Arducam IMX219. imx219_board_setup: error during i2c read probe (-121)

I have an Arducam IMX219 camera. And this camera behaves a little strange. When I turn off my Jetson Nano from current completely, for example, for 10 minutes, and then switch on, dmesg tell me that:

[    1.337516] imx219 7-0010: tegracam sensor driver:imx219_v2.0.6
[    1.360804] tegra-vii2c 546c0000.i2c: no acknowledge from address 0x10

[    1.384943] imx219: probe of 8-0010 failed with error -121

After this I switch off current and then swith on current of Jetson Nano with delay for 5 seconds, then this camera works fine. I tried to change camera and connector cable, but nothing changes. I cannot realize how to fix this issue. Do you have any suggestions?

hello charlz_klug,

I’m not sure what’s this, did you have your customize power-supply?
or… may I have more details.

After I turn off the board’s power and turn it on again, the camera starts working normally.

@JerryChang

did you have your customize power-supply?

Yes, we have our own custom board.

But I think, that our power-supply does not matter. We have an another type of camera “Rev.A” (see picture), and this camera works fine.

hello charlz_klug,

it should be device registration issues.
please share the complete kernel logs (i.e. $ dmesg > klogs.txt) of pass/failure scenario for comparison.

The problem was with some kind power issues in our custom motherboard. Our electronic engineers fixed this and the Arducam camera works fine.

Thank you!
