Using MFGtool(UUU) on IMX6DL in Linux

I am pretty new to this area so please bear with me.


I have an IMX6DL board and I want to flash a Linux image through USB.

Originally, I flash my image using a windows version of mfgtool. This takes in a "ucl2.xml" file which contains all the flashing and partitioning commands. This works but I am trying to transition into using Linux to do everything.

I downloaded UUU ( on my ubuntu 16.04 machine. I found a table of direct conversion from ucl2.xml to UUU script (HERE).


Using the conversion table, I managed to convert the first few lines from:

<CMD state="BootStrap" type="boot" body="BootStrap" file ="mfg/u-boot.imx" ifdev="MX6D">Loading U-boot</CMD>
<CMD state="BootStrap" type="load" file="mfg/zImage" address="0x12000000"
        loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" ifdev="MX6D">Loading Kernel.</CMD>
<CMD state="BootStrap" type="load" file="mfg/paladin-mfgtool-initramfs" address="0x12C00000"
        loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" ifdev="MX6D">Loading Initramfs.</CMD>
<CMD state="BootStrap" type="load" file="mfg/imx6dl-custom.dtb" address="0x18000000"
        loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" ifdev="MX6D">Loading device tree.</CMD>
<CMD state="BootStrap" type="jump" >Program eFuses and jumping to OS image.</CMD>


To (uuu script):

uuu_version 1.2.39


# flash u-boot
SDP: boot -f mfg/u-boot.imx


# flash initramfs
FB: ucmd setenv fastboot_buffer 0x12C00000
FB: download -f mfg/my-mfgtool-initramfs


# flash device tree blob
FB: ucmd setenv fastboot_buffer 0x18000000
FB: download -f mfg/imx6dl-custom.dtb


# flash kernel
FB: ucmd setenv fastboot_buffer 0x12000000
FB: download -f mfg/zImage
FB: acmd booti 0x12000000 0x12C00000 0x18000000



When I run my script, u-boot does get flashed but is left waiting for the device to reload:

On the other hand, the device gets a "Bad Linux ARM zImage magic!" error and gets stuck

I tried setting some required flags in my u-boot defconfig file to follow this wiki page (HERE) but still no luck.


I am really stuck so any inputs would really be helpful (perhaps a slightly different approach?).
