PREEMPT-RT Jetson nano fail

[fnoefen]

Hi,
I have been attempting to apply the PREEMPT-RT patch to my Jetson nano by following the steps layed out by ajcalderont here: PREEMPT-RT patches for Jetson Nano - #10 by ajcalderont
Unfortunately however i can not make work.
initially it boots up fine, and i can choose language, keyboard etc. But after that it keeps getting stuck on:
[ OK ] Starting update UTMP System Runlevel Changes.

a few steps before that something failes:
[FAILED] Failed to start nvpmodel service.

Dose anyone have an idear of what i am doing wrong?

Hi @trueshadow97, this is the guide updated for JetPack 4.5 (L4T 32.5): Real-time Linux for Jetson Nano (L4T 32.5) Install required packages sudo apt-get update sudo apt-get install libncurses5-dev sudo apt-get install build-essential sudo apt-get install bc sudo apt-get install lbzip2 sudo apt-get install qemu-user-static sudo apt-get install python Create folder mkdir $HOME/jetson_nano cd $HOME/jetson_nano Download required files L4T Jetson Driver Package: wget https://developer.nvidia…

and jetpack 4.5

Sorry for the late response, have you managed to get issue resolved or still need the support? Thanks

No worries, I no longer need support. As mentioned in my previous comment I made it work with a different guide and a newer version of jetpack
