RP4 cnt > 4 error

[xk42]

I think I might have bricked it. I used make I2C_MODE=LINUX as RPI was throwing errors. Any ideas?

Has the sensor worked previously, and where did you buy it from?

I experience the same issue and on a RPi0 the camera and code works. Did you solve it somehow? One thing could be the cpu clock which gets changed on demand, but I already fixed that but it still occurs.

I am finding the same issue when my fps is set too high
