生成系统分区镜像在qsdk\meta-tools目录下执行下面脚本生成不同的分区镜像

# --arch   架构 例如 ipq60xx ipq807x
# --fltype 存储类型例如 nor、nand、emmc、norplusnand、norplusemmc
# --in     Output directory where all individual images are copied for single image packing

# NOR 输出镜像路径为：common/build/ipq/nor-system-partition-ipq6018.bin
python prepareSingleImage.py --arch ipq60xx --fltype nor --genpart
--in /images/ipq

# NAND 输出镜像路径为：common/build/ipq/nand-system-partition-ipq6018.bin
python prepareSingleImage.py --arch ipq60xx --fltype nand --genpart
--in /images/ipq

# NOR+NAND 输出镜像路径为：common/build/ipq/norplusnand-system-partition-ipq6018.bin
python prepareSingleImage.py --arch ipq60xx --fltype norplusnand --genpart
--in /images/ipq

# NOR+emmc 输出镜像路径为：common/build/ipq/norplusemmc-system-partition-ipq6018.bin
python prepareSingleImage.py --arch ipq60xx --fltype norplusemmc --genpart

- openwrt-ipq-ipq60xx-qcom-ipq6018-cp03-c1-fit-uImage.itb

上面一步是生成的内核和单个的dtb的镜像，下面生成内核和所有dtb的镜像

生成its文件 gzip格式压缩，用-d 指定多个dtb文件生成fit-qcom-ipq60xx-cpxx.its

-C gzip 
-a  0x41008000 
-e  0x41008000  
-A arm 
-v 4.4.60

根据fit-qcom-ipq60xx-cpxx.its生成包含所有dtb的fit-qcom-ipq60xx-cpxx.itb文件

默认是config@cp03-c1

最终会把fit-qcom-ipq60xx-cpxx.itb拷贝到qsdk\bin\ipq\openwrt-ipq-ipq60xx-qcom-ipq60xx-cpxx-fit-uImage.itb

重复上面两步，只是在制作its的时候指定不使用gzip压缩，且内核为initramfs，即生成带ramfs的itb文件

即生成单个initramfs版本的内核和单个dtb的itb文件

例如：下面使用Image-initramfs 來制作单个的itb文件

/home/xym/works/03.qsdk_oem/qsdk/scripts/mkits.sh 
-D qcom-ipq6018-cp03-c1 
-o /home/xym/works/03.qsdk_oem/qsdk/build_dir/target-arm_cortex-a7_musl-1.1.16_eabi/linux-ipq_ipq60xx/fit-qcom-ipq6018-cp03-c1.its 
-k  /home/xym/works/03.qsdk_oem/qsdk/build_dir/target-arm_cortex-a7_musl-1.1.16_eabi/linux-ipq_ipq60xx/Image-initramfs 
-d  /home/xym/works/03.qsdk_oem/qsdk/build_dir/target-arm_cortex-a7_musl-1.1.16_eabi/linux-ipq_ipq60xx/linux-4.4.60/arch/arm/boot/dts//qcom-ipq6018-cp03-c1.dtb 
-C  none -a 0x41008000 -e 0x41008000 -A arm -v 4.4.60

生成的itb文件如下

openwrt-ipq-ipq60xx-qcom-ipq6018-cp01-c2-fit-uImage-initramfs.itb
openwrt-ipq-ipq60xx-qcom-ipq6018-cp01-c3-fit-uImage-initramfs.itb
openwrt-ipq-ipq60xx-qcom-ipq6018-cp01-c4-fit-uImage-initramfs.itb
openwrt-ipq-ipq60xx-qcom-ipq6018-cp01-c1-fit-uImage-initramfs.itb
openwrt-ipq-ipq60xx-qcom-ipq6018-cp02-c1-fit-uImage-initramfs.itb
openwrt-ipq-ipq60xx-qcom-ipq6018-cp03-c1-fit-uImage-initramfs.itb

下面这一段不知道为什么和步骤7重复

然后生成总的fit-qcom-ipq60xx-cpxx.itb

/home/xym/works/03.qsdk_oem/qsdk/scripts/mkits.sh 
-D qcom-ipq60xx-cpxx 
-o /home/xym/works/03.qsdk_oem/qsdk/build_dir/target-arm_cortex-a7_musl-1.1.16_eabi/linux-ipq_ipq60xx/fit-qcom-ipq60xx-cpxx.its

注意ubinize-ipq60xx.cfg原始文件存放目录qsdk\target\linux\ipq\image目录下，所以下面也是从该目录拷贝到qsdk/build_dir/target-arm_cortex-a7_musl-1.1.16_eabi/linux-ipq_ipq60xx下才用的，

脚本分析

执行prepareSingleImage.py脚本

./ipq/prepareSingleImage.py --arch ipq6018 --in ./ipq --gencdt --genbootconf --genpart --genmbn

功能分析

准备材料

if bootImgDir != "":
			copy_images("BOOT", bootImgDir)
		if tzImgDir != "":
			copy_images("TZ", tzImgDir)
		if nhssImgDir != "":
			copy_images("NHSS" + mode, nhssImgDir)
		if rpmImgDir != "":
			copy_images("RPM", rpmImgDir)
		if wififwImgDir != "":
			copy_images("WIFIFW", wififwImgDir)

