test peripheral example in xilinx XPS

[bhatti]

Hello all

I am using xilinx platform studio (XPS) for testing my FX12 minin modul
development board and facing some problems.

Using base system builder, i select only RS232 and Mini module GPIO led
and two examples were created,one test memory and second tes
peripheral.Test memory resides in BRAM while test peripheral in DDR SDRAM.

I downloaded bit file to my board successfully for both memory an
peripheral examples one by one using xps download bitstream but problem i
that test peripheral example shows nothing (test memory example show
correct results on hyperterminal).

I am quite new to xps and fpga, kindly guide me what can be the problem?
guess it has to do something with executing code from external DDR SDRAM?

Thanks in advance

Downloading the bitfile to the FPGA will not put the test peripheral
program into DDR memory for you. The simplest thing you can do is to
regenerate the linker script to put that program into BRAM memory so
that it will be downloaded with the rest of the bitfile.

What version of EDK/XPS are you using, and are you also using SDK?

Thanks for your response.I am using EDK 10.1. No, i have not still use

SDK.Using BRAM i think i will face limited memory problem, secondly i wan
to learn how to execute my code from external DDR SDRAM.



Thanks in advance

You can load the code into DDR sdram using XMD.
If you have a compact flash system, an ACE file can load DDR SDRAM for
you.
If you have non-volatile memory, a boot loader program in BRAM can
move the executable from nvmem to DDR.

You should read the tutorials and manuals.

If there is a tutorial (with example) covering this typical issue, pleas

let me know

Have a look at this.
http://www.xilinx.com/support/documentation/boards_and_kits/ug494.pdf

I searched and found this document just to see how difficult it was to
find.
I found it in 5 minutes.
