Kernel generates the following messages all the time: fdee0000.hdmi_receiver: hdmirx_wait_signal_lock: signal not lock, tmds_clk_ratio:0 fdee0000.hdmi_receiver: hdmirx_wait_signal_lock: mu_st:0x2, scdc_st:0x0, dma_st10:0x10 "v4l2-ctrl --all" reports that HDMI In is detected, /dev/video[0-4] exist. I tried two signal sources: - AMD Radeon WX2100 (via passive DisplayPort -> HDMI adapter) - AMD Radeon RX6700XT (HDMI port) Same situation with both - kernel messages as above on RK3588 system, no connected monitor on host side. Usually I used MPlayer or MPV to check v4l2 devices but here it fails too: $ mpv av://v4l2:/dev/video3 [ffmpeg/demuxer] video4linux2,v4l2: Not a video capture device. [lavf] avformat_open_input() failed Failed to recognize file format. Exiting... (Errors when loading file) Checked SBC schematics again and HDMIIRX_DET_L line is GPIO1_D5 like it my patch. What I go wrong?
