Serial port 无法停止U-Boot自动启动
背景： 我有一个旧的Seagate BlackArmor NAS 110，我正试图按照以下说明安装Debian: 我有两个USB到TTL的串行适配器（一个是FTDI芯片组，另一个是多产的），我试过了，但都遇到了同样的问题。我已使用万用表连接到NAS板上的串行端口，以确保引脚正确 问题： 在启动过程中，我无法通过按键和任何点来停止自动启动过程。该设备似乎对任何按键都没有反应，尽管它们会被回响 到目前为止我所尝试的：Serial port 无法停止U-Boot自动启动,serial-port,embedded-linux,bootloader,u-boot,nas,Serial Port,Embedded Linux,Bootloader,U Boot,Nas,背景： 我有一个旧的Seagate BlackArmor NAS 110，我正试图按照以下说明安装Debian: 我有两个USB到TTL的串行适配器（一个是FTDI芯片组，另一个是多产的），我试过了，但都遇到了同样的问题。我已使用万用表连接到NAS板上的串行端口，以确保引脚正确 问题： 在启动过程中，我无法通过按键和任何点来停止自动启动过程。该设备似乎对任何按键都没有反应，尽管它们会被回响 到目前为止我所尝试的： 使用带有两个不同芯片组的USB到TTL串行适配器 在两台不同的计算机（MacBo
- 使用带有两个不同芯片组的USB到TTL串行适配器
- 在两台不同的计算机（MacBook Pro和ThinkPad）上使用适配器
- 使用不同的操作系统（MacOS、Windows 10、Ubuntu 20.04）
- 使用不同的终端程序（Screen、Minicom、Putty）
- 关闭硬件和软件流控制
- 通过短接RX和TX引脚并看到击键回响来测试适配器的输出
- 命令似乎被发送到设备，就像我打字时看到我的命令回显一样（不确定这是否应该发生）
