Hi, Check the following log...
The crash doesn't seem to directly related to this patch. Did you get any error while applying the patch. You seem to have not build tvp514x. So no sub device available to register in vpfe capture. So enable it. It is part of encoder/decoder menu... vpfe_init vpfe-capture: vpfe vpss master clock enabled vpfe-capture: vpfe vpss slave clock enabled vpfe-capture vpfe-capture: v4l2 device registered vpfe-capture vpfe-capture: video device registered vpfe-capture vpfe-capture: No Subdevice data vpfe-capture: vpfe vpss master & slave clocks disabled Murali Karicheri Software Design Engineer Texas Instruments Inc.
