无法停止 U-Boot 自动引导
Having trouble stopping U-Boot autoboot
背景：
我有一台旧的 Seagate BlackArmor NAS 110，我正尝试按照此处的说明在其上安装 Debian：https://github.com/hn/seagate-blackarmor-nas。
我有几个 USB 转 TTL 串行适配器（一个 FTDI 芯片组和另一个 Prolific），我已经尝试过 运行 两者都遇到了同样的问题。我已经使用万用表连接到 NAS 板上的串行端口，以确保我的引脚分配正确。
问题：
我无法通过按键和启动过程中的任何点来停止自动启动过程。该设备似乎也没有响应任何击键，尽管它们被回显。
到目前为止我尝试过的内容：
- 在两个不同的芯片组上使用 USB 转 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 引脚测试适配器的输出并看到击键回显
- 命令似乎被发送到设备，因为当我键入时我看到我的命令被回显（不确定这是否应该发生）
我已经研究了几天了，还是想不通。在遇到问题时，我还记录了我的屏幕：https://streamable.com/xl43br。谁能看出我哪里出错了？
遇到问题时的终端输出：
