imx的MFGTools配置流程分析

1、1、MFG说明MFGToo工具是freescale 专门针对i.MX处理器专门使用的烧写工具，用来将编译好的文 件系统和镜像文件烧写到板子上。2、文件结构以明远智睿 MY-I.MX6-MFG-TOOL-V2.3为例：文件结构cfg.ini 指定LIST，ucl2.xml根据此定义，找到对应的操作部分流程：Profiles/MX6Q Li nux Update/OS Firmware/ulmage打开MfgTool2.exe时，会读取uImage的内容。如果没有uImage,打开MfgTool2.exe，提示:Profiles/MX6Q Li nux Update/OS Firmware/ucl

2、2.xmlMFG的工作流程由配置文件决定，配置文件即： ucl2.xml明远，LIST name=Android-MYZR-SPI_NOR-EMMCvSTATE name=Updater dev=MSC vid=066F pid=37FF/ulmage address=v/CFG/全局变量ucl2.xml 将烧录过程分成两个阶段：BootStrap和Updater/dev、vid和pid :分别对应两个阶段的设备名、设备对应连接的USB vid和pid号/针对imx6系列，在BootStrap 阶段，有效的设备名只有 MX6QMX6D MX6SL在Updater阶段，有效的设备名只有MSCvL

22、hould be connected with the USB pid“37FF” and vid “066F” .Update Comma nd ListThe tool uses Update Comma nd List (UCL) to specify all the user tasks. The UCL contains a disti net list for each use case. Each list contains a set of comma ndelements with attributes for the command type, body, and payl

23、oad. The command element text provides a user interface message for the current operation.Each UCL begins from while ending with , the nameof which can be specified by users. Parameter “desc” is used for comment purpose.There are two types of commands: host specific commands and firmware specific co

24、mmands.Host specific commandsare parsed and executed by host tool while firmware specific commands are parsed and executed by firmware runs on targeted device.Host Specific CommandsThe example below shows a typical command.“ state ” indicates the phase of the command executed and命令执行的阶段“type ” speci

25、fies the type of a command.命令的类型“ body” is a parameter of the command.命令的参数“file ” is another parameter.命令参数“Loading Kernel ” is a description of the command. 当前命令的描述Loadi ngKernel.v/CMDComma nc BodytypeOther Descripti on paramete rsloadfileAddressloadSectionsetSecti onHasFlashHeaderCodeOffsetDownl
