AIO-3399J开发HDMI-IN功能无法使能

Chip Platform Rockchip
1

固件类型：自行编译的固件
SDK包名称：rk3399/rk3399_linux_release_20220525_v2.5.1b
SDK修改内容：按照教程《https://wiki.t-firefly.com/zh_CN/AIO-3399J/linux_compile_gpt.html》中下载和同步代码，执行build.sh aio-3399j-ubuntu.mk之前，将kernel的代码检出到30e174dc173fba89c9b84a2651ad46cbc68bb0ac版本，确保HDMI-IN功能的实现代码有效，同时修改了aio-rk3399j-ubuntu.mk文件中的RK_KERNEL_DTS变量的值:
export RK_KERNEL_DTS=rk3399-firefly-aio
Log日志：aio-3399.log

系统启动时HDMI-IN芯片驱动相关的信息

系统启动后，系统中video类的设备文件

下面是系统启动的hdmi采集脚本，目前无法正确获取到device_id：

firefly@firefly:~$ cat /usr/local/bin/test_hdmirx.sh
#!/bin/bash

device_id=$(v4l2-ctl --list-devices | grep -A1 hdmirx | grep -v hdmirx | awk -F ' ' '{print $NF}')

v4l2-ctl -d $device_id --set-dv-bt-timings query

width=$(v4l2-ctl -d $device_id --get-dv-timings | grep "Active width" |awk -F ' ' '{print $NF}')
heigh=$(v4l2-ctl -d $device_id --get-dv-timings | grep "Active heigh" |awk -F ' ' '{print $NF}')

trap 'onCtrlC' INT
function onCtrlC () {
        echo 'Ctrl+C is captured'
        killall gst-launch-1.0
        exit 0
}

export XDG_RUNTIME_DIR=/run/user/1000
gst-launch-1.0 alsasrc device=hw:2,0 ! audioconvert ! audioresample ! queue !  alsasink device="hw:1,0" &
gst-launch-1.0 v4l2src device=$device_id ! queue ! video/x-raw,format=RGB ! capssetter replace = true caps="video/x-raw,format=BGR,width=$width,height=$heigh" ! glimagesink &

echo "[Ctrl + C] exit"
while true
do
        sleep 10
done
