Hello community,
I tried to use my ov3640 camera along with my gumstix overo board and the
linux kernel 3.10. So for that I added the appropriate lines into the
board-overo.c file, but when I use "i2cdetect" after startup I get the wrong
output:
root@overo2:~# i2cdetect -r 3
WARNING! This program can confuse your I2C bus, cause data loss and worse!
I will probe file /dev/i2c-3 using read byte commands.
I will probe address range 0x03-0x77.
Continue? [Y/n] y

DMESG tells also that the driver couldn't be registered of the ISP. Can
someone help me? Did I forget something to register the ov3640 on the ic2 bus?
Regrads, Tom
