Build kernel using Jetpack and ov4689 driver

Building kernel sources

Follow the instructions in NVIDIA_Jetson_Nano - Building the Kernel from Source to build the kernel sources.

Enable driver

Once you are following the guide there is a step make menuconfig, which allows you to enable the ov4689 driver as built-in.

make ARCH=arm64 O=$KERNEL_OUT menuconfig

Select the driver. The menu option is located:

-> Device Drivers
  -> Multimedia support (MEDIA_SUPPORT [=y])
    -> NVIDIA overlay Encoders, decoders, sensors and other helper chips
       <*> OV4689 camera sensor support

Test your Kernel image using Jetpack root file system

Check the kernel version. At this moment you can test the image created in order to see the new kernel is working correctly. You have to see a new kernel version with the correct date of compilation:

uname -a 
Linux nvidia 4.9.140 #6 SMP PREEMPT Tue May 7 16:25:38 CST 2019 aarch64 aarch64 aarch64 GNU/Linux

You can see that the driver is probed, execute the line: dmesg | grep "ov4689"

Expected output:

nvidia@nvidia:~$ dmesg | grep "ov4689"
[    1.667200] ov4689 6-001a: detected ov4689 sensor

video devices created:

ls /dev/video*
/dev/video0
