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.

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.

Yes, thats right,

I couldn't manage to debug the system with  DDR RAM.

I ll be very pleased if you can help me with the 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.
