1、前言
MfgTools软件工具是NXP官方进行提供的用于I.MX系列的SoC进行系统烧写的一个软件，能在Windows系统上使用，通过USB OTG接口完成系统烧写，一般在开发板进行量产的时候进行使用，能提高系统的烧写效率，当然，肯定也能在系统调试时使用，对于该软件的获取，直接去NXP官方网站上即可获取。
2、MfgTools基本原理
接下来，将对MfgTools的系统烧写基本原理进行简单介绍，软件下载解压后，目录如下所示：
可以看到，MfgTools软件目录下的目录和文件非常多，但是我们并不需要全部了解和关心，了解进行系统烧写时需要用到和修改的就好，软件目录下的MfgTool2.exe就是烧写软件，以.vbs结尾的文件就是烧写的配置文件，该软件能支持多款I.MX系统的SoC系统烧写，还能支持Nand Flash、eMMC和SD卡等存储介质系统烧写，因此，在对每一款SoC进行系统烧写之前，肯定要进行配置，指定好需要烧写的芯片以及存储介质，.vbs结尾的文件就是配置脚本，能直接双击运行，例如，下面的.vbs脚本功能：
| 脚本文件 | 功能 |
| mfgtool2-yocto-mx-evk-emmc.vbs | NXP官方evk评估板的eMMC烧写脚本 |
| mfgtool2-yocto-mx-evk-nand.vbs | NXP官方evk评估板的Nand Flash烧写脚本 |
MfgTools烧写的基本原理为将目标板的启动模式设置为Serial Downloader模式（BOOT_MODE[1:0]=01），然后通过USB OTG接口将uboot、Linux kernel和dtb等下载到DRAM内存中，然后将DRAM里面的Linux系统启动起来，接下来通过这个启动的Linux系统将目标镜像固化到Nand Flash、eMMC或SD卡等，所以整个固件烧写的过程大致可以分为两个阶段进行。
接下来，看看该软件烧写的固件在哪里，进入到下面的目录：
L4.1.15_2.0.0-ga_mfg-toolsmfgtools-without-rootfsmfgtoolsProfilesLinuxOS Firmware
该目录打开后，如下：
我们主要关注的是files和firmware这两个文件夹，还有ucl2.xml文件，其中files和firmware目录中保存了我们需要烧写的固件，files文件夹中保存了需要固化到存储介质的镜像文件，firmware文件夹中保存了我们需要在DRAM中启动的Linux系统镜像，ucl2.xml文件描述了整个烧写过程，决定了我们要向哪个SoC烧写哪个固件，因此这些文件夹和目录非常重要，必须要清晰地了解。
在了解这些文件之前，先来看看前面介绍到.vbs脚本文件，例如mfgtool2-yocto-mx-evk-nand.vbs，烧写Nand Flash的配置脚本，该文件代码如下：
Set wshShell = CreateObject("WScript.shell") wshShell.run "mfgtool2.exe -c ""linux"" -l ""NAND Flash"" -s
""sxuboot=sabreauto"" -s ""sxdtb=sabreauto"" -s
""6uluboot=14x14evk"" -s ""6uldtb=14x14-evk"" -s
""board=sabreauto"" -s ""nand=nand"" -s ""nanddtb=gpmi-weim"" -s
""part_uboot=0"" -s ""part_kernel=1"" -s ""part_dtb=2"" -s ""part_rootfs=3"" " Set wshShell = Nothing
可以看到，该脚本运行了目录下的mfgtool2.exe软件，并且定义了一堆的变量，变量都有相应的值，对于i.mx6ul这款SoC从Nand Flash中启动，总结一些重要的变量，如下：
"6uluboot=14x14evk" "6uldtb=14x14-evk" "nand=nand" "nanddtb=gpmi-weim" "part_uboot=0" "part_kernel=1" "part_dtb=2" "part_rootfs=3"
得到了这些变量后，接下来，我们看看ucl2.xml文件，该文件将决定烧写什么固件，怎么烧写，先来看看该文件的整体框架，如下所示：
可以看到，整个.xml文件是从"<UCL>"开始，然后以"</UCL>"结束，"<CFG>"到"</CFG>"之间貌似是配置相关的内容，判断当前是在给I.MX系列的哪个SoC进行镜像烧写，并且具有很多个<LIST>描述的内容，"<LIST>"和"</LIST>"之间很明显是针对不同存储介质所要执行的烧写命令。
接下来，展开其中的一个"<LIST>"进行讲解，以烧写Nand Flash存储介质这个"<LIST>"为例看看相关的命令，在上面已经提及过，MfgTools软件烧写大致分为两个阶段，第一阶段是通过USB OTG接口将uboot、Linux kernel和dtb等下载到DRAM中，并将该Linux系统进行启动，第二阶段则是通过这个启动的Linux系统将目标镜像固化到存储介质中，烧写Nand Flash的"<LIST>"代码如下：

接下来，我们将分两个阶段对这些代码进行分析，从代码中可以看到，对固件的烧写会进行设备的判断，毕竟该软件适用于NXP中I.MX系列的SoC烧写，将以i.mx6ul这款SoC进行举例分析，看看这两个阶段到底是烧写了哪些固件。
第一阶段的代码如下：
