It could be that the other CPU is running but the hardware accelerator might be stuck. For that issue I would try to debug it separate from the system ID problem. I would also debug it by keeping the non-C2H CPU idle while you are trying to figure out what is happening.

For the system ID issue I would compare the base address in system.h for the sysID component to what you see in the SOPC Builder UI. Reading back 0xFFFFFFFF normally means that the wrong location is being accessed during the system ID check. So your system might not be built with the same system ID base address as the tools are expecting to find it.
