Hi,

I designed a carrier board for the Xavier.
I have a problem on power-up and I see that the Xavier reboots itself every 5-6 seconds.
I can see the logo of NVIDIA on screen , but then it disappears,
You can see the attached file of the debug console.

Do you have any suggestions?

Thank you,

Efi

Hi,

Yes, your board cannot boot the kernel and watchdog triggers the reboot.

Few thing from your log

  1. I notice your board is not able to read module eeprom through i2c. This part should be necessary.

  1. Is this board always reboot at the same timing? For example, it is rebooting after below error. Does it ever change?

Hi Wayne,

Thank you for your response,

  1. I saw the EEPROM error but I don’t think it causes the problem. I tried to use a configuration file (DTSI) which is different than mine - it doesn’t have HDMI but I saw that the Xavier was up eventually after plugging and removing the HDMI cable. Although HDMI is not configured in the file I could see the screen.
    My configuration file has a few differences than the new one I used and up until now I couldn’t figure out what causes these reboots .
    Is there a GPIO or other signal which is critical and can cause this?

  2. Please see the attached file. I saw that sometimes it get stuck on the same line, but not always. in the attached file you can see multiple reboots.Reboot_3.txt (121.2 KB)

  3. I’m attaching the DTSI files.DTSI_1.zip (5.1 KB)

Any new suggestions?

Thank you,

I don’t know. Maybe you can share the boot up log based on this dtsil to us too. Also, share the diff file between your dtsi and this dtsi.
