亲，目前两个相机都能拍照了，但是sudo reboot，重启后，又都不能拍照了了，需要重新./find_entity.sh，./media_setting_rpi5.sh XXX。

@veye_xumm
好像可以了，给您添麻烦了

MJYC

@veye_xumm
./media_setting_rpi5.sh mvcam -fmt RAW8 -w 1024 -h 1280

您好
1、./media_setting_rpi5.sh文件我没有更改
@veye_xumm
#!/bin/bash

I2CBUS_CAM1=4
I2CBUS_CAM0=6

#default params of YUV_type cameras
WIDTH_YUV=1920
HEIGHT_YUV=1080
MEDIA_FMT_YUV=UYVY8_1X16
PIXEL_FMT_YUV=UYVY

#default params of MV_type cameras
WIDTH_MV=1280
HEIGHT_MV=1024
MEDIA_FMT_MV=Y8_1X8
PIXEL_FMT_MV=GREY
2、执行./find_entity.sh
HZCU@raspberrypi:~/Desktop/raspberrypi_v4l2/rpi5_scripts $ ./find_entity.sh
Found mvcam @ i2c-4 entity on /dev/media2
Plese get frame from /dev/video0 and use /dev/v4l-subdev2 for camera setting.
3、执行完./media_setting_rpi5.sh，
HZCU@raspberrypi:~/Desktop/raspberrypi_v4l2/rpi5_scripts $ ./media_setting_rpi5.sh
This is a Raspberry Pi 5.
Usage: ./media_setting_rpi5.sh veyecam2m/csimx307/cssc132/mvcam -fmt [UYVY/RAW8/RAW10/RAW12] -w [width] -h [height]
This shell script is designed to detect the connection of a camera on Raspberry Pi 5.
It utilizes media-ctl and v4l2-ctl commands to configure the linking relationships and data formats of the media pad.
Once completed, you can directly use /dev/video0 or /dev/video8 to obtain image data.
4、media-ctl -p -d /dev/media2
HZCU@raspberrypi:~/Desktop/raspberrypi_v4l2/rpi5_scripts $ media-ctl -p -d /dev/media2

@veye_xumm
好的好的，感谢您的建议

MJYC

@veye_xumm

我觉得如果代码中，最开始能清楚所有占用设备的进程，然后开始拍照，这样不管是断电还是提前结束，都不影响下次代码运行。（我运行代码的时候，发现没有结束进程（比如没拍够，或者断电了）下次再拍，会报failed:Device or resource busy。

MJYC

@veye_xumm
我下午有空的，可否帮忙解决一下这个困扰我两周的问题吗

MJYC

@veye_xumm 可以可以提供一下解决方案，实现自启动，4个相机硬件触发同步拍摄。真的很急，我的微信号YMJXIAOBAI
