<DIV dir=ltr align=left><FONT face=Arial color=#0000ff size=2>Hi,<BR> I
have found <SPAN class=520283006-24032007>two </SPAN>ways to do
that.Thought to reply in case anybody else needs the info.</FONT></DIV>
<DIV> </DIV>
<DIV dir=ltr align=left><FONT face=Arial color=#0000ff size=2> 1. Program
ROWAR, ROWBAR and ROWTAR registers of MPC8548 for attributes and the address
locations along with the size of the ATMU window<SPAN class=520283006-24032007>
through U-boot</SPAN>. Then try to read or write into the window locations. This
will generate the outbound packets on the rapidio interface.<BR> This also
needs the LAWAR and LAWBAR window setting to route the traffic to RAPIDIO
interface. The code for Rapidio window setting being the "1100"</FONT></DIV>
<DIV> </DIV>
<DIV dir=ltr align=left><FONT face=Arial color=#0000ff size=2> 2. Other
way is to program the DMA controller registers and set MR[cs] bit to 1. This
happens only if the other SAR, DAR, SATR and DATR plus BAR registers are
correctly programmed. The details can be found in the MPC8548 family reference
manual.</FONT></DIV>

<P>Hi,<BR> Anybody here is using AMC8548 board from
STx.<BR> I am working on the board and the problem is that I don’t
know how exactly can one see the RapidIO registers of the
board?<BR> <BR> 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.<BR><BR> Does ccsr location play any part
in this?<BR> I also tried using "md e00c0000" as ccsr location is
e0000000.<BR><BR> Or am I missing anything.<BR> I also
want to know how exactly can one generate the RapidIO traffic. I want to
validate RapidIO controller on FPGA connected to
AMC8548.<BR><BR> Please
help<BR><BR>Thanks,<BR>Rajendra<BR><BR></P></DIV></BODY></HTML>
