Hi,we have 2 P2020 boards,My question is that can we connect the two boards with rapidio directly without a switch?Does this need to set master or agent?thanks.
Yes, it is possible to connect two P2020 through sRIO. One device should be configured as a host and another as an agent.
Thanks for your reply.some details I wish to know,and wait your reply.
if there is only one way to configure as a host or as an agent by pull up/down resister on POR(Power on Rest)?can we do that by writting register POR Boot Mode Status Register(PORBMSR)?
Another question is that if there is no need to configure a host and an agent when 2 boards are connected with a switch?

Yes, it is possible.

One processor in the system has to be a host to discovery other agents.
Useful reference could be "AN2932 - Serial RapidIO Bring-Up Procedure on PowerQUICC™ III":

I will read the reference AN2932.pdf.
