5.2 kernle开发 - 构建脚本

SS928 kernel 提供了 makefile 用于 kernel 构建。
想要得到最后的内核镜像，还要经过许多步骤，每次都手敲命令的话，会把我累死。
自己实现一个构建脚本，支持以下常用功能即可：
- 构建内核镜像
- 配置 kernel
- 清理所有的编译产物

构建脚本

创建脚本：

cd ~/hiss928/kernel/ss928_kernel_v4.19/
touch build.sh
chmod a+x build.sh

脚本内容如下：

#!/bin/bashCUR_PATH=$(pwd)
# 编译产物输出目录
OUTPUT_PATH=${CUR_PATH}/outputHI_ARCH=arm64
# 默认使用的配置文件
HI_DEFCONFIG=ss928v100_emmc
# 使用的工具链
TOOLCHAIN_PREFIX=aarch64-mix210-linux-print_help() {echo "Usage: $0 [OTIONS] COMMAND"echo ""echo "Options:"echo "  -h  show this message and exit"echo ""echo "Commands:"echo "  -m show menuconfig"echo "  -c clean all"
}info() {echo -e "\033[32m"$1"\033[0m";
}error() {echo -e "\033[31m"$1"\033[0m";
}build_kernel() {echo "============Start build kernel============"echo "ARCH   = ${HI_ARCH}"echo "CONFIG = ${HI_DEFCONFIG}_defconfig"echo "=========================================="# 编译 uImagemake ARCH=${HI_ARCH} CROSS_COMPILE=${TOOLCHAIN_PREFIX} ${HI_DEFCONFIG}_defconfigmake ARCH=${HI_ARCH} CROSS_COMPILE=${TOOLCHAIN_PREFIX} -j16 uImageif [ ! -f arch/arm64/boot/uImage ]; thenerror "*** build uImage failed"exit 1;fi# 生成 fip.binmake -C atf PLAT=ss928v100 DEBUG=1 CROSS_COMPILE=${TOOLCHAIN_PREFIX} distcleanmake -C atf PLAT=ss928v100 SPD=none BL33=../arch/arm64/boot/uImage CCI_UP=0 DEBUG=0 \BL33_SEC=0 HISILICON=1 CROSS_COMPILE=aarch64-mix210-linux- fipif [ ! -f atf/build/ss928v100/release/fip.bin ]; thenerror "*** build fip.bin failed"exit 1;fi# 拷贝 kernel 镜像至 output 目录test -d ${OUTPUT_PATH} || mkdir -p ${OUTPUT_PATH}cp -f atf/build/ss928v100/release/fip.bin ${OUTPUT_PATH}/kernel
