This MIPI driver is specific to only RPi OS and will not work on any ARM based Ubuntu OS. If you are running bullseye, enable the legacy camera support from raspi-config and add start_x=1 to /boot/config.txt. Then we are good to go. Possible errors libmmal_core.so.0 not found after running make clean && make. This library can be accessed only after enabling the legacy camera support as it depends on the library. https://koushikv.me/posts/fixing-green-tint-and-orientation/ Fri, 04 Feb 2022 00:00:00 +0000 https://koushikv.me/posts/fixing-green-tint-and-orientation/ Stereo cameras once connected to the hat, have to be calibrated before using it. There were a couple of issues that I encountered while calibrating. First one being the green tint on both sensors, IMX 219, and the second one being the incorrect orientation. However there was an error while running the calibration code, Error mmal: Failed to fix lens shading, use the default mode! but the code ran just fine.
