3588q 核心板接底板上,核心板接hdmi接口的摄像头报 hdmirx get_timing signal not ...
您好！问题描述如下：
1.使用3588q 核心板接rk的公板上，公板上的HDMI IN接口接相机,
核心板运行后,
串口不会出现下面的打印问题:
root@rk3588:/dev# [ 1496.773143] fdee0000.hdmirx-controller: hdmirx_wait_lock_and_get_timing signal not lock, tmds_clk_ratio:0

[ 1497.041679] rk_hdmirx fdee0000.hdmirx-controller: hdmirx_audio_interrupts_setup: 1
使用rk自带sdk里的v4l2-ctl工具可以获取到视频流;
2.把3588q 核心板接公司做的的底板上，底板上的HDMI IN接口接相机,
核心板运行后,
串口不断出现下面的打印:
root@rk3588:/dev# [ 1496.773143] fdee0000.hdmirx-controller: hdmirx_wait_lock_and_get_timing signal not lock, tmds_clk_ratio:0

[ 1497.041679] rk_hdmirx fdee0000.hdmirx-controller: hdmirx_audio_interrupts_setup: 1
参考 rk3588 sdk 里自带的HDMI-IN里Rockchip_Developer_Guide_HDMI_RX_CN.pdf
的8.4 HDMI IN信号不锁定问题
root@rk3588:/mnt# io -4 -l 0xc 0xfdee0594
fdee0594:00000000 00000000 00000000
HDMI插入时
console:/ # io -4 0xfdee0050
fdee0150: 00000001 // bit0：1表示HPD拉高，0表示HPD拉低
HDMI拔出时
root@rk3588:/mnt# io -4 0xfdee0050
fdee0050:00000000 // bit0：1表示HPD拉高，0表示HPD拉低
root@rk3588:/mnt#
说明HPD是配置好地,
v4l2-ctl -d /dev/video11 --query-dv-timings
查询也出现异常,如下:
root@rk3588:/mnt# v4l2-ctl -d /dev/video11 --query-dv-timings
fdee0000.hdmirx-controller: hdmirx_query_dv_timings sVIDIOC_QUERY_DV_TIMINGS: failed: No locks available

我也是同样的问题，同样的开发板，请问这个问题怎么解决呢？
