Hi all,

I am trying to simulate the basic Blinky program under Keil's simulator (MDK 4.60, with the addon for LPC800), but I keep getting error messages like:

*** error 65: access violation at 0x40048080 : no 'read' permission

Any R/W access to other registers cause such errors, even data registers like LPC_GPIO_PORT->W0. This behavior makes configuring the device useless. I also noticed that no peripherals are available for viewing in the debugger.

Am I missing something, or is it too early to get an actual running environment for the LPC800 family? Hopefully, the code is being generated correctly. In fact, I'll have a board to check that out this coming week.

Thanks for any pointers,
