When Jetson TX2 normal works for hours can't display by HDMI

Yesterday I turn on a Jetson TX2 machine,let it normal work and display the graph by HDMI interface,but after hours working,the graph disappearance,times to plug and unplug HDMI can’t normal display.So I decide to reset the machine for watch HDMI display whether normal or not,the result is HDMI display normal working,this test exclude the hardware damage,and I check system log,found:

  • Parent Clock set for DC plld2 tegradc 15210000.nvdisplay: hdmi: pclk:148500K, set prod-setting:prod_c_150M tegradc 15210000.nvdisplay: unblank tegradc 15210000.nvdisplay: dc_poll_register 0x41: timeout tegradc 15210000.nvdisplay: dc timeout waiting for DC to stop tegradc 15210000.nvdisplay: dc_poll_register 0x41: timeout tegradc 15210000.nvdisplay: dc timeout waiting for DC to stop tegradc 15210000.nvdisplay: tegra_nvdisp_wait_for_common_channel_to_promote: DC 1 timed out waiting for COMMON promotion tegradc 15210000.nvdisplay: blank - powerdown tegradc 15210000.nvdisplay: sor_poll_register 0x15: timeout tegradc 15210000.nvdisplay: dc timeout waiting for OR MODE = SAFE tegradc 15210000.nvdisplay: sor_poll_register 0x16: timeout tegradc 15210000.nvdisplay: dc timeout waiting for HEAD MODE = SLEEP tegradc 15210000.nvdisplay: dc_poll_register 0x41: timeout tegradc 15210000.nvdisplay: dc timeout waiting for DC to stop tegradc 15210000.nvdisplay: dc_poll_register 0x41: timeout tegradc 15210000.nvdisplay: dc timeout waiting for DC to stop PD DISP2 index4 DOWN PD DISP1 index3 DOWN PD DISP0 index2 DOWN tegradc 15210000.nvdisplay: unblank PD DISP0 index2 UP PD DISP1 index3 UP PD DISP2 index4 UP

Hi,

The problem description sounds like a hardware issue. Are you using a nvidia devkit or custom carrier board?

Could you remove all unnecessary peripheral here, re-flash the board and then see if issue is still?

Also, you could try the same software setup on other tegra device (if you have any).

Thanks for your answer!
Maybe my description can’t express correct the issue,sorry
I used nvidia devkit 、had re—flash the board and remove unnecessary peripheral,just connect HDMI display 、network、USB mouse and USB keyboard,that working for hours,the display graph disappearance,and reset the machine,graph normal display,So it can exclude hardware issue。

Hi,

Then I guess maybe we need to reproduce this issue on our side too. Could you share how many hours you waited until this error happens? BTW, does reboot the device help?

Could you also try with other jetson TX2 module/devkit and see if this issue only happens to one module or not?

At that time, I tested a total of 10 same machines, only one of which had an abnormal HDMI display。
About 48 hours of operation, the graph disappearance。

I would suggest to RMA this module if only one got issue.

Hi
I retested it for more than 48 hours
So far,it hasn’t happened that graph disappearance connected with HDMI
