Should I be concerned about these messages when booting


I recently got a Nano B 4 GB. After going through the initial setup, I upgraded to Ubuntu 20.04 (I know it is isn’t supported officially) so that I can run ros2.

I was playing around with trying to connect a camera and I decided I had an incompatible camera. So, I removed the camera and rebooted. However, I see this when the system is booting:

1.142381] tegradc tegradc.1: dpd enable lookup fail:-19

I just ordered a camera with an IMX219 sensor so I’m concerned that I’m seeing these messages when booting even when no camera is connected.

If I’m missing something obvious, thanks for taking it easy on me. I’m relatively new to linux.

hello user114566,

that’s due to Nano is parsing the imx219 camera sensors by default,
you may check device tree sources to disable that. or, please simply to ignore that messages.
