By 'works under model debugger' do you mean: * works if all single stepped * works if you just hit run * works when model debugger is debugging the isim_system * works only if model debugger is debugging a DLL model ? If all the parameters are the same then it should be equivalent. The only thing that springs to mind is that host load addresses will end up different and maybe I messed something up in the semihosting code with a signed/unsigned comparison? There's some tracing plugin support for the models which you should be able to use to dump an instruction trace in both cases and compare, which is probably just about tractable for a problem this early in boot. -- PMM
