实操Linux之基于RP2040 micropython固件编译
本文章接续上篇文章，如果没有相应的环境，是无法部署了！
开篇正文：
需要学习和准备知识：
0、ubuntu 常用命令
1、ubuntu 系统包管理功能和命令
2、GIT版本控制的功能和命令
进入程序流程：
打开虚拟机软件，选择UBUNTU 26.04 服务器版本 虚拟机
1、系统启动后，分别输入 账号 、密码（密码输入时不显示）
2、登录成功后的状态如下：
3、切换到ROOT账户（ROOT权限涉及安全问题，请妥善使用）
    设置root账户密码
4、可选：编辑sshd_config文件 打开ssh登录权限（后期SSH客户端登录比较方便）不用可略过！默认端口为22，请自行修改端口，防止攻击
5、设置完毕后，重启电脑，用root账户登录系统
------------------------------------------------------------------------
包管理阶段：安装过程需要网络畅通和时间
1、更新系统到最新
2、更新版本后，删除过时的包
3、重启系统
4、安装所需依赖包：
5、克隆 micropyhthon 官方源代码
我在盘符根目录创建了一个RP2040目录，以后所有开源项目都放在此目录中，克隆micropython项目，增加了 --recursive 克隆主项目同时克隆包含的子项目代码，克隆时需要连接GITHUB官网站！大家可能会因为网络问题无法连接！请自行设置 github国内加速 完成此项操作！
6、克隆完成后，进入micropython目录
7、操作时请注意操作的所在目录和命令参数和字母大小写
编译成功的结果样式：
8、进入RP2040对应的项目目录
第一个固件版本出炉：再次执行make命令就可以编译出UF2包了

固件文件 firmware.uf2

我已保存文件名，并放入RP2040单片机中测试！
已测试成功！！！
第一版本是官方没有改写代码的版本支持的2M FLASH
实际可用的文件系统只有1.4M！
如果你用的芯片是国产4M、8M、16M 的 损失的空间就会更多！
所以大家要清楚，要根据自己手里的芯片进行定制开发，才能符合自己的标准，尤其是大项目，代码写的比较多，没有足够的空间肯定是不行的！
修改某些代码后，就可以释放芯片的最大空间！
