1、前言
MfgTools軟件工具是NXP官方進行提供的用於I.MX系列的SoC進行系統燒寫的一個軟件，能在Windows系統上使用，通過USB OTG接口完成系統燒寫，一般在開發板進行量產的時候進行使用，能提高系統的燒寫效率，當然，肯定也能在系統調試時使用，對於該軟件的獲取，直接去NXP官方網站上即可獲取。
2、MfgTools基本原理
接下來，將對MfgTools的系統燒寫基本原理進行簡單介紹，軟件下載解壓后，目錄如下所示：
可以看到，MfgTools軟件目錄下的目錄和文件非常多，但是我們並不需要全部了解和關心，了解進行系統燒寫時需要用到和修改的就好，軟件目錄下的MfgTool2.exe就是燒寫軟件，以.vbs結尾的文件就是燒寫的配置文件，該軟件能支持多款I.MX系統的SoC系統燒寫，還能支持Nand Flash、eMMC和SD卡等存儲介質系統燒寫，因此，在對每一款SoC進行系統燒寫之前，肯定要進行配置，指定好需要燒寫的芯片以及存儲介質，.vbs結尾的文件就是配置腳本，能直接雙擊運行，例如，下面的.vbs腳本功能：
| 腳本文件 | 功能 |
| mfgtool2-yocto-mx-evk-emmc.vbs | NXP官方evk評估板的eMMC燒寫腳本 |
| mfgtool2-yocto-mx-evk-nand.vbs | NXP官方evk評估板的Nand Flash燒寫腳本 |
MfgTools燒寫的基本原理為將目標板的啟動模式設置為Serial Downloader模式（BOOT_MODE[1:0]=01），然后通過USB OTG接口將uboot、Linux kernel和dtb等下載到DRAM內存中，然后將DRAM里面的Linux系統啟動起來，接下來通過這個啟動的Linux系統將目標鏡像固化到Nand Flash、eMMC或SD卡等，所以整個固件燒寫的過程大致可以分為兩個階段進行。
接下來，看看該軟件燒寫的固件在哪里，進入到下面的目錄：
L4.1.15_2.0.0-ga_mfg-tools\mfgtools-without-rootfs\mfgtools\Profiles\Linux\OS Firmware
該目錄打開后，如下：
我們主要關注的是files和firmware這兩個文件夾，還有ucl2.xml文件，其中files和firmware目錄中保存了我們需要燒寫的固件，files文件夾中保存了需要固化到存儲介質的鏡像文件，firmware文件夾中保存了我們需要在DRAM中啟動的Linux系統鏡像，ucl2.xml文件描述了整個燒寫過程，決定了我們要向哪個SoC燒寫哪個固件，因此這些文件夾和目錄非常重要，必須要清晰地了解。
在了解這些文件之前，先來看看前面介紹到.vbs腳本文件，例如mfgtool2-yocto-mx-evk-nand.vbs，燒寫Nand Flash的配置腳本，該文件代碼如下：
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，該腳本運行了目錄下的mfgtool2.exe軟件，並且定義了一堆的變量，變量都有相應的值，對於i.mx6ul這款SoC從Nand Flash中啟動，總結一些重要的變量，如下：
"6uluboot=14x14evk" "6uldtb=14x14-evk" "nand=nand" "nanddtb=gpmi-weim" "part_uboot=0" "part_kernel=1" "part_dtb=2" "part_rootfs=3"
得到了這些變量后，接下來，我們看看ucl2.xml文件，該文件將決定燒寫什么固件，怎么燒寫，先來看看該文件的整體框架，如下所示：
可以看到，整個.xml文件是從"<UCL>"開始，然后以"</UCL>"結束，"<CFG>"到"</CFG>"之間貌似是配置相關的內容，判斷當前是在給I.MX系列的哪個SoC進行鏡像燒寫，並且具有很多個<LIST>描述的內容，"<LIST>"和"</LIST>"之間很明顯是針對不同存儲介質所要執行的燒寫命令。
接下來，展開其中的一個"<LIST>"進行講解，以燒寫Nand Flash存儲介質這個"<LIST>"為例看看相關的命令，在上面已經提及過，MfgTools軟件燒寫大致分為兩個階段，第一階段是通過USB OTG接口將uboot、Linux kernel和dtb等下載到DRAM中，並將該Linux系統進行啟動，第二階段則是通過這個啟動的Linux系統將目標鏡像固化到存儲介質中，燒寫Nand Flash的"<LIST>"代碼如下：

接下來，我們將分兩個階段對這些代碼進行分析，從代碼中可以看到，對固件的燒寫會進行設備的判斷，畢竟該軟件適用於NXP中I.MX系列的SoC燒寫，將以i.mx6ul這款SoC進行舉例分析，看看這兩個階段到底是燒寫了哪些固件。
第一階段的代碼如下：
<!--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>"命令從上到下執行，如果當前的SoC為i.mx6ul的話，也就是dev="MX6UL"，那么將會先執行下面的"<CMD>"將uboot下載到DRAM內存中：
