USB桥接CAN 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
    Compiling out/src/stm32/usbotg.o
    Compiling out/src/generic/canserial.o
    Compiling out/src/../lib/fast-hash/fasthash.o
    Compiling out/src/stm32/fdcan.o
    Compiling out/src/stm32/chipid.o
    Compiling out/src/generic/usb_canbus.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

    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...

  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。
  1. 主板断电，将TF卡插入主板
  2. 给主板上电，等待10秒
  3. 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 CAN ID​

固件烧录完成并给主板重新上电后，请继续搜索 CAN ID。
