How did to configure dts file to fix this problem?

337247537,

Please refer to: https://elinux.org/Jetson_TX2/r28_Display_debug ->Issues X11 returns below error and cause failure (TX2).

Hi WayneWWW,
Thanks for you response. But I want to know hwo to edit dts file to enable DP0 and DP1.I reference this https://devtalk.nvidia.com/default/topic/1004141/?comment=5164427 to enable sor sor1 and nvdisplay15220000. I just find “DC OR NODE connected to /host1x/sor1” from system message and “tegradc 15210000.nvdisplay” message.But not find any sor or tegradc 15220000.nvdisplay meaasge.

I think DP1–>SOR1–>15210000.nvdisplay,DP0–>SOR–>15220000.display. is that correct ?

337247537,

Sounds that you have not yet enabled any of HDMI monitor.
Please refer to this dts file: tegra186-quill-p3310-1000-c03-00-dsi-hdmi-hdmi.dts .

You could check your runtime device tree on tegra by below node -> /proc/device-tree.

Hi,
I reference “https://elinux.org/Jetson_TX2/r28_Display_debug”. And Forcing edid to 1280x1024P.(read form monitor).

  1. Prepare a known 256byte EDID.
  2. set use_fallback = true; in tegra_edid_get_monspecs() under edid.c.
  3. fill in the known EDID to default_720p_edid[256].

But kernel load stop at this.

337247537,

What are you doing?

I didn’t ask you to force the edid but to follow the topic in that link with title “Issues” -> “Issues X11 returns below error and cause failure (TX2)”.
That is for your error “tegradc 15210000.nvdisplay: sanitize_flip_args: WIN 3 invalid size:w=0,h=0,out_w=0,out_h=0”

Hi,
Thanks. OK,I will restore to the previous state.And follow this topic.

Hi,
I restore the board to previous state. pull-none UART1_TX,UART0_RTS,UART7_TX,UART3_TX,UART3_RTS. But system log no diffenent.
