我正在尝试让 Mender.io 工作，这是一个远程更新系统。我只想看到设备出现在服务器上，不知何故那没有发生。我在apalis imx6上从源代码安装了mender，我试图像这样运行它：mender -daemon
它启动正常，然后给我以下错误：
INFO[0180] State transition: check-wait [Idle] -> inventory-update [Sync] module=mender

我已经添加了使用 etc/mender/server.crt 中提供的 keygen 生成的证书，并使用 ./up 启动了 docker 服务器我也没有在设备下看到我的设备。
我还能做什么？
