk
