Subject: OMAP3 ISP DQBUF hangs
Date: Thu, 15 Aug 2013 14:15:28 +0000 (UTC) [thread overview]
Message-ID: <loom.20130815T161444-925@post.gmane.org> (raw)
Hello,
I'm working with an OMAP3 DM3730 processor module with a ov3640 camera
module attached on parallel interface. I'm using Linux 3.5 and an
application which builds the pipeline and grabs an image like the
"media-ctl" and the "yavta" tools.
I configured the pipeline to:
sensor->ccdc->memory
When I call ioctl with DQBUF the calling functions are:
isp_video_dqbuf -> omap3isp_video_queue_dqbuf -> isp_video_buffer_wait ->
wait_event_interruptible
The last function waits until the state of the buffer will be reseted
somehow. Can someone tell my which function sets the state of the buffer? Am
I missing an interrupt?
Best Regards, Tom
