I have a custom board based on i.MX6ULL (MCIMX6Y2CVM05AA 14X14) with 4 GB DDR3 RAM & 4 GB eMMC. I am trying to setup u-boot for the board. Shall i be changing the "./board/freescale/mx6ull_ddr3_arm2/imximage.cfg" file with the DDR calibration coefficients? Or shall i be changing "./board/freescale/mx6ullevk/imximage.cfg" in u-boot? Can anyone guide me with the detailed changes i need to make to bring up u-boot on this custom board? I am using mfgtool2 to flash using "mfgtool2-yocto-mx-14x14-arm2-emmc-ull.vbs". Am i using mfgtool2 correctly? Much needed help!
Hi Pankaj
DDR calibration coefficients should be put in folder for corresponding
board, which was used as reference for custom board. If it is i.MX6ULL EVK
then ..mx6ullevk/imximage.cfg. For changes one can look in Porting Guide document
included in linux documentation package on
Also for using mfg tool it is necessary to use vbs script file corresponding to used reference board.
Best regards
igor

i'm also puzzled by this...
Hi,
Could you try this command "bitbake -C compile u-boot-imx" ?
Hope this help you.
Hi igorpadykov,
I have modified the file imximage.cfg in the folder ~/imx-yocto-bsp/build-fb-imx6ull/tmp/work/imx6ull14x14evk-poky-linux-gnueabi/u-boot-imx/2018.03-r0/git/board/freescale/mx6ullevk with parameters given from the DDR3 calibration tool but when I run bitbake core-image-base, the core-image-base-imx6ull14x14evk.sdcard.bz2 and u-boot-imx6ull14x14evk.imx files are not recompiled.
In the iMX BSP Porting Guide Linux (chapters 3.2.1 and 3.2.2), it is just said "If the DDR configuration (board/freescale/<customer_board_name>/imximage.cfg) is modified successfully, you can compile and write u-boot.imx to an SD card."
What is needed to make a new u-boot.imx file with updated DCD values?
Thank you for any help.
