imx6ul-ddr configuration-imximage.cfg file

[surendradhobale]

Hello,

   I am working with imx6ul custom board. I have boot the device with emmc and have to initilalize the ddr.

I have seen imximage.cfg is one of the file where configurations are done.

Can anyone please give me more idea about the imximage.cfg file?

I mean which registers are their and what values i need to put ? How to modify this file if DDR coeffiecients are different?

Thanks,

Surendra

Hello,

  First, please try to get the memory stress test working.

i.MX6/7 DDR Stress Test Tool V2.60 

   Please use the following document how to configure DDR parameters.

Freescale i.MX6 DRAM Port Application Guide-DDR3 

 As for the imximage.cfg file, please look at Chapter 1 (Porting U-Boot from
an i.MX 6/7 Reference Board to an i.MX 6/7 Custom Board) of “i.MX_BSP_Porting_Guide.pdf”.

  Also, please refer to section 8.7.2 [Device Configuration Data (DCD)] of the

i.MX6 UL RM (IMX6ULRM, Rev. 1, 04/2016)

Have a great day,

Yuri
