I wonder if that is related to the issue I found with w1-gpio the other day? w1-gpio is given GPIO0 as a pullup pin by the BSP so it takes control of it for that purpose, possibly breaking the I2C bus as mentioned in your link Issue: https://github.com/raspberrypi/linux/issues/601 My fix is here: https://github.com/raspberrypi/linux/pull/602 I'm not loading the w1-gpio at present though so I don't believe it is causing the problem (In fact - at any point I can run mjpg-streamer and that will work!

I appreciate any thoughts at all :) I think next I'm going to have a look at gstreamer1.0-omx and see where that gets me...

I hate to mention this but it may have something to do with the the functionality of the component.
Try this: https://github.com/raspberrypi/linux/issues/435
Also something like strace or even 'sudo vcdbg syms | grep -i cam' would be useful if available of
the rootfs.
 

That's interesting. I wonder if that is related to the issue I found with w1-gpio the other day?

w1-gpio is given GPIO0 as a pullup pin by the BSP so it takes control of it for that purpose, possibly breaking the I2C bus as mentioned in your link

Issue: https://github.com/raspberrypi/linux/issues/601

My fix is here: https://github.com/raspberrypi/linux/pull/602

I'm not loading the w1-gpio at present though so I don't believe it is causing the problem

(In fact - at any point I can run mjpg-streamer and that will work! So I know the camera is OK...)

Sorry for this type of interaction. I am really busy with some other project.
If nothing works we could use OpenMax as you suggested to interact with the camera, but I still hope
this problem can be fixed.


No problem Alex. I appreciate any thoughts at all :)

I think next I'm going to have a look at gstreamer1.0-omx and see where that gets me...

Cheers,

Alex
