Jetson Xavier NX RasPi V2 Camera not working at 120fps

Hi,

I am using the RasPi V2 Camera (Sony IMX219) with the Jetson Xavier NX.
I think this should work at 120fps at resolution 1280X720.
However, the maximum fps I can see is 60fps.

v4l2-ctl --list-formats-ext
ioctl: VIDIOC_ENUM_FMT
Index : 0
Type : Video Capture
Pixel Format: ‘RG10’
Name : 10-bit Bayer RGRG/GBGB
Size: Discrete 3264x2464
Interval: Discrete 0.048s (21.000 fps)
Size: Discrete 3264x1848
Interval: Discrete 0.036s (28.000 fps)
Size: Discrete 1920x1080
Interval: Discrete 0.033s (30.000 fps)
Size: Discrete 1640x1232
Interval: Discrete 0.033s (30.000 fps)
Size: Discrete 1280x720
Interval: Discrete 0.017s (60.000 fps)
Size: Discrete 1280x720
Interval: Discrete 0.017s (60.000 fps)

I am running the Jetson Xavier NX on the 15 Watt 6 Core mode.
Am I doing something wrong here or missing out on something?

hello ritvik.ranadive,

please check the kernel source for the IMX219’s mode table,
it’s indeed report 1280x720@60-fps.
for example,
$L4T_Sources/r32.5/Linux_for_Tegra/source/public/kernel/nvidia/drivers/media/i2c/imx219_mode_tbls.h

static const struct camera_common_frmfmt imx219_frmfmt[] = {
...

        {{1280, 720},   imx219_60fps, 1, 0, IMX219_MODE_1280x720_60FPS},
};

Hi @JerryChang

Sorry for the late reply, I was not at work for a while there.
Thanks for the info.
