imx6 MFG TOOL 分析

之前分析过mfgtool的内容，最近从官网下载，返现新版的mfgtool工具将imx6各种版本的linux/android都使用一个工具进行烧录。所以从新分析一下。

新版与旧版的一个区别是烧写使用的uboot后缀是.imx，而不是原来的.bin。以后缀.imx结尾的uboot在镜像开头1k的地方添加了IVT表。

本文分析的MFG_TOOL版本是：IMX6_L5.1_2.1.0_MFG_TOOL。

vbscript

---

首先双击对应的vbscript启动mfgtool工具。一般从vbs的名称就能够看出是烧录何种cpu以及存储设备的类型。例如：

mfgtool2-android-mx6q-sabresd-emmc.vbs

表示烧录的镜像运行的系统是android, cpu是mx6q, 存储设备类型为emmc.

详细分析如下：

Set wshShell = CreateObject("WScript.shell")
wshShell.run "mfgtool2.exe -c ""linux"" -l ""eMMC-Android"" -s ""board=sabresd""  -s ""folder=sabresd"" -s ""soc=6q"" -s ""mmc=3"" -s ""data_type="""
Set wshShell = Nothing

参数的含义：
-c: 芯片配置文件夹名称 linux
-l: list名称，对应ucl2.xml文件中的LIST标签的name，后面会说明。
-s: 变量名称, cfg.ini以及ucl2.xml中会用到。

cfg.ini

---

脚本运行, mfgtool工具启动，解读cfg.ini文件，上面的vbs脚本中的参数会覆盖cfg.ini文件中的参数。

[profiles]
chip = Linux

[platform]
board = SabreSD

# vbs中 -l ""eMMC-Android"" 已经制定为eMMC-Android，所以下面的LIST无效。
[LIST]
name = SDCard

[variable]
board = sabresd
mmc = 0
sxuboot=17x17arm2
sxdtb=17x17-arm2
7duboot=sabresd
7ddtb=sdb
6uluboot=14x14ddr3arm2
6uldtb=14x14-ddr3-arm2
ldo=
plus=
initramfs=fsl-image-mfgtool-initramfs-imx_mfgtools.cpio.gz.u-boot
seek = 1
sxnor=qspi2
7dnor=qspi1
6ulnor=qspi1
nor_part=0

ucl2.xml

---

根据 vbs和cfg.ini文件中的参数指定的LIST名称，选择正确的操作进行进行烧录。

这个目录里面有很多文件,烧录的时候要用到的uboot,内核，文件系统到RAM中，运行

• 首先烧录Profiles/Linux/OS Firmware/firmware文件夹的镜像到RAM中运行系统。

• 系统运行之后烧录Profiles/Linux/OS Firmware/files/android/sabresd/中的镜像到emmc中

<!-- 首先判断不同芯片USB的vid和pid-->
