I’m going to elaborate more on this - so I have a Raspberry Pi HQ camera attached to my Jetson Nano Dev kit, I have installed RidgeRun IMX477 driver and edited the device tree so it would allow longer exposures (default is 683709 us) but I think that the problem is with framerate limits. The framerate is an integer value, meaning, that I can’t get it below 1 FPS.
Even though I can set the exposure time longer after I change device tree settings for IMX477 sensor, I’m limited by minimum framerate, which would mean that the max exposure time I can get is 1 second. Do you know how to edit the device tree so it would allow for decimal point framerate?
So the settings in device tree (with default values) that have something to do with framerate are:
framerate_factor = “1000000”;
exposure_factor = “1000000”;
min_framerate = “1000000”;
max_framerate = “30000000”;
step_framerate = “1”;
default_framerate = “30000000”;
min_exp_time = “13”;
max_exp_time = “683709”;
step_exp_time = “1”;
default_exp_time = “2495”;
So the main thing is to get the framerate to be with a decimal number, I think
