你好

      我们使用j721s2, 8.4版本的sdk，在我们的板子上使用edp输出，运行/opt/vision_apps/vision_apps_init.sh后显示如下的错误

[MCU2_0]    394.295094 s: src/drv/dctrl/dss_dctrlApi.c @ Line 1176:
[MCU2_0]    394.295128 s: Set VP parameters IOCTL failed
[MCU2_0]    394.295177 s: DSS: ERROR: Dctrl default init failed !!!

1、请问这是什么原因造成的？

    1、我们用的是我们自己的板子，在插入显示器的时候，HPD是高电平，这个是测量过的，但是还是不知道为什么检测不到display。

    通过排查，发现是read DPCD失败，但是为什么会这样呢？我们使用的是edp 转hdmi的转换器

    Hi Shine

    英文论坛已经收到回复了，但是我没有账号直接在英文论坛中进行回复，所以还是麻烦转发一下，谢谢

    很开心收到回复

    1、我们tda4ve evm板子好像没有edp接口，只有两个DP输出接口，TDA4VL EVM有edp口吗？使用的是dp0还是dp1呢？是2lane还是4lane?

    2、我们的edp转hdmi转换器是第一次使用，在我们的板子上，我们使用的是dp0 2lane，请问dp0 2lane在硬件和软件上是否支持？

    3、我们现在的问题是读取dpcd 寄存器的值都是0，这个是什么愿意呢？

    Hi Shine

    谢谢回复

    1、我在evm板子上验证，我已经把延迟设置为5s，但是没有任何变化，从log上来看似乎没有识别到显示器

           "DSS: Display is not connected"

    2、能看一下你的vision_apps的log吗？以及你是使用哪种edp -> hdmi的转换器，希望能看一下你们的连接图

    期待回复

    Hi Shine

    谢谢回复

    1、我用的也是主动式的edp转hdmi转换器（activity edp ->hdmi adapter)，我在evm板上做过验证，dp -> dp的线是可以用的，dp -> hdmi（activity  adapter) 的转换器没有输出

    请看下面工程师的回复。

    Please find attached log from the EVM, with DP -> HDMI adapter enabled.
    0027.teraterm.log

    I also used now SDK8.4 release, and can see it working.. Is there a way to confirm that it is active DP to HDMI convertor?
