Running program on DDR RAM

[ Edited ]

Hi,

 

I use Digilent Atlys board.

 

When I want to run my code on DDR RAM, I also upload my MFS data (file system) into it. I observe the operations over XMD and computer first downloads MFS and then executable part. But I couldn't read anything from file system.

 

I wonder that if system does reset the DDR memory before loading data.

 

Could you help me about this?

 

Thank you.

Yes, XMD will issue a reset by default with the dow command.  There is an option to disable this behavior.

Thank you for your answer.

 

I switched the option of debugconfig command to disable system reset but it didn't work.

Re: Running program on DDR RAM

Hi,

 

Can you provide me a Xilinx ISE project which has a Microblaze and a DDR3 controller for Micron MT41J64M16LA device?

 

Spartan 6 XC6SLX45T is what i m using.

 

(My board is a custom board http://www.enterpoint.co.uk/raggedstone/RaggedStone_User_Manual_Issue_1_02.pdf and i face some problems with executing code from DDR3)

 

Thanks

Hi,

 

I think you need both Board Support File for XPS and a Board Support Package (BSP) for XSDK.

Re: Running program on DDR RAM

I don't have any information about the board you worked on. You should consult the technical stuff at enterpoint. However, if you want to implement an RTL-level design, there is no need any Board Support File or Board Support Package.
