Hi all,
I programmed a simple blinky program for STM32f429. I tried it on the STM32F429-DISCOVERY development board and it worked just fine. However when I tried it in the simulator, every other GPIO related registers got set (can be seen in the GPIO register panel), but the ODR register remained at 0 when some pin was turned on. However I was able to receive interrupt from SysTick under simulation mode. Is it a bug in the simulator? I can upload the project if anybody is interested. The program relies on CMSIS and STM32F4 peripheral libraries.
Another issue I faced was that I received no 'write' permission warning whenever I ran the program. I have to manually enter MAP command to resolve it. Why memory-map registers for in-built peripherals were not properly mapped?
SysTick is a function of all Cortex-M4 processors, what isn't provided in the simulator is hardware specific to a particular vendor, and peripherals they attach to the core.
Error 65 means what you're doing isn't supported.
@Westonsupermare Pier, yes - you're right :-)
@kaos ad - Just a small note in addition - see also "Simulation of Cortex-M Devices": http://www.keil.com/support/docs/3726.htm
Thanks guys. Really appreciate your prompt reply.
