I am trying to get the SABRE Lite board working with my parallel camera (OV5642 based Nit6X_5MP module), both from Boundary Devices:
http://boundarydevices.com/product/nit6x_5mp/
I am running the Yocto Dizzy pre-built image from Boundary Devices which boots up fine.
I was trying to get the camera input to be displayed on the HDMI monitor, but it consistently fails. The "ov5642_camera" and "mxc_v4l2_capture" modules are loaded per the console:

My Gstreamer command is as simple as it gets:
gst-launch mfw_v4lsrc ! mfw_v4lsink
but as the console shows, it fails with the error "ERROR: v4l2 capture: mxc_v4l_dqueue timeout enc_counter 0".

The behavior changes if I specify "capture-mode=5" or "capture-mode=6", but it fails with a different error.

Any hints of where to look for the trouble would be appreciated!
