Hi, Anybody here is using AMC8548 board from STx.

Have you contacted STx? I believe they have a complete Linux Rapid IO kit, that includes an updated version of u-boot, specifically for this board. It could be useful to your progress.

I saw the mapping for RapidIO board to be at C0000 location. But that location does not show any valid data. I used command "md c0000" for this.

Does ccsr location play any part in this?

Of course it does. All of those registers are relative to the CCSRBAR.

I also tried using "md e00c0000" as ccsr location is e0000000.

Or am I missing anything.

Well, you should probably consider writing some software to do the necessary Rapid IO initialization and the testing you desire. There aren't enough hours in a week to manually peek/poke all of the registers necessary to do something useful. :-)

Thanks.
