因为泰山派的摄像头驱动已经配置好了，只需要取消注释一下设备树的头文件即可，默认配置的是OV5695摄像头。买回来接上之后发现摄像头画面发绿，以下是调试步骤：

1.在网上搜了一下好像是ISP服务没启动，没有对画面进行处理，shell启动rkaiq_3A_reverce，但是启动失败，打印日志：

2.注意到这条错误E: /opt/iq_parser_v2/j2s/j2s_utils.c(129) [j2s_read_file]: failed to read: ‘/etc/iqfiles//’，经过搜索好像是没有iq配置文件，在SDK中取出配置好的iq文件：./external/camera_engine_rkaiq/iqfiles/isp21/ov5695_TongJu_CHT842-MD.json。将该文件移到开发板的/etc/iqfiles/目录下再次启动rkaiq_3A_reverce还是启动失败，打印日志相同。之后检查了设备树中i2c节点的camera-module-name = "TongJu"和camera-module-lens-name = "CHT842-MD"变量，与文件同名。表明不是这个文件的错误。

3.之后在泰山派的官方资料中发现原来有官方教程
在这里插入图片描述
经过尝试发现还是无法启动rkaiq_3A_reverce服务，但打印日志变化了：

4.在打印信息中注意到[14:49:44.546929][XCORE]:XCAM ERROR RkAiqCalibDbV2.cpp:322: access /etc/iqfil.json failed!
然后我把之前移到/etc/iqfiles/目录下的ov5695_TongJu_CHT842-MD.json文件重更名为了iqfil.json并移到/etc目录下，再次启动rkaiq_3A_reverce，启动成功，再次打开摄像头画面变为正常。
