打包ro分割槽, 生成xxx.squashfs-xz

#mksquashfs $ROOTFS_DIR image-ro  -noappend -comp xz

打包rw分割槽，生產xxx.jffs2

#mkdir jffs2
#mkfs.jffs2 --root=jffs2 --faketime --output=image-rw

打包uboot/kernel/ro/rw，生成xxx.static.mtd

dd生成flash大小的檔案，填充ff
#dd if=/dev/zero bs=1k count=$NOR_IMAGE_SIZE | tr '\000' '\377' > $NOR_IMAGE

寫入uboot
#dd bs=1k conv=notrunc seek=$FLASH_UBOOT_OFFSET if=image-uboot of=$NOR_IMAGE

寫入kernel
#dd bs=1k conv=notrunc seek=$FLASH_KERNEL_OFFSET if=image-kernel of=$NOR_IMAGE

寫入ro
#dd bs=1k conv=notrunc seek=$FLASH_ROFS_OFFSET if=image-ro of=$NOR_IMAGE

寫入rw
#dd bs=1k conv=notrunc seek=$FLASH_RWFS_OFFSET if=image-rw of=$NOR_IMAGE

 

生成升級用的tar包

根據static.mtd生成tar包

• 收集檔案:image-bmc(xxx.static.mtd), MANIFEST, publickey
• 對上述檔案簽名

signature_files=""
for file in "image-bmc MANIFEST publickey"; do
    openssl dgst -sha256 -sign ${private_key} -out "${file}.sig" $file
    signature_files="${signature_files} ${file}.sig"
done

• 對所有簽名檔案簽名

cat $sort_signature_files > image-full
openssl dgst -sha256 -sign ${private_key} -out image-full.sig image-full
signature_files="${signature_files} image-full.sig"

• 打包

tar -h -cvf $OUTPUT image-bmc MANIFEST publickey ${signature_files}
