Build kernel using Jetpack and imx397 driver
Jetson Nano
Building kernel sources
Follow the instructions in NVIDIA_Jetson_Nano - Building the Kernel from Source to build the kernel sources for the Jetson Nano.
Enable driver
Once you are following the guide there is a step make menuconfig, which allows you to enable the imx397 driver as built-in.
make ARCH=arm64 O=$KERNEL_OUT menuconfig
Select the driver. The menu option is located:
-> Device Drivers
-> Multimedia support (MEDIA_SUPPORT [=y])
-> NVIDIA overlay Encoders, decoders, sensors, and other helper chips
<*> IMX397 camera sensor support
Test your Kernel image using Jetpack root file system
Check the kernel version. At this moment you can test the image created in order to see if the new kernel is working correctly. You have to see a new kernel version with the correct date of compilation:
Jetson Nano
uname -a Linux nvidia 4.9.140 #6 SMP PREEMPT Tue May 7 16:25:38 CST 2019 aarch64 aarch64 aarch64 GNU/Linux
Nano EVM kit
You can see that the driver is probed, execute the line: dmesg | grep "imx397"
Expected output:
nvidia@nvidia:~$ dmesg | grep "imx397" [ 1.667200] imx397 6-001a: Driver Version: 0.1.0
