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 (https://github.com/NXPmicro/mfgtools) 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:
uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.3.154-0-g47ddef5
Success 0 Failure 0

Okay

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?).
