Titan固件

安装依赖
```
apt-get -y install zip
```

拷贝固件依赖的文件

export TMP=pack_dir
mkdir -p $TMP/factory/
cp $TARGET_ROOTFS/usr/lib/u-boot/spacemit/bootinfo_emmc.bin $TMP/factory
cp $TARGET_ROOTFS/usr/lib/u-boot/spacemit/bootinfo_sd.bin $TMP/factory
cp $TARGET_ROOTFS/usr/lib/u-boot/spacemit/bootinfo_spinand.bin $TMP/factory
cp $TARGET_ROOTFS/usr/lib/u-boot/spacemit/bootinfo_spinor.bin $TMP/factory
cp $TARGET_ROOTFS/usr/lib/u-boot/spacemit/FSBL.bin $TMP/factory
cp $TARGET_ROOTFS/usr/lib/u-boot/spacemit/u-boot.itb $TMP
cp $TARGET_ROOTFS/usr/lib/u-boot/spacemit/env.bin $TMP
cp $TARGET_ROOTFS/usr/lib/riscv64-linux-gnu/opensbi/generic/fw_dynamic.itb $TMP
cp bootfs.ext4 $TMP
cp rootfs.ext4 $TMP

下载参考分区表

wget -P $TMP https://gitee.com/bianbu/firmware-config/raw/main/fastboot.yaml
wget -P $TMP https://gitee.com/bianbu/firmware-config/raw/main/partition_2M.json
wget -P $TMP https://gitee.com/bianbu/firmware-config/raw/main/partition_flash.json
wget -P $TMP https://gitee.com/bianbu/firmware-config/raw/main/partition_universal.json

打包
```
cd $TMP
zip -r ../bianbu-custom.zip *
```

SDCARD镜像

下面介绍如何使用genimage制作SDCARD镜像。

安装依赖

echo 'tzdata tzdata/Areas select Asia' | debconf-set-selections
echo 'tzdata tzdata/Zones/Asia select Shanghai' | debconf-set-selections
DEBIAN_FRONTEND=noninteractive apt-get -y install wget python3 genimage

拷贝固件依赖的文件

export TMP=pack_dir
mkdir -p $TMP/factory/
cp $TARGET_ROOTFS/usr/lib/u-boot/spacemit/bootinfo_emmc.bin $TMP/factory
cp $TARGET_ROOTFS/usr/lib/u-boot/spacemit/bootinfo_sd.bin $TMP/factory
cp $TARGET_ROOTFS/usr/lib/u-boot/spacemit/bootinfo_spinand.bin $TMP/factory
cp $TARGET_ROOTFS/usr/lib/u-boot/spacemit/bootinfo_spinor.bin $TMP/factory
cp $TARGET_ROOTFS/usr/lib/u-boot/spacemit/FSBL.bin $TMP/factory
cp $TARGET_ROOTFS/usr/lib/u-boot/spacemit/u-boot.itb $TMP
cp $TARGET_ROOTFS/usr/lib/u-boot/spacemit/env.bin $TMP
cp $TARGET_ROOTFS/usr/lib/riscv64-linux-gnu/opensbi/generic/fw_dynamic.itb $TMP
cp bootfs.ext4 $TMP
cp rootfs.ext4 $TMP

下载参考分区表

wget -P $TMP https://gitee.com/bianbu/firmware-config/raw/main/partition_universal.json

下载生成genimage.cfg的脚本，并生成genimage.cfg

wget -P $TMP https://gitee.com/bianbu-linux/scripts/raw/bl-v1.0.y/gen_imgcfg.py
python3 $TMP/gen_imgcfg.py -i $TMP/partition_universal.json -n bianbu-custom.sdcard -o $TMP/genimage.cfg

生成SDCARD镜像

ROOTPATH_TMP="$(mktemp -d)"
GENIMAGE_TMP="$(mktemp -d)"
genimage \
    --config "$TMP/genimage.cfg" \
    --rootpath "$ROOTPATH_TMP" \
    --tmppath "$GENIMAGE_TMP" \
    --inputpath "$TMP" \
    --outputpath "."

当看到以下信息时，说明打包成功。
