I use new verion on keil. I choose the LPC2468 device, I build a simple sample with the default Startup.s. The program get into a dead loop, it is waiting for mian oscillion locked. there is a dead loop wait for SCS::OSCSTAT ok, the simulation cann't generate this signal, so the program wait it deadly. Dose any configure need be set in keil? Or the code can just run in target board? Thanks
