Reset problem


I have downloaded the E20 core and is now trying to get it to run. Unfirtunately I don’t have access to the simulators that are used in the examples, so I have not been able to test them.

THe first thing I wanted to do was just to take the processor out of reset and verify that it can fetch an instruction. Since I did not find any memory interface in the entity I assumed all memory is on the AHB-bus.

When I trie to simulate the SiFive_CoreIPSubsystem I get ‘X’ on the AHB bus when I deassert reset.

I thougth that the processor would start to access the AHB-bus to fetch the first instruction.
Do you have any idea what signals I have misinterpreted?

Can you help me with what signals I’m setting to the wrong value.
