DDR3 Porting Problem on imx6ULL

[guochgz]

hello,

       I am using SkHynix H5TC2G63GFR-PBI DDR3 on imx6ull, there is some question about DDR3 Porting, Is there someone can help me? thanks first. 

       Q1: Is there a special DDR3_Script_Aid tools for imx6ull? I have download a imx6ul aid that  the name is <I.MX6UL_DDR3_Script_Aid_V0.02.xlsx> from this community

https://community.nxp.com/docs/DOC-329899

. is this ok? 

       Q2: how to setup DDR3_Script_Aid? there are some item which I have no idea.

Q3: the last one about NXP DDR Test tool , What is the Value about MR1 Values(Hex)? 

[Yuri]

Hello,

   Customers can use the following tool:

“i.MX6ULL_DDR3_Script_Aid”

https://community.nxp.com/docs/DOC-333791

MR1 value should be the same as in the initialization script.

Have a great day,

Yuri.

Thanks Yuri.

"MR1 value should be the same as in the initialization script." What does this mean?  

I have found this in ddr stress tools dir. 

so MR1 Value should be 0004?
