Inno-maker ov9281
Posted: Wed Nov 25, 2020 12:22 pm
I'm trying to use the board with two ov9281 cameras from inno-maker. It's not going well. I can't even make one work, which I find very odd. The stereopi board works fine with the v2 camera. Also, both ov9281 cameras work fine with a raspberry pi 4 and pi-zero. So, I'm thinking that the issue comes down to something going on at the device-tree level. I'm digging, but hope that someone here has some experience with the cameras already: The camera is here: https://www.inno-maker.com/product/cam-mipiov9281/
I've already tried both camera drivers. I've tried with and without the dt-blob.bin. The cameras respond to i2cdetect -y 0 , so I at least think that the i2c lines are correctly connected, but they don't show up under /dev/video* Thanks!
[Edit] By enabling i2c0, one camera works, but only when using the ov9281 dtoverlay that's built into Linux 5.4 and the camera2 port.
