select() timeout in video capture example
I'm trying to use a dm355-leopardboard to capture images.
When I execute the capture example from the Video for Linux Two API Specification: Revision 0.24 (http://v4l2spec.bytesex.org/spec/a16706.htm), it always time's out on the select() call. I'm not sure where to start looking for the cause of this problem. The ccdc and camera are passing registration.
[ 2.020000] vpfe_init [ 2.020000] vpfe-capture: vpss clock vpss_master enabled [ 2.030000] vpfe-capture: vpss clock vpss_slave enabled [ 2.040000] vpfe-capture vpfe-capture: v4l2 device registered [ 2.040000] vpfe-capture vpfe-capture: video device registered [ 2.050000] mt9v113 1-003c: Detected a mt9v113 chip ID 2280 [ 2.170000] mt9v113 1-003c: mt9v113 1-003c decoder driver registered !! [ 2.180000] vpfe-capture vpfe-capture: v4l2 sub device mt9v113 registered [ 2.190000] vpfe_register_ccdc_device: DM355 CCDC [ 2.190000] DM355 CCDC is registered with vpfe.
Furthermore, by inspecting the electrical interface to the camera, I have verified that the camera is transmitting pixel data.
What things would cause select() to timeout? Should I look for something in the drivers?
I'm using kernel version Arago/2.6.31+2.6.32-rc2-r52+gitr.
Thanks,