<!--load the uboot to DRAM: --> <CMD state="BootStrap" type="boot" body="BootStrap" file ="firmware/u-boot-imx6q%plus%%board%_%nand%.imx" ifdev="MX6Q">Loading U-boot</CMD> <CMD state="BootStrap" type="boot" body="BootStrap" file ="firmware/u-boot-imx6dl%board%_%nand%.imx" ifdev="MX6D">Loading U-boot</CMD> <CMD state="BootStrap" type="boot" body="BootStrap" file ="firmware/u-boot-imx6sx%sxuboot%_%nand%.imx" ifdev="MX6SX">Loading U-boot</CMD> <CMD state="BootStrap" type="boot" body="BootStrap" file ="firmware/u-boot-imx7d%7duboot%_%nand%.imx" ifdev="MX7D">Loading U-boot</CMD> <CMD state="BootStrap" type="boot" body="BootStrap" file ="firmware/u-boot-imx6ul%6uluboot%_%nand%.imx" ifdev="MX6UL">Loading U-boot</CMD> <CMD state="BootStrap" type="boot" body="BootStrap" file ="firmware/u-boot-imx6ul%lite%%6uluboot%_%nand%.imx" ifdev="MX6ULL">Loading U-boot</CMD> <!--load the kernel to DRAM: --> <CMD state="BootStrap" type="load" file="firmware/zImage" address="0x12000000" loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" ifdev="MX6Q MX6D">Loading Kernel.</CMD> <CMD state="BootStrap" type="load" file="firmware/zImage" address="0x80800000" loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" ifdev="MX6SL MX6SX MX7D MX6UL MX6ULL">Loading Kernel.</CMD> <!--load the initramfs to DRAM: --> <CMD state="BootStrap" type="load" file="firmware/%initramfs%" address="0x12C00000" loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" ifdev="MX6Q MX6D">Loading Initramfs.</CMD> <CMD state="BootStrap" type="load" file="firmware/%initramfs%" address="0x83800000" loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" ifdev="MX6SL MX6SX MX7D MX6UL MX6ULL">Loading Initramfs.</CMD> <!--load the dtb to DRAM: --> <CMD state="BootStrap" type="load" file="firmware/zImage-imx6q%plus%-%board%-%nanddtb%.dtb" address="0x18000000" loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" ifdev="MX6Q">Loading device tree.</CMD> <CMD state="BootStrap" type="load" file="firmware/zImage-imx6dl-%board%-%nanddtb%.dtb" address="0x18000000" loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" ifdev="MX6D">Loading device tree.</CMD> <CMD state="BootStrap" type="load" file="firmware/zImage-imx6sx-%sxdtb%-%nanddtb%.dtb" address="0x83000000" loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" ifdev="MX6SX">Loading device tree.</CMD> <CMD state="BootStrap" type="load" file="firmware/zImage-imx7d-%7ddtb%-%nanddtb%.dtb" address="0x83000000" loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" ifdev="MX7D">Loading device tree.</CMD> <CMD state="BootStrap" type="load" file="firmware/zImage-imx6ul-%6uldtb%-%nanddtb%.dtb" address="0x83000000" loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" ifdev="MX6UL">Loading device tree.</CMD> <CMD state="BootStrap" type="load" file="firmware/zImage-imx6ul%lite%-%6uldtb%-%nanddtb%.dtb" address="0x83000000" loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" ifdev="MX6ULL">Loading device tree.</CMD> <CMD state="BootStrap" type="jump" > Jumping to OS image. </CMD>
