Hi,
I have bought a raspberry pi hq cam and want to use it with the jetson nano dev kit.
I get these error messages:
[ 1.742614] imx477 7-001a: tegracam sensor driver:imx477_v2.0.6
[ 2.043048] imx477 7-001a: imx477_board_setup: error during i2c read probe (-121)

~$ dmesg | grep -i tegra-vii2c

[ 2.355954] tegra-vii2c 546c0000.i2c: no acknowledge from address 0x1a
So while searching for a solution I found this post:
“Raspberry Pi HQ camera with Jetson Nano”
which suggests to remove the R8 resistor since the hq cam needs 3.3V for for reset GPIO in the camera interface.
When I run the jetson-io configuration tool and select imx477 I see the following:
Here it says 3.3V.
I am not quite sure if removing the R8 is still needed. For me it at least does not work without removing but I am a little hesitant removing the resistor.
Anything else I need to consider when using HQ Cam with imx477 on the jetson nano dev kit using jetpack Version: 4.6.1-b110 before I try to remove the resistor?
