Imx219_board_setup: error during i2c read probe (-121)

Hi - I just received my jetson nano 2gb a few days ago and I have not been able to establish a connection with a camera through the MIPI CSI-2 port. I’m using an HDMI to CSI-2 module and I’ve verified connectivity and operation with a Pi development board so the camera or the module itself I don’t think is the issue.

During boot up, these messages appear which I think are related to the camera device.

imx219 6-0010: imx219_board_setup: error during i2c read probe (-121)
imx219 6-0010: board setup failed
cp: not writing through dangling symlink 'etc/resolv.conf'

when I run ls /dev, video0 is not present.

I have installed v4l-utils and it still hasn’t solved the issue.

Here’s some of the output from dmesg

[    1.206213] imx219 6-0010: tegracam sensor driver:imx219_v2.0.6
[    1.229503] tegra-vii2c 546c0000.i2c: no acknowledge from address 0x10

[    4.214092] tegra_cec 70015000.tegra_cec: timeout in tegra_cec_native_write_l:172.

Any ideas on what could be causing this?

Thank you

Have you connect the imx219 sensor board? If not you need to update the device tree and driver for your “HDMI to CSI”

Thanks for your response. I don’t have an imx219 sensor board so there’s the problem. Ok. I’m new to this so not sure how to update the device tree and driver. It looks like this post HDMI 2 MIPI CSI Device Tree has some info. Is there documentation available that explains the process?

Thanks in advance!

Check below document and sensor programing guide.
