Hi Team,
We are encountering an HDMI disconnection issue (black screen appears) after the boot process. We have observed the following data logs:

Actually I don’t see any error from the log you provided. Is this a custom board or NV devkit? or you are not sure about what does my question mean?

Hi,
This one is Jetson AGX Xavier Dev Kit

4

What is the monitor you are using there? The 85500K in the log indicates it seems a low resolution one.

5

Thanks for your immediate response.

Monitor Spec: LG - 19M38HB, 19 Inch (47cm) 1366 X 768 Pixels , Led HD Ready Monitor

Could you share the log of /var/log/Xorg.0.log?

Why are you repeating something that I didn’t ask for…?

On the Jetson Xavier AGX, the system boots and the HDMI display works when using either the eMMC or the SD card by setting the primary and secondary boot options in the /boot/extlinux.conf file (located on the SD card). However, when I remove the SD card and attempt to boot directly from eMMC, the HDMI display does not work and shows an above shared error in dmesg. I have shared the /var/log/Xorg.0.log when I remove SD card and try to boot directly from eMMC. Xorg.0.log (8.3 KB)
