Has anyone done any experiments with running Maple programs on a Free/Libre/Open Source Cortex-M3 simulator/emulators?
I'd like to try getting some folks to do Test Driven Development, and I thought a simulator might be a very useful tool.
I believe QEMU supports Cortex-M3 (thumb) instructions, though it won't have the peripherals.
I'd like to hear any experience of FLOSS or commercial simulators/emulators which support Cortex-M3.

gbulmer - did you get any further with this at all?
I'm just starting to look at doing some TDD using my Olimexino-STM32 and I'm trying to work out how to get started (at the moment it seems a mixture of Eclipse and Unity is the most likely way, but I'm still STFW).

iainism - no I haven't made any useful progress.
I believe Keil's free (restricted) version has an instruction level simulator, but I didn't figure out how peripherals were handled.
This link has some instructions on using QEMU for Cortex-M simulation http://cgi.cs.indiana.edu/~geobrown/stm32/Main/Simulation
Crossware have a simulator, but is is far from free: http://www.crossware.com/shop.htm?chip=Arm#Stm32ds
I think I could write a reasonable Cortex-M3 instruction level simulator, I think writing a gdb server for the simulator is practical too. IMHO the harder part is simulating the hardware peripherals in a useful way.
Is that Unity the games engine?

I have been running STM32 code on qemu, without peripherals that is. http://www.seeedstudio.com/wiki/DSO_Nano/Qemu_gdb

gbulmer and tormod, thanks for the links, I'll take a look through them this afternoon.
My mention of Unity was ambiguous to say the least - I meant the Unity Unit Test framework: http://throwtheswitch.org/white-papers/unity-intro.html
