TI中文支持网调试947遇到无法点亮Deserializer端lvds问题。lvds 24位 1920*720 SPWG mapping，Twisted Pair.
调试发现0x0c寄存器值总为4，怀疑可能是fpdlink没连接成功的原因，请问可能是哪里的问题？cable和Deserializer端设备在其他机器上验证过是正常的。
0x0c寄存器 bit0 LINK detect status可以用了判断连接吧？开机后缺省是Twisted Pair，如不配置任何寄存器，应该也能反应Deserializer端的连接状态吧？
以下是当前主要寄存器值：

Kailyn Chen：
如果是FPD link没连接成功的话，建议是先做个BIST测试，看是否pass。
