Accessing the Terminal through in your Aetina Jetson Unit, e.g. pressing keys Ctrl + Alt + T, you can issue the command as soon as you start your unit, after finishing the booting process:

$ sudo dmesg | grep dts

The DTS file name with 'Aetina' at the end indicates that the Patch is loaded on the unit. To verify which JetPack version the Patch is for, like NVIDIA's version R35.4.1, check the NVIDIA JetPack Archive
