Xavier, use HDMI ,sometimes he screen blinks and you can't log in

Hi,
We use jetpack4.4 filesystem, have removed the TypeC conversion chip from the board and used A USB-A port. We have found A problem:
After a few restarts, the screen blinks and you can’t log in,but it can be networked into the system,the log of " journalctl -xe" execution is as follows

Could you please give me some advice on how to solve this problem? Thank you!

BR,

Xavier kept flashing in this interface, and could not enter the login interface:

Looks like nvgpu driver is crashed. Could you check the dmesg when error happens?

Hi WayneWWW,

Thanks very much for your replay!

While this was happening, dmesg kept printing the following:

Hi,

How to trigger this error?
Do you have any application running when this error happens? Or just put the desktop idle would hit this problem?

Also, is there any customization in driver side?

Hi WayneWWW,

Sorry for the late reply!
In fact, we don’t know how it happens, right.
No applications are running; it happens during the power-up process, without waiting for.

In driver side ,we modified Camera and patched the real-time operating system patchs.
In our client board, the Type-C interface is removed, USB-A interface is used, and PD chip is removed.

And we tried to remove SOR, but it didn’t work:

-&sor0 {
-       nvidia,typec-port = /bits/ 8 <0>;
-};
-
-&sor1 {
-       nvidia,typec-port = /bits/ 8 <1>;
-};
-

Thanks,
BR,

Could you share the result of “lsmod”?

Yes,I‘m glad to do that.
When it happens, the lsmod is as follows:

Last login: Mon Apr 19 11:13:23 2021 from 192.168.10.227

Normally there will be “nvgpu” modules.

Thanks,

Hi,

You don’t need to post syslog and xorg.log at same time. Syslog contains the xorg.log inside it too. No need to mention you already parsed them.

What log would be printed if you modprobe nvgpu when error happens?

Hi WayneWWW,

OK.

The systemctl status nvpmodel.service log:

nvidia@xavier-rt:/var/log$ sudo systemctl status nvpmodel.service 
[sudo] password for nvidia:

When I execute the SS command, dmesg displays:

And does lsmod have nvgpu inside the list now?

nvidia@xavier-rt:/var/log$ lsmod
Module                  Size  Used by
nvgpu                1735188  0

nvidia@xavier-rt:/var/log$

What will happen if you restart gdm3 now?

How to do that? use "sudo service gdm restart”?

When I execute that command,the desktop is working.

Is this nvgpu driver build by yourself or it is directly pre-built binary from jetpack?

By myself.
