Hi nvidia
我们定制主板用的是Jetson AGX orin 8G模块
Linux 版本： Linux tegra-ubuntu 5.15.148-rt-tegra #4 SMP PREEMPT_RT Wed Mar 5 10:19:52 CST 2025 aarch64 aarch64 aarch64 GNU/Linux
基线：# R36 (release), REVISION: 4.0, GCID: 37537400, BOARD: generic, EABI: aarch64, DATE: Fri Sep 13 04:36:44 UTC 2024
打算通过PTN3460 把HDMI_DP2_TX0_N、HDMI_DP2_TX1_N 输出的2lane 信号转成lvds.
在加载Linux_for_Tegra/source/kernel/kernel-jammy-src/drivers/gpu/drm/bridge/nxp-ptn3460.c时老是报错，
从ret = drm_of_find_panel_or_bridge(dev->of_node, 0, 0, &panel, NULL); 函数中错误返回。

dts 配置如下：
i2c@3180000 {
status = “okay”;
+

  •                   lvds-bridge@40{

  •                           compatible = "nxp,ptn3460";

  •                           reg = <0x40>;

  •                           edid-emulation = <5>;

  •                           status = "okay";

  •                   };
          };

从./devicetree/bindings/display/bridge/ptn3460.txt中得知需要配置remote-endpoint = <&panel_in>;
在dts 目录中没有找到相关dsi 和panel 相关配置。
只见dtb_tool 和一个hex 文档。

请问我需要如何找到DP panel 调通DP转LVDS ?

Hi,

We don’t support panel on Orin but only common DP or HDMI monitors.

HI @WayneWWW
现在我们载板上设计了用PTN3460 来把DP 转成LVDS 信号，
Jetson AGX orin 的dts 配置中无法配置panel .
请问接下来需要如何进行？
是在PTN3460调试固件以兼容Jetson 的DP 输出 ？
还是改板换硬件方案？
或者有其它什么方式可以把DP转LVDS 用起来？

We don’t have experience with DP to LVDS, maybe other users could share their experience.
