Hello, I'm trying to create a submodule in EDK that contains microblaze and a custom core that basically just passes some of the OPB signals through to the top:
--forward signals CLK

Check out the Xilinx Tech Exclusive at :

I went thru it and got a peripheral to work using PPC (not MicroBlaze). It goes through some steps about simulating the OPB interface. You might want to investigate the use of ChipScope Pro too.

After further consideration, IIRC, the mentioned tech exclusive did not read back data, it is an LCD display.

Thanks for the advice. I was able to get it working, turns out my problem was a timing issue on the IP2Bus_Ack line.
For the interrupts I figured out that I could not just set the global interrupt handler in the Microblaze S/W settings in EDK, but had to do it explicitly by adding the line: microblaze_register_handler(int_handle, (void*)0); to my setup routine.
