Help needed with newer DMAI on omap3530

Howdy.

I've had some code working fine in the past.  I've recently upgraded to DMAI 2.10.0.1 SVNr570 (from 423) and it no longer works.  (I am building the overo OE branch from gumstix)

I see that with this update Display_Attrs_O3530_VID_DEFAULT changes the display device from /dev/fb1 to /dev/video1 -

i don't have the latter, so i updated the my structure with

       dAttrs.videoOutput = Display_Output_DVI;
       dAttrs.displayDevice = strdup("/dev/fb1");

Now I'm getting this in my CE_DEBUG=2 log:

     ti.sdo.dmai - [Framecopy] not implemented

I don't understand what is going on.  No obvious help in the release notes.  Do i need to put something different in my /sys/devices/platform/omapdss sysfs?

Appreciate any pointers!

Thanks,

Andy

    Hello,

    DMAI  has very highly depedency on TI DVSDK's.

    Its possible that overo folks are not using PSP Linux kernel releases and  have applied some extra DSS or ISP patches. You may need to read DSS docs for your kernel release and  update DMAI accrodingly.

    Thanks

    More specifically, if the ISP resizer kernel module isn't configured in your kernel, DMAI will return "not implemented" as you describe above.

    Niclas and Brijesh - thanks for your prompt replies!

    I had been running the PSP kernel (2.6.32 git 5fc29e7b), but changed to the overo 2.6.34 for improved wireless support.

    Am I just stuck in the middle here, with DVSDK on the PSP kernel and libertas wireless on the overo kernel?

    Is the 2.6.32 PSP kernel above the one i should be running for the "best" DVSDK experience?

    Thanks!

    The DVSDK is only tested on the 2.6.32 PSP kernel, you would need to port the wireless drivers to 2.6.32 to take advantage of them until the DVSDK is updated to a newer kernel.
