is there a way to configure dual cameras on orin-nx using jetpack 6.2.1, either 2 lane or 4 lane. I have tried everything and I can only get CAM1 working with imx219
Is dual camera possible at all, if so, what is the procedure.
hello dakejahl,
since you’re testing with v4l2 IOCTL, besides to apply a patch to revert faulty DT settings, you’ll also need to revise mode definition for loading 4-lane configure.
for instance,
$public_sources/kernel/nvidia-oot/drivers/media/i2c/imx477_mode_tbls.h
static const struct camera_common_frmfmt imx477_frmfmt[] = {
{{3840, 2160}, imx477_30_fr, 1, 0, IMX477_MODE_3840x2160_30FPS_4LANE},
{{1920, 1080}, imx477_60_fr, 1, 0, IMX477_MODE_1920x1080_60FPS_4LANE},
please also add some debug prints within sensor driver side to check it’s loading correct mode settings.
hello rapidproto,
that’s strange, we’ve tested dual IMX219 on Orin Nano, it worked normally.
please have another new discussion thread if you need further supports.
I made the changes as you suggested, and now I see an error when the driver loads. Can you please provide the patch? I have no experience with this code and it would be much easier if you could provide the patch and I can apply/build/test and report back.

hello dakejahl,
just an FYI,
I’ve digging into this.
you should ignore previous comment #29 for loading 4-lane configure.
imx477_set_mode() should parse 2-lane or 4-lane settings correctly to write the mode table.
the root cause looks like IMX477’s 4-lane configure it’s not outputting camera frames completely.
if that’s possible, please rollback to JP-5 to confirm IMX477’s 4-lane settings.
hello dakejahl,
we’ve some internal investigation by checking schematic file of Raspberry PI HQ (IMX477).
it turns out IMX477 only has 2-lanes which seems standard for all their cameras based on their camera cable and connector design. according to the schematics, 4-lanes will never work.
that’s a mistake for adding IMX477’s 4-lane settings for Raspberry PI HQ. we’re having code review progress to remove that.
@JerryChang please see the first message in this thread. We are not using the raspberry pi cam…
Is there an off-the-shelf 4-lane camera that is KNOWN to work on the Jetson Orin Nano?
add @xingxing for sharing some info regrading to 4-lane camera on Orin Nano (J21,CAM1,CSI-C/D)
Yes. We verified CSI0-C/D can work at 4lane mode. Leopard imx477 can work at 4lane mode. But I’m not sure if we have the driver. You can contact support@leopardimaging.com to check.
Thanks
Xingxing
Which version of Jetpack are you using? Are you using the NVIDIA Dev Kit Carrier? Are you using a custom device tree overlay and oot kernel module?
Yes. using NVIDIA Dev Kit. The SDK is 36.4.3 and custom device tree overlay.
