@hmlow Glad it worked! For future reference, the imx214_flip driver should be available internally from SDK 1.1 (system image 1.7) onwards. Rather than downloading from the above links, after SDK 1.1 is released the procedure will be as follows:
rm /usr/lib/camera/com.qti.sensormodule.imx214_3.bin
cp /usr/share/modalai/chi-cdk/imx214-flip/com.qti.sensormodule.imx214_flip_3.bin /usr/lib/camera
