排查效果不佳问题的步骤

复现步骤：
在Debian下使用命令 gst-launch-1.0 v4l2src device=/dev/video22 ! video/x-raw,format=NV12,width=640,height=480, framerate=30/1 ! waylandsink 打开后摄的 mainpath，效果偏绿，光线较暗

排查过程：

查看3a是否是否运行
camera出流时候cat /proc/rkisp* 确认isp图像模块有在工作；
3a没有工作时

如没有3a模块开启，需开启rkaiq_3A_server
在终端下查看ps -ef是否有rkaiq_3A_server 进程，一般的在Debian下/etc/init.d目录下会有rkaiq_3A.sh的脚本在开机时启动rkaiq_3A_server ,在buildroot下也会有类似的脚本camera_rkaiq_test.sh


#!/bin/bash
### BEGIN INIT INFO
# Provides:          rkaiq_3a
# Required-Start:
# Required-Stop:
# Default-Start:
# Default-Stop:
# Short-Description:
# Description:       Setup rkaiq 3a daemon
### END INIT INFO

start_3A()
{
    /usr/bin/rkaiq_3A_server 2>&1 | logger -t rkaiq &
}

stop_3A()
{
    killall rkaiq_3A_server || true
}


case "$1" in
  start)
    start_3A
    ;;
  stop)
    stop_3A
    ;;
  reload)
    stop_3A
    start_3A
    ;;
  *)
    echo "Usage: $0 {start|stop}"
    exit 1
    ;;
esac
exit 0

如没有开启可手动启动，并查看kernel log或查看/var/log/syslog,如果没有开启，可能是rkaiq_3A_server在开启过程中出现段错误，可参考rk3588 rkaiq_3A_server 无法解析json文件记录
段错误有可能有几个原因：
1.rkaiq_3A_server编译有问题或版本有问题
运行strings ./usr/lib/librkaiq.so |grep "AIQ v"可以查看

2.效果参数json文件命名问题导致解析不到对应的json文件，需要和dts中的名词对应
3.json文件版本问题
查看356x是否有调试过类似的sensor，对应的是isp21
3588对应的是isp3x，如果是将json里面scene_isp21 改为scene_isp30，然后用isp2x_tuner选择3588配置以及对于rkaiq版本，导入修改scens的json重新生成试试