"<CMD>"命令从上到下执行，如果当前的SoC为i.mx6ul的话，也就是dev="MX6UL"，那么将会先执行下面的"<CMD>"将uboot下载到DRAM内存中：
<CMD state="BootStrap" type="boot" body="BootStrap" file ="firmware/u-boot-imx6ul%6uluboot%_%nand%.imx" ifdev="MX6UL">Loading U-boot</CMD>
可以知道下载的固件文件是在firmware目录下，文件为：
file ="firmware/u-boot-imx6ul%6uluboot%_%nand%.imx"
在上面对.vbs文件进行分析的时候，已经对其中的变量进行总结了，如下：
"6uluboot=14x14evk"
"nand=nand"
将其替换后，也就是该"<CMD>"执行后，对于i.mx6ul这款SoC将会下载下面这个uboot文件到DRAM中：
file ="firmware/u-boot-imx6ul14x14evk_nand.imx"
接下来，将会执行下一个"<CMD>"，将会将kernel下载到DRAM中，如下：
<CMD state="BootStrap" type="load" file="firmware/zImage" address="0x80800000" loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" ifdev="MX6SL MX6SX MX7D MX6UL MX6ULL">Loading Kernel.</CMD>
可以看到，kernel下载到DRAM的0x80800000内存地址中，要下载的kernel固件如下：
file="firmware/zImage"
继续执行下一个"<CMD>"，将会将initramfs下载到DRAM中，如下：
<CMD state="BootStrap" type="load" file="firmware/%initramfs%" address="0x83800000" loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" ifdev="MX6SL MX6SX MX7D MX6UL MX6ULL">Loading Initramfs.</CMD>
可以看到，initramfs被下载到DRAM的0x83800000内存地址中，下载的固件为：
file="firmware/%initramfs%"
继续执行下一个"<CMD>"，将dtb固件下载到DRAM中，如下：
<CMD state="BootStrap" type="load" file="firmware/zImage-imx6ul-%6uldtb%-%nanddtb%.dtb" address="0x83000000" loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" ifdev="MX6UL">Loading device tree.</CMD>
可以看到，dtb将被下载到DRAM的0x83000000内存地址中，下载的固件为：
file="firmware/zImage-imx6ul-%6uldtb%-%nanddtb%.dtb"
将其中的变量替换后，下载的dtb固件如下：
file="firmware/zImage-imx6ul-14x14evk-gpmi-weim.dtb"
在第一阶段的最后，则是Jumping to OS image，应该就是去启动这个已经下载到DRAM的Linux系统，从而进入到系统烧写的第二个阶段，在看第二阶段的代码前，先总结一下第一阶段烧写了哪些固件，基于i.mx6ul这款SoC，下载到DRAM的固件如下：
| 固件 | 下载文件 |
| uboot | firmware/u-boot-imx6ul14x14evk_nand.imx |
| kernel | firmware/zImage |
| initramfs | firmware/%initramfs% |
| dtb | firmware/zImage-imx6ul-14x14evk-gpmi-weim.dtb |
接下来，继续分析第二阶段的代码，该阶段则是通过启动的Linux系统将需要烧写的镜像固化到目标板存储介质中，首先是烧写uboot到Nand Flash的"<CMD>"，如下：
<!--burn the uboot to NAND: --> <CMD state="Updater" type="push" body="$ mount -t debugfs debugfs /sys/kernel/debug">Mounting debugfs</CMD> <CMD state="Updater" type="push" body="$ flash_erase /dev/mtd%part_uboot% 0 0">Erasing Boot partition</CMD> <CMD state="Updater" type="push" body="send" file="files/u-boot-imx6q%plus%%board%_%nand%.imx" ifdev="MX6Q">Sending U-Boot</CMD> <CMD state="Updater" type="push" body="send" file="files/u-boot-imx6dl%board%_%nand%.imx" ifdev="MX6D">Sending U-Boot</CMD> <CMD state="Updater" type="push" body="send" file="files/u-boot-imx6sx%sxuboot%_%nand%.imx" ifdev="MX6SX">Sending U-Boot</CMD> <CMD state="Updater" type="push" body="send" file="files/u-boot-imx7d%7duboot%_%nand%.imx" ifdev="MX7D">Sending U-Boot</CMD> <CMD state="Updater" type="push" body="send" file="files/u-boot-imx6ul%6uluboot%_%nand%.imx" ifdev="MX6UL">Sending u-boot.bin</CMD> <CMD state="Updater" type="push" body="send" file="files/u-boot-imx6ul%lite%%6uluboot%_%nand%.imx" ifdev="MX6ULL">Sending u-boot.bin</CMD> <CMD state="Updater" type="push" body="$ kobs-ng init -x -v --chip_0_device_path=/dev/mtd%part_uboot% $FILE">Flashing Bootloader</CMD>
