[misakamikoto]

Hi All:

     I'm working on changing ddr4 params on ls1043ardb,but I can't find the position where ddr4 params stand.Can somebody tell me where the dde4 params store?Txs!

DDR4 params location in different place , timing params locate in : board\freescale\ls1043ardb\ddr.c    ddr_raw_timing[], udimm params locate in board\freescale\ls1043ardb\ddr.h  udimm0[]

Usually u-boot provides DDR configuration on the board.

Change u-boot configuration using u-boot source code.

U-boot configuration file is located in the u-boot source folder: /include/configs. This folder contains the .h files for the different boards.

Find the ls1043a_commn.h file and CONFIG_SYS_FSL_DDR4 definition in this file.

This file is available in the attachment.

Have a great day,
Pavel Chubakov

Txs,Pavel.But I mean I'm looking for the ddr4 config params header file,just like ddr timing or something else.I mean I want to change the ddr controller register value.So I think there must be a file just include this reg setting,doesn't it?
