Hi everyone,
I'm developing a new board based on the IMX6Q.
We have make the DDR's clock root from 528M successfully.The uboot's version  what we use is 2009.08.
We want to make DDR running at 400M for some reason.



We have read how to change DDR clock of i.mx6 . Many efforts have been tried according to the thread.

but the u-boot can't start up.


Is the DCD table as defined in the uboot source file "board/freescale/mx6q_sabresd/flash_header.S" my only point for DDR configuration?


By the way, could I change ddr clock after boot ?








Does anyone know what I am doing wrong? Any clue about that error?


Can you help us ?
Yours sincely.