<CMD state="BootStrap" type="boot" body="BootStrap" file ="firmware/u-boot-imx6ul%6uluboot%_%nand%.imx" ifdev="MX6UL">Loading U-boot</CMD>
可以知道下載的固件文件是在firmware目錄下，文件為：
file ="firmware/u-boot-imx6ul%6uluboot%_%nand%.imx"
在上面對.vbs文件進行分析的時候，已經對其中的變量進行總結了，如下：
"6uluboot=14x14evk"
"nand=nand"
將其替換后，也就是該"<CMD>"執行后，對於i.mx6ul這款SoC將會下載下面這個uboot文件到DRAM中：
file ="firmware/u-boot-imx6ul14x14evk_nand.imx"
接下來，將會執行下一個"<CMD>"，將會將kernel下載到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下載到DRAM的0x80800000內存地址中，要下載的kernel固件如下：
file="firmware/zImage"
繼續執行下一個"<CMD>"，將會將initramfs下載到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被下載到DRAM的0x83800000內存地址中，下載的固件為：
file="firmware/%initramfs%"
繼續執行下一個"<CMD>"，將dtb固件下載到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將被下載到DRAM的0x83000000內存地址中，下載的固件為：
file="firmware/zImage-imx6ul-%6uldtb%-%nanddtb%.dtb"
將其中的變量替換后，下載的dtb固件如下：
file="firmware/zImage-imx6ul-14x14evk-gpmi-weim.dtb"
在第一階段的最后，則是Jumping to OS image，應該就是去啟動這個已經下載到DRAM的Linux系統，從而進入到系統燒寫的第二個階段，在看第二階段的代碼前，先總結一下第一階段燒寫了哪些固件，基於i.mx6ul這款SoC，下載到DRAM的固件如下：
| 固件 | 下載文件 |
| uboot | firmware/u-boot-imx6ul14x14evk_nand.imx |
| kernel | firmware/zImage |
| initramfs | firmware/%initramfs% |
| dtb | firmware/zImage-imx6ul-14x14evk-gpmi-weim.dtb |
接下來，繼續分析第二階段的代碼，該階段則是通過啟動的Linux系統將需要燒寫的鏡像固化到目標板存儲介質中，首先是燒寫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% $FILE">Flashing Bootloader</CMD>
在燒寫uboot之前，需要執行下面的"<CMD>"將Nand Flash中存儲uboot的區域進行擦除：
<CMD state="Updater" type="push" body="$ flash_erase /dev/mtd%part_uboot% 0 0">Erasing Boot partition</CMD>
將其中的變量進行替換后，也就是會執行下面的命令進行擦除Nand Flash中uboot的區域：
flash_erase /dev/mtd0 0 0
對於i.mx6ul這款SoC，接下來會執行下面的"<CMD>"，通過USB OTG接口發送要固化的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>
同樣道理，將其中的變量替換后，也就得到了要固化的uboot的文件，如下：
file ="files/u-boot-imx6ul14x14evk_nand.imx"
接下來，就是執行下面這個"<CMD>"進行uboot固件燒寫：
<CMD state="Updater" type="push" body="$ kobs-ng init -x -v --chip_0_device_path=/dev/mtd%part_uboot% $FILE">Flashing Bootloader</CMD>
對該語句還不是很懂，先跳過該分析。
繼續往下分析，就是燒寫kernel到Nand Flash的"<CMD>"，代碼如下：
<!--burn the kernel to NAND: --> <CMD state="Updater" type="push" body="$ 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>
同樣是先擦除Nand Flash中存儲kernel鏡像的區域，執行的是下面的命令進行擦除：
