I have some questions about MFG tool,please help me.



In the stage of state="BootStrap", where are u-boot and uImage loaded to?

(Is it IRAM or DDR?)



After the jump command of MFG tool being excuted,what will i.MX6 do?

(is it some action about ROM?)




<LIST name="MX6Q-Sabreauto-SPI_NOR & SD card" desc="Choose SPI-NOR/SD as media">
<CMD state="BootStrap" type="boot" body="BootStrap" file ="u-boot-mx6q-sabreauto-spi-nor.bin" >Loading uboot.</CMD>
<CMD state="BootStrap" type="load" file="uImage" address="0x10800000"
  loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" >Doing Kernel.</CMD>
<CMD state="BootStrap" type="load" file="initramfs.cpio.gz.uboot" address="0x10C00000"
  loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" >Doing Initramfs.</CMD>
<CMD state="BootStrap" type="jump" > Jumping to OS image. </CMD>


<!--burn the uboot to SPI-NOR: -->
<CMD state="Updater" type="push" body="$ flash_erase /dev/mtd0 0 0">Erasing Boot partition</CMD>
<CMD state="Updater" type="push" body="send" file="files/u-boot-mx6q-sabreauto-spi-nor.bin">Sending U-Boot</CMD>
<CMD state="Updater" type="push" body="$ dd if=$FILE of=/dev/mtd0 bs=512">write U-Boot to SPI-NOR</CMD>



Thank you!
