Imx219 camera error with tx2 nx dev kit

Hi,

I’m trying to connect a Raspberry Pi Camera v2.1 to a Waveshare TX2 NX developer kit. I’m getting i2c errors though and the camera isn’t available. This is similar or the same as this issue which had no resolution: I2c issues tx2 nx

Do I need to change the device tree or make some other change to get the camera working?

hello james-ld,

is this identical with TX2 NX DevKit?
can you running Jetson-IO utility to configure the CSI connector to enable IMX219?

4

I believe it uses a custom board so it’s not identical. When I run the jetson-io tool, it gives me a No DTB found for lanai-3636 fatal error and exits.

One other strange thing is that I tried this camera on an Orin Nano dev kit (official) and I see the same dmesg errors but the camera works fine there.

hello james-ld,

please check whether you’ve IMX219 dtbo in the root file system.
it should be located at… /boot/ you may try… $ sudo find / -name "*-camera-imx219-dual.dtbo" for confirmation.
as you can see in the Device Tree Overlays section, it’s compatible property to define the supported platform.
please update this accordingly since you’re now using other board configuration.
