AHB/Hi3520d JTAG Enable/啟用

Greetings.

I am not a native chinese speaker, so I will be using google translate to speak for me.
If these translations are offensive, I apologize in advance.
If there is any question as to the meaning of what I say, the original post will be the
proper interpretation.

I had recently purchased a Hi3520D board on taobao, and carefully tracing the leads
from it, I found the JTAG pinout and by moving a resistor enabled it.

Has anyone investigated this before? I was able to get openocd to detect a debug tap,
will be working on a proper config file soon.

問候。

我不是一個中國母語，所以我會使用google翻譯為我說話。
如果這些翻譯是攻擊性的，我提前道歉。
如果對我所說的意思有任何疑問，原來的帖子將是
正確解釋。

我最近在淘寶上購買了一個Hi3520D板，並仔細跟踪線索
從它，我發現JTAG引腳分配和通過移動電阻啟用它。

以前有人調查過嗎？ 我能夠得到openocd來檢測調試水龍頭，
將很快工作在一個正確的配置文件。
