How to use qemu simulate Cortex-R4

Asked by gangster

Now I'm trying to simulate Cortex-R4 CPU in qemu, but there is no board related to Cortex-R4, who can show me a way how to get the sample code for bare metal Cortex-R4, including the ASM code, and the qemu model for Cortex-R4.Many thanks!

Have you looked at the GNU ARM Eclipse project in case the QEMU and example projects that it provides are of any use in this context?

http://gnuarmeclipse.github.io
http://gnuarmeclipse.github.io/qemu/download/
http://gnuarmeclipse.github.io/templates/cortexm/

Hope this helps.

Hi,

Are you looking for startup code or a sample application? The release ships with some sample startup code for M-devices. This should give you some hints to port them to R.

Thanks,
Tejas.

Hi Tejas,

Thank you to answer my question, actually I'm looking for startup code fo Cortex-R4 serial, I just need one common code base, which can bring CPU up, jump to main(), that's all, thanks!

Can you help with this problem?
