Problems in RT Kernel Installation

Continuing the discussion from Jetson AGX Orin - RT Linux without reflashing:

Hey I have been working on that the last weeks, and after building the RT kernel, I replaced the Linux_for_Tegra/rootfs/ with / of the Orin, and my orin is now in a inconsistent state. I connected it to display port, but only gives me black screen (i attempted fn12,8,2, etc). I don’t know how to solve that, and to really install RT Kernel. If i can have more help i will be so grateful

Did you build the display driver?

If its apart from kernel installation guide, no I didn’t build the display driver. I only tried to follow the guide steps.

Of course it’s in the guide:

I didn’t know that was necessary to build a display module to have GUI, i thought that was included. Now that i replaced the rootfs/ → / without display module, what can i do for solving that for having GUI or check that RT have been installed correctly?

You can still access the device with serial console to continue compilation.
Also, I don’t know how you come up with the idea of replacing the whole rootfs; it’s very dangerous.
Please don’t do it and install only the kernel image and other kernel modules.

You recommend me to replacing the whole rootfs, i deduced that was the correct way.

If you are compiling natively, just replace every Linux_for_Tegra/rootfs/ in the document with / on your device.

So how i should install only the kernel image and modules?

NO, I just mean whenever the document mentions Linux_for_Tegra/rootfs/, it means / on your Jetson.
I’m not telling you to replace the whole rootfs…

Replace /boot/Image to update the kernel. Put kernel modules into /lib/modules/($uname -r)/.

Okay thanks. Ill try again with this steps after repairing the Jetson to any stable state.
