Honored ContributorI have two ArriaII devkits, and the kits communicate with each other by rapidio(1.25Gbps). But I found the rapidio core on both kits are not initialized. The PORT_UNIT register's bit was always asserted.
Can anybody can give me some suggestion? Thank you!
Honored ContributorThe kits use different project base on SOPC. One is operated by niosii, the other is operated by pcie bridge.
I found that the PORT_UNIT register's bit would be deasserted when the two kit use the same project.Honored ContributorIt works now! Because the rate is different from each other. Sometimes the baudrate you set in sopc megacore isn't the same as the rate in "Configure Transceiver ...", we should confirm both of them.
