Hi all,
I met a wired BlockRam connection error when I tried to build a mutilple processors system using EDK. Hope anyone can give me some hint.
Here is the background. With the EDK, we can create a single processor (MicroBlaze or PowerPC) at ease. Based on the single Processor sytem, I added those IPs, including the processor (MB or PPC), the bus , BRAM memory, memory controller and some pherpherals. I connected them in the same way the single processor system do, which needs some modification in the mhs file. There is no connections between two processor system. In the Build process, the project passed the syntheis and failed in the map. The message is this:
