This is abstracted from the ucl2.xml( Mfgtools-Rel-13.01.00_ER_MX6Q_UPDATER).

I have some questions about it:




    <STATE name="BootStrap" dev="MX6Q" vid="15A2" pid="0054"/>

  <STATE name="Updater"   dev="MSC" vid="066F" pid="37FF"/>



<LIST name="ubuntu-SabreSD-eMMC" desc="Choose eMMC android as media">



/*this is the first stage-"BootStrap", the pc communicate with bootrom through usb( vid="15A2" pid="0054"), pc send the uboot-"u-boot-mx6q-sabresd.bin",kernel--"uImage",rootfs--"initramfs.cpio.gz.uboot" to the bootroom.

bootroom put these files at ram.

then bootroom jump into the uboot at the ram,then uboot jump the the kernel,then a little rootfs is booted


I want know all the CMDs with the state="BootStrap" will be handled by bootrom?


    <CMD state="BootStrap" type="boot" body="BootStrap" file ="u-boot-mx6q-sabresd.bin" >Loading U-boot</CMD>


        loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" >Loading Initramfs.</CMD>

    <CMD state="BootStrap" type="jump" > Jumping to OS image. </CMD>




this is the second stage-"Updater", now the little roofs control the imx6, it is a little linux os. and There is a app in the  little linux os,which open a usb device(  vid="066F" pid="37FF") and

communicate with pc through this  usb device(  vid="066F" pid="37FF").

all the CMDs below, with the state="Updater", will be handled by the little linux os on imx6?


How the  uboot-"u-boot-mx6q-sabresd.bin",kernel--"uImage",rootfs--"initramfs.cpio.gz.uboot" are built?

How can I custom these files?where is source code for the  "initramfs.cpio.gz.uboot"?

There should be a app will handle the CMDs from pc, where is the source code?


  <CMD state="Updater" type="push" body="$ ls /dev/*"/>
