VCU pl-ddr ddr4 controller supported memory parts on zcu104

 

VCU pg252 doc(v1.2) states that the following sodimm memory parts are supported by vcu ddr4 controller in page 117:

X8 (KVR21SE15S8/4)

X16 (MTA4ATF51264HZ-2G6)

and in page 114 :

"RAM bus width selection- can be x8 (zcu104 evaluation board) or x16 (zcu106 evaluation board)"

based on this info, correct me if I'm wrong, it's only possible to use kingstone KVR21SE15S8/4 model on zcu104.

can this parts be substituted with another memory with the same configuration?

 

in our current setup we use a 8GB hynix-2133 module(512x16) which has the same configuration as MTA4ATF51264HZ-2G6 . but during boot time it freezes when trying to probe vcu decoder.

Hi @mksafavi 

 

Did you refer the following AR ?

 

https://www.xilinx.com/support/answers/69403.html

 

And, did you make sure CL, tRCD and tRP on Hynix's memory module ?

Also, did you make sure number of die on a memory chip ?

 

I guess some parameters are different between certified Micron's module and your current module.

I suggest you to make sure what I point out.

 

Best regards,
