different drivers, and I really hoped its new version will work out-of-the-box in my setup (pcm037 with a mt9t031 camera). Unfortunately, it didn't. I've spent more than a full working day trying to get it to work, but I didn't succeed so far. It works with the on-board rtc, but it doesn't work with the camera, connected over a flex cable.
What problems are you experiencing?  I've been using versions of Darius'
driver for a while now with no problems on my system.

I couldn't read camera ID register during probing. As I mentioned, the camera is connected over a, hm, limited-quality self-soldered (by professionals) cable, and I have to reduce bus clock to 20kHz. Has anyone tested this driver with lower frequencies?

yes, I tested this with low frequencies (tens of kHz) and high freq. (400kHz).


Thanks
