You can't configure the sensor to output 320x240 without additional explicit cropping. If you really need a 320x240 output you should configure the sensor to output a 1292x972 image, and use the OMAP3 ISP resizer to downscale to 320x240. > I see 21.6mhz on clka. > I see that /OE is low, and /RESET is high. > I don't see anything on PCLK, or the data lines D0 to D11, which confuses > me. > > Output from yavta is here: http://pastebin.com/q0mB4ArN > > Does this sound like a hardware or software issue? Definitely software, the pipeline is not configured properly as explained above. -- Regards, Laurent Pinchart -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
