imx6的MFGTools配置、流程、分析

1 MFG 说明说明 MFGTool 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 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 MFG 先把 OS Firmware 下面的 uboot bin uImage initramfs cpio gz uboot 下载到 RAM 中 运行 再执行具体的 烧录过程 Profiles MX6Q Linux Update OS Firmware uImage 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 Linux

configure the users operation 可以灵活的自定义操作 An xml file typically consists of a number of tasks which can be executed by running the manufacturing tool just once 大量任务 开始运行工具时 执行 UTP mode operation Global Configuration 全局配置全局配置 Mfg tool uses global configuration to recognize which device the user wants to flash among different USB devices connected to the PC 选择设备 与 PC 相连的 USB Let s explain it by an example 下面为例 说明 Global configuration is contained between parameter and 定义的全局配置参数 indicates the first phase of the burning process the phase name is BootStrap and a device named MX6Q should be connected with the USB pid 0054 and vid 15A2 For i MX 6 serial in the phase BootStrap the valid strings for dev are MX6Q MX6D MX6SL in the phase Updater the valid string for dev is MSC 烧录过程的第一步 BootStrap indicates the second phase of the burning process the phase name is Updater and a device named MSC should be connected with the USB pid 37FF and vid 066F Update Command List The tool uses Update Command List UCL to specify all the user tasks The UCL contains a distinct list for each use case Each list contains a set of command elements with attributes for the command type body and payload The command element text provides a user interface message for the current operation Each UCL begins from while ending with the name of 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 commands Host specific commands are parsed and executed by host tool while firmware specific commands are parsed and executed by firmware runs on targeted device Host Specific Commands The example below shows a typical command state indicates the phase of the command executed and 命令执行的阶段 type specifies 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 Loading Kernel Comman d type BodyOther parameters Description loadfile Address loadSectio n setSection HasFlashHe ader CodeOffset Download an image to RAM It is strongly recommended to follow the example provided in release package since it involves ROM code parameters which may not be easy to understand file specify the path and name of the image file 说明文件的路径 名称 Parameter address specifies the RAM address where the image is located 文件在 RAM 的地址 loadSection a parameter used by ROM code should be set to OTH ROM 代码所用的参数 setSection a parameter used by ROM code should be set to OTH if there are other images to be loaded set to APP if the last image is loaded 还有其他文件 OTH 最后一个文件 APP HasFlashHeader set TRUE if the image contains a flash header or set to FALSE 包含 flash header 设成 TRUE 否则 设成 FALSE CodeOffset the address offset of first executed instruct within the image 文件中执行的第一条指令的偏移地址 The command is only for Bulk IO mode i MX device except i MX50 HID mode device jumpNotify ROM code to jump to the RAM image to run The command must be followed after a load command in which setSection value is set to APP The command is only for Bulk IO mode i MX device except i MX50 HID mode device bootRecoveryFile if Download an image to RAM Firmware Specific Commands If a command is typed as push which means the command is parsed and executed by the targeted device instead of host push 是目标机执行的命令 the only thing host has to do is to send the command to the targeted device 主机只是将命令发给目标机 The commands actually executed by OS image are downloaded in Command lists As a result each OS has its own commands Command Arguments Description None Request to send the device identity information in XML form integer Initiate the reboot depending on argument 3 means reboot while other values will force a shutdown string Execute shell command Example echo hello from utp flush None Wait for all data transfer to be finished and processed ffs None Partition the SD card and flash the boot stream to it mknod device class device item node t o create type Create the device node by parsing sysfs entry 创建设备节点 Example mknod class mtd mtd0 dev mtd0 read string Read the file specified by parameter and send it to the host If there is no such file the appropriate status will be returned send None Receive the file from the host Subsequent shell commands can refer to the file received as FILE Example selftest None Perform self diagnostic returns either pass or appropriate status Implemented as empty function in current release save string Save the file received by command send to the file specified as parameter pipe string require file attribute Execute shell command and read data from stdio pipe IN mfg will send file to stdio pipe OUT It is useful for big data transfer more than physical memory size Finish Flashing NAND Note The above two commands must be combined to use Recommend Please add below command prior to pipe command to free some memory proc sys vm drop caches release memory wff NONE Deprecate Prepare Write firmware to flash wfs NONE Deprecate Prepare Write firmware to SD CARD ffs NONE Write firmware to SD wrf NONE require file attribute ubiformat nand with ubi image Example Finish Flashing
