USB 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。

   Quit

   Save configuration?

   (Y)es(N)o(C)ancel

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

   Compiling out/src/stm32/stm32h7_adc.o

   Compiling out/src/stm32/stm32h7_spi.o

   Compiling out/src/stm32/stm32f0_i2c.o

   Compiling out/src/stm32/usbotg.o

   Compiling out/src/stm32/chipid.o

   Compiling out/src/generic/usb_cdc.o

   Compiling out/src/stm32/hard_pwm.o

   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。

烧录固件

准备工作

• 开始烧录固件前，请先使用网络连接SSH
• 杂牌内存卡可能导致烧录失败，请尽量使用下方推荐的内存卡进行更新固件
• 需要准备一张容量不超过32G的TF卡，并且建议TF卡的传输速度必须为class10级或class10级以上，建议使用闪迪等品牌的TF卡

下载固件

1. 使用之前准备好的TF卡

2. 使用SDFormatter格式化

   Loading...

3. 使用MobaXterm_Personal左边文件目录找到klipper选择然后找到out打开

   • 普通系统固件下载目录
   • FlyOS-FAST系统固件下载目录

   注意

   • 普通系统注意事项
     • 树莓派、FLY派等普通上位机系统都看此类
     • 编译完成的固件在/home/<您的上位机用户名>/klipper/out/目录下
     Loading...

   注意

   • FlyOS-FAST系统注意事项
     • FAST系统的固件目录
     • 编译完成的固件在/data/klipper/out/目录下
     Loading...

4. 并且将klipper.bin下载到TF卡里面，并且重命名为firmware.bin

   firmware.bin

   Loading...

Windows 文件后缀显示

Windows 默认可能隐藏文件扩展名，容易把文件实际保存成 firmware.bin.txt 或 firmware.bin.bin。重命名固件前请在文件资源管理器中打开后缀显示：

1. 打开任意文件夹。
2. 点击顶部 查看。
3. 勾选 文件扩展名。
4. 重命名文件时确认完整文件名为 firmware.bin。

5. 主板断电，将TF卡插入主板
6. 给主板上电，等待10秒
7. 取下TF卡，插入电脑，如果SD卡中的firmware.bin消失，出现FLY.CUR就是烧录成功了

烧录后搜索 USB ID

固件烧录完成并给主板重新上电后，请继续搜索 USB ID。