flash_erase /dev/mtd1 0 0
接下來，通過USB OTG接口將kernel zImage發送，並使用下面的命令，將kernel固化到目標板的Nand Flash中：
nandwrite -p /dev/mtd1 -p $FILE
燒寫的kernel固件為：
file="files/zImage"
接下來，繼續分析，則是燒寫dtb到Nand Flash的"<CMD>"，代碼如下所示：
<!--burn the dtb to NAND: --> <CMD state="Updater" type="push" body="$ 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 $FILE">Flashing dtb</CMD>
同樣是先使用flash_erase命令擦除Nand Flash中存儲dtb區域，使用的是下面的命令：
flash_erase /dev/mtd2 0 0
對於i.mx6ul這款SoC的話，要燒寫的dtb固件為：
file="files/zImage-imx6ul-%6uldtb%-%nanddtb%.dtb"
將其中的變量進行替換后，也就是下面的文件：
file="files/zImage-imx6ul-14x14-evk-gpmi-weim.dtb"
最后，則是燒寫rootfs到Nand Flash的"<CMD>"，其代碼如下：
<!--burn the rootfs to NAND:--> <CMD state="Updater" type="push" body="$ 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>
同樣也是要先使用flash_erase命令，將Nand Flash中存儲rootfs的區域進行擦除，先執行下面的命令：
flash_erase /dev/mtd3 0 0
接下來就是進行rootfs的燒寫，根文件系統的格式為ubifs，對於i.mx6ul這款SoC是沒有GPU的，因此燒寫的是下面的rootfs：
file="files/rootfs_nogpu.tar.bz2"
到這里，對第二階段的系統燒寫過程就介紹完了，接下來，基於i.mx6ul這款SoC，總結一下在第二階段燒寫了哪些文件：
| 固件 | 文件 |
| uboot | files/u-boot-imx6ul14x14evk_nand.imx |
| kernel | files/zImage |
| dtb | files/zImage-imx6ul-14x14-evk-gpmi-weim.dtb |
| rootfs | files/rootfs_nogpu.tar.bz2 |
這就是整個MfgTools軟件工具的大致燒寫原理，所以當你打開files和firmware文件夾的時候，會發現里面保存了大量的uboot和kernel等固件，都是針對於NXP官方基於I.MX系統的SoC的評估板而定制的，弄懂了大致的燒寫原理和燒寫的文件后，接下來就可以進行MfgTools軟件的定制了，編譯好相關的固件后，修改相應的代碼，從而適配自己定制的目標板。
3、MfgTools更新固件
在對MfgTools軟件的基本燒寫原理有大致的了解后，接下來，我們去使用這款軟件去更新我們目標板的固件，筆者使用的是盈鵬飛公司研發生產的核心板CoM-P6UL（SoC：I.MX6UL，RAM：256MB，Nand Flash：256MB），如下：
先編譯和構建好我們需要燒寫的uboot、kernel、dtb和rootfs相關固件，如下所示：
接下來，將要燒寫的固件文件名依次改成，上面分析MfgTools基本原理總結出來的文件名稱，並將files和firmware的文件進行替換，當然，你也可以修改.vbs腳本配置文件和.xml文件，只要燒寫的文件名稱對應即可，修改后文件名后，如下：
對應的文件名修改完成后，依次將對應的文件替換到files和firmware目錄即可，這時候，我們需要燒寫到Nand Flash的固件就准備好了。
接下來，將目標板的啟動方式設置為啟動模式設置為Serial Downloader模式（BOOT_MODE[1:0]=01），然后通過USB OTG接口將目標板和PC進行連接，待驅動安裝完成后，進入MfgTools軟件目錄，雙擊打開需要燒寫的.vbs配置腳本文件，如下腳本：
mfgtool2-yocto-mx-evk-nand.vbs
打開軟件后，如下所示，表示PC端和目標板已經成功連接，可以進行燒寫了：
在點擊Start按鈕燒寫之前，可以通過usb to serial將調試的串口進行打開，能看到整個燒寫過程打印的log，接下來點擊Start開始燒寫，如果固件沒有問題的話，燒寫成功如下：
接下來，點擊Stop按鈕停止固件燒寫，並點擊Exit按鈕退出MfgTools軟件即可。
最后，將目標板的啟動方式設置為啟動模式設置為Internal Boot模式（BOOT_MODE[1:0]=10），將調試串口打開，並重新對目標板上電，啟動更新好的固件系統。
使用軟件更新固件時，串口打印的log如下：
