断电后，如下图所示将GC2053的MIPI摄像头连接到开发板上。注意一定需要断电后才能连接，否则会将摄像头烧坏。 使用camerademo测试MIPI摄像头驱动[color=var(--ifm-link-color)]获取camerademo的帮助，用户可以根据自己的需求选择对应参数 [color=var(--prism-color)]root@TinaLinux:/# camerademo -h

[CAMERA] This program is a test camera.
[CAMERA] It will query the sensor to support the resolution, output format and test frame rate.
[CAMERA] At the same time you can modify the data to save the path and get the number of photos.
[CAMERA] When the last parameter is debug, the output will be more detailed information
[CAMERA] There are eight ways to run:
[CAMERA] 1.camerademo --- use the default parameters.
[CAMERA] 2.camerademo debug --- use the default parameters and output debug information.
[CAMERA] 3.camerademo setting --- can choose the resolution and data format.
[CAMERA] 4.camerademo setting debug --- setting and output debug information.
