最新发布的树莓派4B在烧录了官方系统buster以后，如果直接使用gpio readall去查看GPIO会出现错误。无法识别的情况，需要根据以下步骤进行wiringPi的更新：

登陆后打开一个终端输入：

cd /tmp6 Q1 V1 p8 g8 N+ Y* B0 g% x
wget https://project-downloads.drogon.net/wiringpi-latest.deb- e7 C. E. A8 N8 d+ h. F
sudo dpkg -i wiringpi-latest.deb

复制代码

然后再使用

gpio -v

复制代码

检查版本信息，确保版本为：2.52即可。

然后再执行：gpio readall
