Hi Dan, Thanks for replying. I got to know the address I'd be looking at to find the configuration space of RapidIO. (Actually I was looking at address e00c0000, and that was the correct location of configuration space) In case of STx support it comes very late for me as I am working with +5.30 GMT. The problem I am facing with this is that very few people I find working on RapidIO of MPC8548. On freescale website as well, there is very little documentation about how to deal with RapidIO (Regarding RapidIO packet sending and receiving.)

Thanks, Rajendra

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.
