[Qemu-devel] Better Cortex-M support?

[Liviu Ionescu]

Hi! 

I'm currently maintaining the GNU ARM Eclipse plug-ins 
(http://gnuarmeclipse.livius.net/blog/), and I'm considering, for the mid-term 
future, adding a new debugging plug-in to run certain tests under un emulator, 
and the first choice was QEMU.

Do you know if there are any plans to improve the Cortex-M support? As it is 
now, for my needs, I would consider it barely usable.

My requirements would be:

- Cortex-M3 support, as complete as possible, including SysTick and other 
system peripherals.
- full semihosting support
- full integration with GDB

For future versions, support for M0/M0+/M4 would also be interesting.


The only branch that I tested and looked partly functional was from Andre 
Bechus (https://github.com/beckus/qemu_stm32), but this is a specific STM32 
port, and I'm interested in a more generic Cortex-M emulation.


Do you know of any other branches that improve Cortex-M support?

Is there anyone else interested in contributing to such development?


Regards,

Liviu