先執行gen_cdt()

# 注意：memory默认取值为 prepareSingleImage.py 的--memcry参数  缺省情况下：默认是"default" 只能是256或者512 否则就失败
gen_cdt_bin.py -c <chipcode>/common/build/ipq/ipq6018/config.xml -o ./ipq/ -m  memory

下面分析gen_cdt_bin.py

# 解析<chipcode>/common/build/ipq/ipq6018/config.xml文件 根据 memory配置
# 重写<chipcode>/common/build/ipq/ipq6018/cdt/256M32_DDR3.xml

#然后遍历<chipcode>/common/build/ipq/ipq6018/machid_xml所有文件执行
<chipcode>/common/build/ipq/scripts/cdt_generator.py <chipcode>/common/build/ipq/ipq6018/machid_xml/AP-CP01-C1_256M32_DDR3.xml cdt-AP-CP01-C1_256M32_DDR3.bin

因为是遍历 
所以这里会生成
cdt-AP-CP01-C1_256M32_DDR3.bin
cdt-AP-CP01-C2_256M32_DDR3.bin
cdt-AP-CP01-C3_256M32_DDR3.bin
等等

上面的步骤在打包日志信息上也能看到

总结
上面生成：
cdt-AP-CP02-C1_256M32_DDR4.bin
cdt-AP-CP01-C4_256M32_DDR3.bin
cdt-DB-CP01_256M32_DDR3.bin
cdt-AP-CP01-C3_256M32_DDR3.bin
cdt-CP-EMU_256M32_DDR3.bin
cdt-AP-CP01-C1_256M32_DDR3.bin
cdt-DB-CP02_1024M32_DDR4.bin
cdt-AP-CP03-C1_256M16_DDR3.bin
cdt-AP-CP01-C2_256M32_DDR3.bin

接着执行gen_bootconfig()

gen_bootconfig_bin.py -c <chipcode>/common/build/ipq/ipq6018/config.xml -o ./ipq

下面分析gen_bootconfig_bin.py

# 解析<chipcode>/common/build/ipq/ipq6018/config.xml 根据里面的 NAND_PARAMETER 参数

<chipcode>/common/build/ipq/scripts/nand_mbn_generator.py <chipcode>/common/build/ipq/ipq6018/bootconfig/bootconfig.xml nand_raw_bootconfig.bin
也就是生成
nand_raw_bootconfig.bin 

然后执行
#rawpart_path ：<chipcode>/common/build/ipq/nand_raw_bootconfig
# nand_bootconfig ：<chipcode>/common/build/ipq/nand_raw_bootconfig.bin 
<chipcode>/common/build/ipq/bootconfig_tool -s nand_pagesize -p  nand_pages_per_block -i rawpart_path -o nand_bootconfig
最终生成 <chipcode>/common/build/ipq/nand_raw_bootconfig.bin 

打包日志也能看到输出信息

接下來執行gen_part()

gen_flash_partition_bin.py -c <chipcode>/common/build/ipq/ipq6018/config.xml -f flash_type -o./ipq

# -c 配置路徑  <chipcode>/common/build/ipq/ipq6018/config.xml

# -f 存储类型 nor、tiny-nor、nand、norplusnand、emmc、norplusemmc、tiny-nor-debug
gen_flash_partition.py -c <chipcode>/common/build/ipq/ipq6018/config.xml -o <chipcode>/common/build/ipq/norplusnand-system-partition-ipq6018.bin -f norplusnand

#生成的bin文件输出路径<chipcode>/common/build/ipq/norplusnand-system-partition-ipq6018.bin

python nand_mbn_generator.py <chipcode>/common/build/ipq/ipq6018/flash_partition/norplusnand-partition.xml <chipcode>/common/build/ipq/norplusnand-system-partition-ipq6018.bin

# -c 1
# -u <user partition file>  即<chipcode>/common/build/ipq/ipq6018/flash_partition/norplusnand-partition.xml 
# -o <output_system_partition> 即 <chipcode>/common/build/ipq/norplusnand-system-partition-ipq6018.bin

# 最终生成的就是
# <chipcode>/common/build/ipq/norplusnand-system-partition-ipq6018.bin

下面執行gen_bootldr 这里没有用到先不分析

下面执行gen_mbn()

elftombn.py -f ./ipq/openwrt-ipq6018-u-boot.elf -o ./ipq/openwtt-ipq6018-u-boot.mbn -v 6

功能就是在uboot前加一堆的头部信息 

python /home/xym/works/03.qsdk_oem/./apss_proc/out/meta-scripts/pack_hk.py

下一步
python /home/xym/works/03.qsdk_oem/.//apss_proc/out/meta-scripts/pack_hk.py 
--arch ipq6018 
--fltype nand 
--srcPath ./ipq 
--inImage ./ipq 
--outImage ./bin 
--image_type hlos   和上面不一样的地方
