linux开发笔记（buildroot打包镜像）

参考文章:https://www.cnblogs.com/arnoldlu/p/9553995.html

mangopi_r3的buildroot在编译完成后会将所有镜像打包到一起。与之有关的buildroot配置项为

BR2_ROOTFS_POST_IMAGE_SCRIPT="board/allwinner/generic/scripts/genimage.sh"

genimage.sh内容如下

#!/bin/bash
set -e
STARTDIR=`pwd`
SELFDIR=`dirname \`realpath ${0}\``
MKIMAGE="${HOST_DIR}/bin/mkimage"
IMAGE_ITS="kernel.its"
OUTPUT_NAME="kernel.itb"

[ $# -eq 2 ] || {
    echo "SYNTAX: $0 <output dir> <u-boot-with-spl image>"
    echo "Given: $@"
    exit 1
}

cp board/allwinner/generic/kernel.its "${BINARIES_DIR}"
cd "${BINARIES_DIR}"
"${MKIMAGE}" -f ${IMAGE_ITS} ${OUTPUT_NAME}
rm ${IMAGE_ITS}

cd "${SELFDIR}/../"
cp splash.bmp "${BINARIES_DIR}/"

cd "${STARTDIR}/"
