ubuntu固件。显示器无显示,已排除显示器和线的原因。
插拔HDMI线,信息如下:
[ 724.875883] dwhdmi-rockchip ff940000.hdmi: failed to get edid
[ 725.016804] dwhdmi-rockchip ff940000.hdmi: failed to get edid
[ 725.105777] rockchip-vop ff900000.vop: [drm:vop_crtc_enable] Update mode to 1280x720p0, type: 11
[ 725.116382] dwhdmi-rockchip ff940000.hdmi: PHY failed to power down
[ 734.130406] dwhdmi-rockchip ff940000.hdmi: PHY failed to power down
问题的原因是什么,怎么确定是否是硬件问题? |
