Hi,

Still no luck getting the v3 patch working.
I did go back and re-test the first v1 patch that Javier released.
This works fine with the same version of media-ctl and yavta.
So it isn't either of those programs that is causing the problem.

Must be something else.

Will wait and see how Koen goes.

Cheers,
Chris

Hi guys,

It would be great if I can help you with MT9P031 as I'm interested in
faster integration of this module to the mainline. Thanks.

P.S. One question, why your patches are completely different from
Aptina's drivers? What your implementation is based on (I guess on
Guennadi Liakhovetski's driver)?

Cheers,
Max.

It is. For 2.6.39 + v3 of Javier's patches you need a current media-ctl
version unpatched. Interestingly, the new yavta version didn't work for
me, but maybe I've done something wrong. The old (patched) version did
work though.

Must be something else.

Will wait and see how Koen goes.

Thanks

I'm still stuck in "isp did no go idle" land, so even if yavta works, I can't get any output. It did output 3 frames to disk a few days ago, but that got deleted on reboot :frowning:

I don't know guys what to tell you.
I use kernel 2.6.39 + last version of my patches + old patched yavta
version (http://download.open-technology.de/BeagleBoard_xM-MT9P031/).

Guennadi, did you manage to get it working?
I'm preparing new patches for kernel 2.6.39 which I think should be
ready for submission. I'll send them during the morning.

Thank you.
