Hi, I tried to use the sensor ov5693 to work on agx-xavier, but the default driver didn’t work, whether I need to modify something, or not.
hello wjv321,
ov5693 sensor is supported by default,
please also access L4T Sources via download center,
you may check below for ov5693 sensor driver and also sensor device tree for reference,
$l4t-r32.2/public_sources/kernel/nvidia/drivers/media/i2c/ov5693.c
$l4t-r32.2/public_sources/hardware/nvidia/platform/t19x/common/kernel-dts/t19x-common-modules/tegra194-camera-e3326-a00.dtsi
may I know is there any failure messages for reference?
suggest you should contact with your sensor vendor, or you might also check with Jetson Preferred Partners for further support.
thanks
Hi, JerryChang, thanks for you reply.I setted CONFIG_VIDEO_OV5693=m, and insmod ov5693.ko, ov5693_probe didn’t run.If I setted CONFIG_VIDEO_OV5693=y, and insmod it, it didn’t run either.
hello wjv321,
ov5693 sensor driver is by default built-in with the JetPack release image. it should detected by default.
we also used the plugin manager for device registration.
plugin manager read the onboard eeprom to loading the device tree, you might also disable that if your camera board did not have eeprom.
thanks
Hi, JerryChang, I tryed to modify tegra194-p2822-camera-modules.dtsi, change status = disable to status = okay. Kernel startup log printed error like this:

The camera module does not have eeprom.
hello wjv321,
you’ll need to Using the Main Platform Device Tree File for the camera board without eeprom.
were you working with 6-cam camera board?
please check below device tree for six ov5693 reference drivers.
please also contact with your sensor vendor for correct i2c configurations.
thanks
