Hi

The MMU core freeze at startup (it doesn't start at all).
It reminds me a previous problem with an infinitite loop in the main CPU loop.

I've tried to start from the non MMU conf (it's OK) and activate the MMU + reboot from the gui (it freeze)

I've tried also to boot directly with the MMU (with hatari.cfg) : it freeze too

In my case, I see that falcon boots until it reaches the memory test, so there's a problem at this moment, I may have forgotten sthg while merging the new cpu part.
Does it also stops at memory test for you ?



OK, it's now fixed ; as discussed with Toni, the run_mmu030 functions needed some changes to count cycles depending on whether cycle exact mode was used or not, as the opcode handlers don't return a number of cycles in CE mode.
