固件版本是EMMC：VIM3_Ubuntu-server-focal_Linux-4.9_arm64_EMMC_V0.9-20200530，文档中GPIO访问方法、WiringPi和RPi.GPIO均无法找到。论坛中帖子 给出的访问方法可以实现对37口的读写,相关配置的读取和帖子中的也是一样的，但是编程不方便，固件已经刷过几次了，均找不到，请问是没有集成进去还是需要另行安装？
The firmware I use is EMMC: VIM3_Ubuntu-server-focal_Linux-4.9_arm64_EMMC_V0.9-20200530. It is said WiringPi and RPi.GPIO has been moved to VIM3, but I cannot find them. I have seen the topic and achieved reading and writing on pin 37. But it is not convenient to program with python or C++. The file I cat is the same as the topic. I have reboot more than one time. There is someone who can help me?

@gpxin 20.04 没有集成进固件里,你需要去我们的github自己clone到板子上.按照readme运行.
