Hi, I trying to get the mt9p031 to work on the Overo board. So far I have it working in the Beagleboard xM, and now I have sort of ported/used the same files to get it to work with Overo. My problem now is that when I probe the camera board (LI-5M03 with an adapter board in between providing extra voltage levels) it seams fine.
OMAP3ISP loads without any bigger error but the mt9p031 driver can't find the device, but it does not seam to be a driver problem rather a board problem. I think this since I've been debugging with "i2cdetect -y -r 3" to scan the bus for the camera. Most of the times I get nothing, but a couple of times (out of hundreds or more, I used a while loop with i2cdetect and then a sleep 1) it showed up with it's address. I think it happens when I just inserted the board but I'm sure or if I get it into some "weird" state just adding it. It could be a contact error but I have a felling it is something else I have missed. Some pin configuration or something that stops it from working. Do you have any tips on how to debug further or on what might the my problem? I have tried to lower the i2c speed to 100 KHz but it did not seam to make any difference. dmesg: http://pastebin.com/MG7G7v8h board-overo-camera.c: http://pastebin.com/wvTmKk89 board-overo.c: http://pastebin.com/1cc9PkGE Output from i2cdetect: http://tinypic.com/r/huh8bb/5 -- Regards, Robert Åkerblom-Andersson -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
