海思3559自定义时序直接输出hdmi给fpga没有输出

只接了数据线和时钟，没接i2c，差分1.8v到3.3v接入fpga，现在配置了自定义时序和强制输出，但是无时钟输出，看了相关打印，这个sink显示是未连接的。
stSinkCap.bConnected 0
stSinkCap.bIsRealEDID 1
stSinkCap.bIsSinkPowerOn 0
stHdmiAttr_get.bEnableHdmi 1
stHdmiAttr_get.bEnableVideo 1
stHdmiAttr_get.bEnableAviInfoFrame 1
stHdmiAttr_get.bEnableAudInfoFrame 1
stHdmiAttr_get.bAuthMode 1
现在无时钟信号输出。
拿了一块测试板，hdmi直出，连上hdmi线到显示屏幕有时钟，去掉显示屏也无时钟信号。
将hdmi的edid相关的线断掉也是相同现象，第一次做这个，请教一下大家。
