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.

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.

"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?
Correct - 4.
