I'm now using this core to accompllish communications between 2 ML507 boards. But after I finished the codes as indicated by the User Guide, when I'm trying to send a packet from board A to board B, I find when the time the packet sent out from A, the operating system will die. And I find board B doesn't get any packet from A. Does the communication between 2 PCI Express devices need something else such as DMA?
The 2 boards are connected to a switch chip( produced by IDT, name is 22H16), and this switch is connected to a x86 system.