在烧写uboot之前，需要执行下面的"<CMD>"将Nand Flash中存储uboot的区域进行擦除：
<CMD state="Updater" type="push" body="$ flash_erase /dev/mtd%part_uboot% 0 0">Erasing Boot partition</CMD>
将其中的变量进行替换后，也就是会执行下面的命令进行擦除Nand Flash中uboot的区域：
flash_erase /dev/mtd0 0 0
对于i.mx6ul这款SoC，接下来会执行下面的"<CMD>"，通过USB OTG接口发送要固化的uboot固件：
<CMD state="Updater" type="push" body="send" file="files/u-boot-imx6ul%6uluboot%_%nand%.imx" ifdev="MX6UL">Sending u-boot.bin</CMD>
同样道理，将其中的变量替换后，也就得到了要固化的uboot的文件，如下：
file ="files/u-boot-imx6ul14x14evk_nand.imx"
接下来，就是执行下面这个"<CMD>"进行uboot固件烧写：
<CMD state="Updater" type="push" body="$ kobs-ng init -x -v --chip_0_device_path=/dev/mtd%part_uboot% $FILE">Flashing Bootloader</CMD>
对该语句还不是很懂，先跳过该分析。
继续往下分析，就是烧写kernel到Nand Flash的"<CMD>"，代码如下：
<!--burn the kernel to NAND: --> <CMD state="Updater" type="push" body="$ flash_erase /dev/mtd%part_kernel% 0 0">Erasing Kernel partition</CMD> <CMD state="Updater" type="push" body="send" file="files/zImage">Sending kernel zImage</CMD> <CMD state="Updater" type="push" body="$ nandwrite -p /dev/mtd%part_kernel% -p $FILE">Flashing Kernel</CMD>
同样是先擦除Nand Flash中存储kernel镜像的区域，执行的是下面的命令进行擦除：
flash_erase /dev/mtd1 0 0
接下来，通过USB OTG接口将kernel zImage发送，并使用下面的命令，将kernel固化到目标板的Nand Flash中：
nandwrite -p /dev/mtd1 -p $FILE
烧写的kernel固件为：
file="files/zImage"
接下来，继续分析，则是烧写dtb到Nand Flash的"<CMD>"，代码如下所示：
<!--burn the dtb to NAND: --> <CMD state="Updater" type="push" body="$ flash_erase /dev/mtd%part_dtb% 0 0">Erasing dtb partition</CMD> <CMD state="Updater" type="push" body="send" file="files/zImage-imx6q%plus%-%board%-%nanddtb%.dtb" ifdev="MX6Q">Sending Device Tree file</CMD> <CMD state="Updater" type="push" body="send" file="files/zImage-imx6dl-%board%-%nanddtb%.dtb" ifdev="MX6D">Sending Device Tree file</CMD> <CMD state="Updater" type="push" body="send" file="files/zImage-imx6sx-%sxdtb%-%nanddtb%.dtb" ifdev="MX6SX">Sending Device Tree file</CMD> <CMD state="Updater" type="push" body="send" file="files/zImage-imx7d-%7ddtb%-%nanddtb%.dtb" ifdev="MX7D">Sending Device Tree file</CMD> <CMD state="Updater" type="push" body="send" file="files/zImage-imx6ul-%6uldtb%-%nanddtb%.dtb" ifdev="MX6UL">Sending Device Tree file</CMD> <CMD state="Updater" type="push" body="send" file="files/zImage-imx6ul%lite%-%6uldtb%-%nanddtb%.dtb" ifdev="MX6ULL">Sending Device Tree file</CMD> <CMD state="Updater" type="push" body="$ nandwrite -p /dev/mtd%part_dtb% -p $FILE">Flashing dtb</CMD>
