請問一下now HDMI is deleted 是什麼意思?

預設Orin NX就沒有打開HDMI. 為何會需要delete HDMI?

---

May I clarify what does that mean “now HDMI is deleted”?

By default Orin NX does not have HDMI enabled. Why there is need to delete HDMI?

[wangqunpj]

On the Development Board, HDMI and DP is multiplexing， because our board is customized, so HDMI is deleted on our design. there are only DP interface.

Orin NX 預設的software就是DP enabled. 如果DP在你那邊沒起來的話, 請你們review hardware.
software這邊沒有什麼能更改的

另外我也不太確定你所謂的 “HDMI and DP are multiplexing”. 可以用線路圖指出你在說哪部份嗎？

Hi,
我们还是没有解决MINIDP的显示问题，
1）我们是定制的底板；
2）使用的是MINIDP连接器；
3）使用的是ORIN NX的DP1接口；
目前的情况是： HDMI显示器接入HDMI转MINIDP线后，MINIDP连接器可以量到HPD信号变高，但AUXp/n上量不到任何信号。
please help me ,ths

這個說真的沒有什麼辦法幫你 請你就把硬體做成跟Orin Nano devkit一樣

Orin部份的display軟體能設定的東西幾乎為0.

除非你根本就沒用Orin Nano預設的設定燒, 不然這個就只能純粹從hardware做修正.
