dm385 hdmi 无输出

Ti的专家们好,我用dm385+ar0331 ipnc3.5,设备拿到后用hdmi转vga接头接显示器,显示器上没有图像显示,转接头测试过没有问题,我想问是转接头不支持1080p的分辨率还是hdmi本身就没有输出?我按照hdmiuserguide上的操作cat  /sys/devices/platform/vpss/display0/edid  输出:

I2C No Ack

VPSS_DCTRL:  Failed to get EDID info 请问这是哪里的问题?

回复 Chris Meng:

恩,我已经验证过了,hdmi显示器上确实可以,可能是显示器或者转接头不支持这么高的分辨率,谢谢你@Chris Meng 回答了我很多的问题。

你好!我也遇到与你同样的问题,请问你是怎样解决的哇,我板子上是Micro-HDMI,我买了一个Micro-HDMI转VGA的转接头,然后输出到显示器,可是显示器没有反应。相关打印信息如下,谢谢!
