DS90UB983-Q1: 983搭配984，使用984出pattern

Part Number: DS90UB983-Q1

使用983搭配984无法配置出图，验证984单独出pattern图片。但984也无法单独配置出pattern画面。请问这种edp的链路该如何配置984出pattern画面：

  屏              ->           984

eDP0_D0P -> eDP_D3P 
eDP0_D0N -> eDP_D3N
eDP0_D1P -> eDP_D2P
eDP0_D1N -> eDP_D2N
eDP0_D2P -> eDP_D1P
eDP0_D2N -> eDP_D1N
eDP0_D3P -> eDP_D0P
eDP0_D3N -> eDP_D0N

屏幕timing

THW[0] = 3120
TVW[0] = 1842
AHW[0] = 2880
AVW[0] = 1800
HBP[0] = 60
VBP[0] = 8
HSW[0] = 60
VSW[0] = 2
HFP[0] = 120
VFP[0] = 32
HSP[0] = 0
VSP[0] = 0
PCLK[0] = 344.82

    您好！

    可以使用98x 脚本生成工具 v5.5生成983-984 PATGEN 脚本。 这将帮助客户按照自己的意愿生成自己的脚本。 生成脚本后、客户可以使用这些寄存器重新映射 eDP kanes、如上所述：

    客户需要首先使用此寄存器启用重映射功能：

    你好，

    感谢您的回复！

    我们当前就是使用v5.5的脚本生成了寄存器的配置，但是依然无法让984显示pattern画面。您发的图片这个网页上是无法打开的，有无文字描述或其他方式给我们提供上面的图片信息呢。

    另外期望您看一下此问题的关联子问题，我们983输出信号后，984的54寄存器一直显示无有效frame，此问题还需要您的帮助，感谢！

    我可以为他们生成 patgen 脚本。 客户使用的 DP 率是多少？ FPD-Link 速率是多少？

    您好，如果使用984输出pattern的话，我理解是不需要关心FPD-Link 速率的，只需要关心问题前面的timing和线序，不是吗？

    您是对的。 让我们从984 PATGEN开始，看看屏幕是否可以显示出来。 我使用提供的解决方案生成了984 PATGEN脚本，我还根据您共享的内容添加了DP通道重新映射：

    客户能否对此进行测试，并告诉我他们能否显示显示屏。

    hello 感谢您的支持！

    从您提供的脚本内容看，并没有dp线序的重新映射。

    验证后，显示屏也未能显示pattern画面。

    另外补充一个信息，屏端的dp接收只支持2.7G的速率

    您好

    您可以尝试附加此脚本吗？ 我所做的就是将DPTX速率更改为2.7Gbps。

    Lane Remap脚本是我将其添加到以前的代码中，并且我也将其添加到该脚本中：

    如果运行脚本后屏幕没有显示增补数据，可以尝试执行软重置写入0x1以注册0x1。

x 出现错误。请重试或与管理员联系。
