How to edit u-boot according to the DDR calibration values ?

Dear All,

 

1) I have done DDR stress test and calibration using DDR stres test tool v2.60 for my iMAX6 Quad processor based custom hardware design. And I'm referring to the nitrogen6X uboot files and which files and locations should I edit using calibrations values ?

 

2) Initially I have an understanding about doing this according to the following procedure.

We should edit ;

# include "ddr-setup.cfg"

# include "1066mhz4*128*16.cfg"

# include "clock-cfg"

files. But according to my understanding "ddr-setup.cfg" and "clock-cfg" are generic files and we don't have to edit those files. As well as finally we need to recompile the defconfig files. So is this procedure correct ? Do we have to edit more than this ?

 

3) In some forums mentioned that we need to edit flash_header.S file. What is this ? I couldn't find such file in nitrogen6X u-boot.

 

I must be thankful to you if you will kindly advice me on this.

 

Regards & Thanks,

Peter.
