How the host ID is set on your host board? Normally rio_enum_host() should increment next_destid in your case. >Another thing is that the agent is now hanging on the discovery process. Make sure that you have the MASTER bit is set in agent's GCCSR register (0xC_013C). If your board uses HW config switches to set host/agent mode this bit will be 0 for agent. For quick test you may keep both boards in the host mode - the current RIO implementation relies on "riohdid=" command line parameter instead of HOST bit.
