问题：使用独立电源通电，TF卡是闪迪32GB-A1，已按照官方镜像烧录多次。通电后串口数据输出正常。但绿灯常亮无法进入系统，连接HDMI，显示器也无输出。
烧录工具:balenaEtcher
镜像：官方桌面版镜像和服务器镜像 system_sdcard.img
串口数据如下：
我的也是无法进入系统，隔了几周没用，现在通电屏幕没有任何显示，压根就没有开机的信号，原来都还可以用的
您好，从您反馈的log来看似乎是检查启动介质，您可以用mmc list命令看一下，是否有带（SD）的选项，类似于“dwmmc@A5012000: 2 (SD)”。如果没有建议您那边换一下TF卡再尝试看看。
您好，不好意思久等了，已经收到问题，我们尽快同事帮忙解决
log如下，打印都没有报错信息

我也一样
旭日X3派更新最小启动固件 (horizon.ai)，您按照该教程中的刷机工具更新重新烧录一下最小启动镜像再尝试看看
烧录最小镜像，卡在这里不动，试了好几次都这样
您确认一下，板子是2G还是4G的，确定好版本烧录，烧录过程中出现上电提醒后再上电
