Freescale i.MX31 floating point   
Does QNX support the Freescale i.MX31 vector floating point unit?

We're looking for a replacement for the pxa270 and sure could use the floating point unit.

TIA

Yep, gcc 4.2 toolchain has support to do ARM vfp.

Re: Freescale i.MX31 floating point   
BTW, the compiler options you would want to use would be:

-mfpu=vfp -mfloat-abi=softvfp

Re: Freescale i.MX31 floating point   
No problem. Rereading your question, I'm not certain if you were strictly speaking about VFP support from the Tools or 
the OS. I assumed it was the tools because this is the tools forum.  

You would also need the ARM v6 procnto for VFP support.

Is procnto v6 released or still beta?

IOW, what needs to be downloaded to get this support?

Thanks again.

It will be released with 6.4.0

Note that you'll also need a startup built with the 6.4.0 (head branch)
libstartup.a to ensure it sets everything up for procnto-v6 operation.
I don't know the BSP release schedule though...

Re: Freescale i.MX31 floating point   
Great, Thanks!

It looks like the required stuff can be downloaded from the Trinity build.

Hopefully that will be suitable for our MX31 evaluation benchmarks.
