Hi bokyung86sky,
Yes, JetPack 4.3 - L4T 32.3.1 supports the PREEMPT-RT patches for the Jetson Nano board. Follow this instructions to compile and create the SD image:
What version of the Jetson Nano Kit do you have? It’s important to know that because you need to specify the correct revision with the -r option in the line:
sudo ./jetson-disk-image-creator.sh -o jetson_nano.img -s 14G -b jetson-nano -r 100
For example, for the latest Jetson Nano Kit, the correct revision is -r 300.
Best regards
