在ITX-3588J上硬件HDMI_RX端口连接笔记本,VGA接口连接屏幕。主板上执行/usr/local/bin/test_hdmirx.sh ,RX信号没有显示到屏幕上,屏幕仍然显示系统界面。执行后log如下: firefly@firefly:~/Desktop$ /usr/local/bin/test_hdmirx.sh Failed to open /dev/video0: No such device VIDIOC_QUERY_DV_TIMINGS: failed: Link has been severed VIDIOC_S_DV_TIMINGS: failed: Numerical result out of range [Ctrl + C] exit Setting pipeline to PAUSED ...
