Jetson orin NX 16g with only one nvme partition，After flashing the real-time kernel, the effect is very poor

Robotics & Edge Computing Jetson Systems Jetson Orin NX

I have successfully flashed the real-time kernel using the method of compiling the kernel according to the official website manual.
And also attempted to use OTA methods, that is,

sudo apt install nvidia-l4t-rt-kernel nvidia-l4t-rt-kernel-headers nvidia-l4t-rt-kernel-oot-modules nvidia-l4t-display-rt-kernel

I have tried both methods and the final result is consistent:

uname-r

It’s all displayed

xxxx-rt-xxx

But I am using the Jetson Orin NX 16g version

sudo apt install rt-tests

Installed testing tools and used

sudo cyclictest -t 8 -D 1h --policy=fifo

Command, conduct testing.

From the test results, it can be seen that the real-time kernel is different from the regular kernel (or primary kernel?)? ）The effect is exactly the same.
Does it not reflect real-time performance? What settings should I make?

note:
My Jetson seems to be started by UEFI, which is all the background of the problem I encountered. I have no idea where to start.

There is no update from you for a period, assuming this is not an issue anymore.
Hence, we are closing this topic. If need further support, please open a new one.

hello 1559003615,

what did you meant the effect is very poor? did you have any logs for reference?
may I also confirm which Jetpack public release version you’re working with.
