RS232 固件编译

开始编译

固件编译简明指南

注意事项

• 网络: 确保上位机(树莓派等)已联网
• 登录方式: 必须使用 SSH 通过网络登录，禁用串口
• 输入法: 保持键盘为英文半角模式

---

SSH登录与用户切换

使用 MobaXterm、PuTTY 等工具 SSH 登录上位机。

切换用户：

• 普通系统(树莓派官方系统等)
  禁止使用 root,需切换到普通用户：

  su <用户名>

• FLY上位机(FlyOS-FAST系统)
  仅支持 root 用户登录(密码： mellow)

固件编译操作指南

在 Klipper 固件配置界面中仅支持键盘操作,无法使用鼠标。

按键	功能
↑ / ↓	上下移动光标，选择菜单项
Enter / 空格	确认选择、勾选选项或进入子菜单
ESC	返回上一级菜单
Q	退出配置界面
Y	退出时，如有提示则按 Y 保存配置

开始固件编译

下面介绍如何编译固件：

1. 连接到 SSH，输入下面的命令并按 Enter：

   cd ~/klipper && rm -rf ~/klipper/.config && rm -rf ~/klipper/out && make menuconfig

   其中，rm -rf ~/klipper/.config && rm -rf ~/klipper/out 用于清除之前的编译配置与固件； make menuconfig 用于打开 Klipper 固件配置界面。

2. 按照下方顺序逐项设置，每完成一项再继续下一项。

3. 完成上方最后两个步骤，按 Q 退出配置界面，再按 Y 保存配置。

4. 返回命令行后输入下面的命令并按 Enter 开始编译：

   make -j4

   root@flyos-11e5f8 ~/klipper # make -j4

   Preprocessing out/src/generic/armcm_link.ld

   Building out/compile_time_request.o

   Version: XXXX

   Linking out/klipper.elf

   Creating bin file out/klipper.bin

   终端末尾出现 Linking out/klipper.elf 和 Creating bin file out/klipper.bin，即表示编译成功。 实际编译时，部分 Compiling 行和 Version 会随 Klipper 与系统版本变化。

进入烧录模式

提示

上方为RESET按键,下方为BOOT按键

• 进入DFU有两种方法
• 第一种:在主板完全断电情况下,按住BOOT按键然后将带有数据传输的数据线一头接主板一头接上位机
• 第二种:在将带有数据传输的数据线一头接主板一头接你上位机,按住BOOT键然后按下RST键,然后松开RST键最后松开BOOT键

烧录固件

1. 安装烧录工具

• FLY上位机无需安装烧录工具
• 如果你需要安装请注意：上位机需要能上网才可以正常安装
• 如果已经安装过则无需安装

sudo apt update
sudo apt install dfu-util -y

2. 执行下面的命令查看是否连接成功。

lsusb

• 如果没有DFU设备请尝试重新进入烧录模式

• 因系统版本问题可能显示其他名字，如果有0483:df11则代表进入烧录模式

  Loading...

3. 烧录固件

• 执行下方代码开始烧录，请将 <固件文件完整路径> 替换为实际固件文件路径

sudo dfu-util -a 0 -d 0483:df11 --dfuse-address 0x08000000 -D <固件文件完整路径>

4. 出现下图内容File downloaded successfully则烧录成功

提示

烧录完成后，需要给主板彻底断电一次。

确认固件是否启动

• 如果固件正常启动LED会亮起来
