Please provide the following info (check/uncheck the boxes after creating this topic):
Software Version

Hardware Platform
NVIDIA DRIVE™ AGX Xavier DevKit (E3550)

Our new carrier board use the HDMIDP0-TXDP0 , not use the HDMIDP2-TXDP2
1646659073(1)

so I change the device -tree file
hardware/nvidia/platform/t19x/galen/kernel-dts/common/tegra194-p2822-disp.dtsi
like this:

&head0 {

status = "okay";

nvidia,fb-bpp = <32>;

nvidia,fbmem-size = <265420800>; /* 8K (7680*4320) 32bpp double buffered */

nvidia,fb-flags = <TEGRA_FB_FLIP_ON_PROBE>;

win-mask = <0x3>;

nvidia,fb-win = <0>;

nvidia,dc-connector = <&sor0>;

nvidia,dc-flags = <TEGRA_DC_FLAG_ENABLED>;

avdd_hdmi-supply = <&p2888_spmic_sd0>; /* 1v0 */

avdd_hdmi_pll-supply = <&p2888_spmic_sd1>; /* 1v8 */

vdd_hdmi_5v0-supply = <&p2822_vdd_hdmi_5v0>; /* 5v0 */

};

&sor0 {

status = "okay";

nvidia,active-panel = <&sor0_hdmi_display>;

};

&sor0_hdmi_display {

status = "okay";

disp-default-out {

    nvidia,out-flags = <TEGRA_DC_OUT_HOTPLUG_LOW>;

};

};

&dpaux0 {

status = "okay";

};

&dpaux1 {

status = "okay";

};

&dpaux2 {

status = "okay";

};

&tegra_cec {

status = "okay";

};

and then the log like this

Hi, @feiyum

Are you working on DRIVE or Jetson platform? If it’s for Jetson, please create your topic in the corresponding sub-category under Jetson & Embedded Systems - NVIDIA Developer Forums. Thanks.

OK,thank you
