Ok, this is very strange. I found that disabling a bunch of checkboxes
on the SYSTEM page caused the remaining faults to disappear and the
project runs properly.

Narrowing them down, it appears that enabling either 'prefetch mode' or
'cycle accurate mode' (or both) will break my project. The other
checkboxes don't seem to contribute to the problem.

The main difference between this project and BadMooD is use of the FPU,
mainly within C code. I didn't see these issues with BadMooD.

Not sure if that helps make sense of whats going on.


just to be sure, what is your cpu settings when you get problem ? Is this 68040, 68060 or 68030 ? And what FPU setting do you choose in each case ? (for 68040 and 68060, FPU will be forced to internal if it's != NONE)

does it always work in 68030 mode with CE or prefecth and crash only in 68040/60 mode ?
