Hi,
We have a custom iMX6UL based board and we are trying to flash the board using mfgtool. The issue is it keeps looping to downloading images stage again and again. Details below
Original Attachment has been moved to: ucl2.xml.zip
Original Attachment has been moved to: MfgTool---Copy.log.zip
Hi
looping back may mean ddr issues, please run ddr test
https://community.freescale.com/docs/DOC-105652
and rebuild mfg tools firmware with new calibration settings obtained
from test using sect.6.2 Manufacturing Tool, MFGTool attached Yocto Guide.
Then replace new files in mfg tools ../firmware folder.
Best regards
igor

Hi,
Thanks for the quick response. Even after updating the ddr calibration settings and rebuilding mfg tools we still see the same issue. Below is the process of how we updated the calibration settings to see if we missed anything.
We ran the ddr calibration and the results we got are
MMDC registers updated from calibration
Write leveling calibration
MMDC_MPWLDECTRL0 ch0 (0x021b080c) = 0x00000000
Read DQS Gating calibration
MPDGCTRL0 PHY0 (0x021b083c) = 0x01540154
MPDGCTRL1 PHY0 (0x021b0840) = 0x00000000
Read calibration
MPRDDLCTL PHY0 (0x021b0848) = 0x40403E46
Write calibration
MPWRDLCTL PHY0 (0x021b0850) = 0x40405A56
We then updated these in the file
../build/tmp/work/imx6ulevk-poky-linux-gnueabi/u-boot-imx-mfgtool/2016.03-r0/git/board/freescale/mx6ul_14x14_evk/imximage.cfg
And then built using
bitbake u-boot-imx-mfgtool
bitbake fsl-image-mfgtool-initramfs
Replaced the new uboot and initramfs files into the mfg tools ../firmware folder
Did we miss anything here...
Appreciate your help...
