# EDL 设备管理器枚举

如果存储为空或已损坏，设备在通电时会切换到 EDL 模式。

要验证设备是否处于 EDL 模式，请运行以下命令：

```text theme={null}
PCAT -Devices
```

下图显示了设备状态为 EDL。

<div style={{ textAlign: 'center', width: '100%' }}>
  <img src="https://mintcdn.com/qualcomm-staging/uWQLnBcS9sxlZhgB/System/Boot/media/k2c-qli-boot/edl-enumeration.svg?fit=max&auto=format&n=uWQLnBcS9sxlZhgB&q=85&s=899e468716651a34554af42acc4f827d" alt="EDL 枚举" style={{ display: 'block', margin: '0 auto' }} width="1128" height="219" data-path="System/Boot/media/k2c-qli-boot/edl-enumeration.svg" />
</div>

检测到 EDL 后，使用 [Qualcomm Product Configuration Assistant Tool (PCAT)](https://qpm.qualcomm.com/#/main/tools/details/PCAT) 加载构建。