同样是先使用flash_erase命令擦除Nand Flash中存储dtb区域，使用的是下面的命令：
flash_erase /dev/mtd2 0 0
对于i.mx6ul这款SoC的话，要烧写的dtb固件为：
file="files/zImage-imx6ul-%6uldtb%-%nanddtb%.dtb"
将其中的变量进行替换后，也就是下面的文件：
file="files/zImage-imx6ul-14x14-evk-gpmi-weim.dtb"
最后，则是烧写rootfs到Nand Flash的"<CMD>"，其代码如下：
<!--burn the rootfs to NAND:--> <CMD state="Updater" type="push" body="$ flash_erase /dev/mtd%part_rootfs% 0 0">Erasing rootfs partition</CMD> <CMD state="Updater" type="push" body="$ ubiformat /dev/mtd%part_rootfs%"/> <CMD state="Updater" type="push" body="$ ubiattach /dev/ubi_ctrl -m %part_rootfs%">Attaching UBI partition</CMD> <CMD state="Updater" type="push" body="$ ubimkvol /dev/ubi0 -Nrootfs -m"/> <CMD state="Updater" type="push" body="$ mkdir -p /mnt/mtd%part_rootfs%"/> <CMD state="Updater" type="push" body="$ mount -t ubifs ubi0:rootfs /mnt/mtd%part_rootfs%"/> <CMD state="Updater" type="push" body="pipe tar -jxv -C /mnt/mtd%part_rootfs%" file="files/rootfs.tar.bz2" ifdev="MX6SL MX6D MX6Q MX6SX">Sending and writting rootfs</CMD> <CMD state="Updater" type="push" body="pipe tar -jxv -C /mnt/mtd%part_rootfs%" file="files/rootfs_nogpu.tar.bz2" ifdev="MX6UL MX7D MX6ULL">Sending and writting rootfs</CMD> <CMD state="Updater" type="push" body="frf">Finishing rootfs write</CMD> <CMD state="Updater" type="push" body="$ umount /mnt/mtd%part_rootfs%">Unmounting rootfs partition</CMD>
同样也是要先使用flash_erase命令，将Nand Flash中存储rootfs的区域进行擦除，先执行下面的命令：
flash_erase /dev/mtd3 0 0
接下来就是进行rootfs的烧写，根文件系统的格式为ubifs，对于i.mx6ul这款SoC是没有GPU的，因此烧写的是下面的rootfs：
file="files/rootfs_nogpu.tar.bz2"
到这里，对第二阶段的系统烧写过程就介绍完了，接下来，基于i.mx6ul这款SoC，总结一下在第二阶段烧写了哪些文件：
| 固件 | 文件 |
| uboot | files/u-boot-imx6ul14x14evk_nand.imx |
| kernel | files/zImage |

这就是整个MfgTools软件工具的大致烧写原理，所以当你打开files和firmware文件夹的时候，会发现里面保存了大量的uboot和kernel等固件，都是针对于NXP官方基于I.MX系统的SoC的评估板而定制的，弄懂了大致的烧写原理和烧写的文件后，接下来就可以进行MfgTools软件的定制了，编译好相关的固件后，修改相应的代码，从而适配自己定制的目标板。
3、MfgTools更新固件
在对MfgTools软件的基本烧写原理有大致的了解后，接下来，我们去使用这款软件去更新我们目标板的固件，笔者使用的是盈鹏飞公司研发生产的核心板CoM-P6UL（SoC：I.MX6UL，RAM：256MB，Nand Flash：256MB），如下：
先编译和构建好我们需要烧写的uboot、kernel、dtb和rootfs相关固件，如下所示：
接下来，将要烧写的固件文件名依次改成，上面分析MfgTools基本原理总结出来的文件名称，并将files和firmware的文件进行替换，当然，你也可以修改.vbs脚本配置文件和.xml文件，只要烧写的文件名称对应即可，修改后文件名后，如下：
对应的文件名修改完成后，依次将对应的文件替换到files和firmware目录即可，这时候，我们需要烧写到Nand Flash的固件就准备好了。
接下来，将目标板的启动方式设置为启动模式设置为Serial Downloader模式（BOOT_MODE[1:0]=01），然后通过USB OTG接口将目标板和PC进行连接，待驱动安装完成后，进入MfgTools软件目录，双击打开需要烧写的.vbs配置脚本文件，如下脚本：
mfgtool2-yocto-mx-evk-nand.vbs
打开软件后，如下所示，表示PC端和目标板已经成功连接，可以进行烧写了：
在点击Start按钮烧写之前，可以通过usb to serial将调试的串口进行打开，能看到整个烧写过程打印的log，接下来点击Start开始烧写，如果固件没有问题的话，烧写成功如下：
接下来，点击Stop按钮停止固件烧写，并点击Exit按钮退出MfgTools软件即可。
最后，将目标板的启动方式设置为启动模式设置为Internal Boot模式（BOOT_MODE[1:0]=10），将调试串口打开，并重新对目标板上电，启动更新好的固件系统。
使用软件更新固件时，串口打印的log如下：
