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。

   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

• 使用Type-C数据线将主板连接至上位机后,双击RST按钮,此时主板上会有LED灯闪烁。

烧录固件

开始烧录

• 非Fly官方上位机需要安装Katapult
• 安装Katapult

获取主板ID

执行以下命令搜索设备ID,正常情况应显示类似下图的ID(注意：每张主板的ID都不同):

ls /dev/serial/by-id/*

搜索出来的ID中包含了usb-katapult_stm32xxxxxxxx,则代表可以下一步

烧录固件

⚠️ 准备工作

• 请确保已编译好固件文件
• 将下方命令中的 <你的主板ID> 替换为上一步查询到的实际ID

• 普通上位机请使用下方代码

  ~/klippy-env/bin/python ~/katapult/scripts/flashtool.py -d <你的主板ID>

• FLY上位机请使用下方代码

  python3 ~/katapult/scripts/flashtool.py -d <你的主板ID>

固件更新

• USB固件更新
• 桥接CAN固件更新

USB固件更新步骤

1. 查询主板ID

ls /dev/serial/by-id/*

识别要点

下图中的 /dev/serial/by-id/usb-katapult_rp2040_E662549553642032-if00 即为主板ID

Loading...

2. 更新固件

cd ~/klipper/ && make flash FLASH_DEVICE=<你的主板ID>

注意

• 请将 <你的主板ID> 替换为实际查询到的ID

Loading...

桥接CAN固件更新步骤

1. 重置进入烧录模式

重要提示

<你的主板ID> 为 printer.cfg 配置文件中主板的 CANBUS UUID

• 普通上位机请使用下方代码

  ~/klippy-env/bin/python3 ~/katapult/scripts/flashtool.py -i can0 -r -u <你的主板ID>

• FLY上位机请使用下方代码

  python3 ~/katapult/scripts/flashtool.py -i can0 -r -u <你的主板ID>

示例说明

下图中的 f95cee90e1f9 为主板的 CANBUS UUID(仅作示例)

Loading...

2. 查询新的设备ID

ls /dev/serial/by-id/*

识别要点

• 这只是参考！
• 下图中的 /dev/serial/by-id/usb-Klipper_stm32f072xb_38001B000551324752333720-if00 即为新识别的主板ID

3. 烧录新固件

cd ~/klipper/ && make flash FLASH_DEVICE=<你的主板ID>

刷错固件的解决方法

方法一：快速进入烧录模式

1. 主板断电
2. 重新上电后,快速双击RESET按钮
3. 重新进入烧录模式

方法二：重新烧录Katapult固件

点击查看Katapult固件烧录指南

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。
