Raspberry Pi Camera Module 3 をraspberry pi zero 2で動かす方法

ケーブルを繋ぐ
raspi-configから、cameraの設定をONにする
3Interface Option>1Legacy Camera>ON>再起動する

vcgencmd get_camera
を打つと、
supported=0 detected=0, libcamera interfaces=0
となる

libcamera-jpeg -o test1.jpg　を打つと下記のエラーが出た。
```

対応策として、/boot/config.txt　ファイルを、下記で書き換えた　[出典元](https://github.com/geerlingguy/pi-camera/blob/master/config.txt)
