Adding MPMC to project. ML403 SDRAM (HYB25D256160BT-7F) not in parts list??

Hello,

 

When I add the MPMC to my project for the ML403 board and try to configure it, the [edit] DDR [/edit]SDRAM part is not listed in the drop-down list labeled "Part No."  Am I missing something?  Is the ML403 part not supported by the MPMC?

 

It is worth noting that if I launch BSB and start a new project, when choosing the peripherals for your project there is an option for adding SDRAM. If you check this box and continue through with BSB, after your project is built, if you open the configuration window for MPMC you see that "Part selected" is in fact "HYB25D256160BT-7".  How did BSB get this part selected?

 

Anybody have any idea how I can configure MPMC for this part?

 

Thanks!

Hi ,

 

Isn't HYB25D256160BT-7 a DDR device?

But you mentioned in your first post that you were listing SDRAM parts.  Can you calrify that?

My apologies for the confusion.   The part number which I'm looking for in the drop down list, HYB25D256160BT-7F, is not there.  This part is a DDR SDRAM chip.

 

Note: I've edited my original post to say "DDR SDRAM".

Hi,

 

I did a quick test with 10.1 SP3. I can see the device from the drop down menu. 

 

Generally speaking, all of the predefined devices can be found in mpmc_memory_database.csv file, which is located in the \data folder of MPMC pcore.

 

If it's not listed in your MPMC GUI, I'd suggest you check out this file first and see if it's defined there.
