hello hydropericardi,

according to the logs, it’s system trying to register IMX219 camera device but has i2c communication failed.

had you validate this camera device before? please examine pin direction of your flex cable.

the camera is in working condition i have tested it before on jetson with another image .by pin direction if you mean to say blue coloured side of ribbon cable outward facing then i have done that the camera is still not working

may I know which sensor vendor it is? Jetson Nano support Raspberry pi imx219 by default.

it is raspberry pi imx219 -200 camera

may I also know what does this -200 represent? could you please share the webpage to the product?

hello hydropericardi,

we’ve test/confirmed Jetson Nano works with Raspberry pi imx219 on r32.7.4
please also share the L4T release version of your target. i.e.$ cat /etc/nv_tegra_release

furthermore, please also check waveshare IMX219 camera module around forum discussion thread.
for example, Topic 258404, Topic 239786, and Topic 212472.
