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:
Jetson TX1/TX2
uname -a Linux tegra-ubuntu 4.4.38 #21 SMP PREEMPT Thu May 9 14:30:09 CST 2019 aarch64 aarch64 aarch64 GNU/Linux
J100 TX2
You can see that the driver is probed, execute the line: dmesg | grep "(Tegra I2C adapter)"
Expected output:
