Eddy and anyone who may be able to help, I am currently working on an Omnivision OV5620 and have used the ov3640 driver as a starting point. I have the June 18( latest ? ) code from the gitorious git repo. I have thouroughly tested my i2c driver setup using a 500 Mhz oscilloscope and have configured the sensor to 640 x 480. The only mode this supports is RAW V4L2_PIX_FMT_SGRBG10 and I have that as the only available format. So far so good. Sensor powers, configures etc, etc. However when I run the sensor I get ISPCTRL: HS_VS_IRQ <6>ISPCTRL: OVF_IRQ <6>ISPCTRL: To test this I used the example code provided with v4l2 documentation. I have attached a complete log with all my added printk's set up as a poor mans stacktrace. Stuck trying to determine where to go from here, I feel like I am so close to getting an image.

I don't know what the problem might be with YUYV data - we get useful YUYV data without any changes to the ISP defaults. > However, to request RAW data, that simply uses the CCDC and bypasses all the

This will give you two bytes per pixel, at least in our case (although we have a 12-bit sensor cut down to 10 bits), so be prepared to throw out every other byte. > > Hope this helps, > > Eino-Ville (Eddy) Talvala > Computer Graphics Lab > Stanford University > > On 7/14/2009 9:49 AM, Zach LeRoy wrote: >> >> Hello Sergio, >> >> I spoke with you earlier about using the ISP and omap34xxcam drivers with a micron mt9d111 SOC sensor. I have since been able to take pictures, but the sensor data is not making it through the ISP data-path correctly. I know the problem is in the ISP data-path because I am configuring the sensor the exact same way as I have been on my working PXA system. I am expecting 4:2:2 packed YUV data, but all of the U and V data is no more than 2 bits where it should be 8. I know the ISP has a lot of capabilities, but all I want to use it for is grabbing 8-bit data from my sensor and putting it in a buffer untouched using the CCDC interface (and of course clocking and timing). What are the key steps to take to get this type of configuration? >> >> Other Questions: >> >> Is there any processing done on YUV data in the ISP driver by default that I am missing? >> Has any one else experienced similar problems while adding new sensor support? >> >> Any help here would be greatly appreciated. >> >> Thank you, >> >> Zach LeRoy >> -- >> To unsubscribe from this list: send the line "unsubscribe linux-omap" in >> the body of a message to majordomo@xxxxxxxxxxxxxxx >> More majordomo info at http://vger.kernel.org/majordomo-info.html >> > > -- > 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 -- 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
