uboot 、kernel 编译

15.4.3 编译u-boot v2014.10

本节内容适用于如下OS:

lubuntu

eflasher

friendlydesktop-arm64

friendlycore-arm64

下载源代码并编译:

git clone https://github.com/friendlyarm/uboot-rockchip --single-branch --depth 1 -b nanopi4-v2014.10_oreo
cd uboot-rockchip
export PATH=/opt/FriendlyARM/toolchain/6.4-aarch64/bin/:$PATH
make CROSS_COMPILE=aarch64-linux-gnu- rk3399_defconfig
make CROSS_COMPILE=aarch64-linux-gnu-

编译完成后会生成如下文件:

uboot.img

trust.img

rk3399_loader_v1.22.119.bin (打包时改名为MiniLoaderAll.bin)

安装u-boot:

 

 

15.4.2 编译内核linux-v4.4.y

本节内容适用于如下OS:

lubuntu

eflasher

friendlydesktop-arm64

friendlycore-arm64

下载源代码并编译:

git clone https://github.com/friendlyarm/kernel-rockchip --single-branch --depth 1 -b nanopi4-linux-v4.4.y kernel-rockchip
cd kernel-rockchip
export PATH=/opt/FriendlyARM/toolchain/6.4-aarch64/bin/:$PATH
touch .scmversion
# 配置内核
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- nanopi4_linux_defconfig
# 启动配置界面
# make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- menuconfig
# 编译内核
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- nanopi4-images -j$(nproc)
# 编译驱动模块
mkdir -p out-modules
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- INSTALL_MOD_PATH="$PWD/out-modules" modules -j$(nproc)
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- INSTALL_MOD_PATH="$PWD/out-modules" modules_install
KERNEL_VER=$(make CROSS_COMPILE=aarch64-linux-gnu- ARCH=arm64 kernelrelease)
rm -rf $PWD/out-modules/lib/modules/${KERNEL_VER}/kernel/drivers/gpu/arm/mali400/
[ ! -f "$PWD/out-modules/lib/modules/${KERNEL_VER}/modules.dep" ] && depmod -b $PWD/out-modules -E Module.symvers -F System.map -w ${KERNEL_VER}
(cd $PWD/out-modules && find . -name \*.ko | xargs aarch64-linux-strip --strip-unneeded)

编译完会生成如下文件:

kernel.img

resource.img

驱动模块位于out-modules目录
