Why do I get the "Unable to bind (112)" error message?

I have to build a system with two NIOS2 processors, each of them linked to its corresponding on-chip memory block by means of the reset and exception vectors, and some PIO's. This configuration must ...

First of all you mentioned that the two CPUs are sharing the same PIO, you must use mutex IP to control this hared peripheral and any other shared peripherals. Then tell me how you want to boot the NIOS II? I mean, are you creating a jic file to combine the sof file with the two HEX files? I prefer this way as it will solve any confusion that might happen.

BTW you can download the "Multi-Core NIOS processor example" from the link below and see how to have 4 NIOS processors running together and sharing the same peripherals.
