本文主要是介绍玩客云emmc坏了别扔，还有其他用处，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
我的玩客云设备，在做绝育测试的时候，刷机过多把emcc刷坏了。在网上买了个芯片，在取旧芯片的时候把触点焊掉了。原文阅读

本想着，这下这玩客云彻底罢工了。带着折腾的精神，很多设备不是可以使用SD卡启动吗，就尝试把玩客云绝育后备份出来的磁盘镜像写入SD卡。
启动玩客云后在ttl里能跑码但会报错，如下：

这个可能得改UBOOT,可惜我不会。在网上找了一圈也没找到相关资料。最后找到一个支持SD卡启动linux系统的UBOOT，使用Win32DiskImager写入SD卡，下面是启动信息

可以从SD卡启动，还能从USB启动。在网上找到一个写好了UBOOT的系统Armbian_21.02.0-trunk_Aml-s812_bullseye_current_5.15.0-aml-s812-sd.7z直接用Win32DiskImager写入SD卡（文末提供下载）就可以使用了，当然为了速度快，可用用容量小的SD卡写入UBOOT-SD.bin，把系统写入U盘，这样运行速度要快些。当然也可以用UBOOT-SD.bin合成自己的镜像，可以作TV盒子，安卓系统，游戏系统。
合成方法：
linux下dd命令
dd if=UBOOT文件 of=镜像文件 conv=fsync,notrunc bs=1 count=444
dd if=UBOOT文件 of=镜像文件 conv=fsync,notrunc bs=512 skip=1 seek=1
可以正常使用Docker，那这可以玩性就多了。我先安装了个1panel面板。
1panel部署方法：
curl -sSL https://resource.fit2cloud.com/1panel/package/quick_start.sh -o quick_start.sh && bash quick_start.sh
https://nctoro.com/content/uploadfile/202310/5d4e1698133608.png
我安装的甜糖，看能不能赚点网费。如果有刷甜糖的，邀请码是527536
部署甜糖方法：
docker run -d -v /mnt/mmcblk0p1:/mnt/data/ttnode -v /var/run/docker.sock:/var/run/docker.sock -v /proc:/host/proc:ro --name ttnode --hostname ttnode --device /dev/mem --cap-add SYS_RAWIO --privileged --net=host --restart=always -e container_name=ttnode registry.cn-hangzhou.aliyuncs.com/tiptime/ttnode:latest
https://nctoro.com/content/uploadfile/202310/8cd31698134609.png
参数解释
-v /mnt/mmcblk0p1:/mnt/data/ttnode/mnt/host/dir
这里的/mnt/mmcblk0p1改为你的设备的缓存目录
-v /var/run/docker.sock:/var/run/docker.sock
支持自动更新，不设置则需要手动更新镜像
--name ttnode
容器名称，建议自行修改个比较独特的容器名称，尽量不与他人重复，避免冲突
-e container_name=ttnode
容器名称，需与上面的name保持一致，否则可能有启动业务失败
查看 ttnode 状态
docker container ls # 查看所有容器
浏览器
docker inspect 容器名 -f "{{json .NetworkSettings.Networks.macnet.IPAddress }}" # 查看容器ip http://容器IP:1024 # 浏览器 查看二维码 端口
命令行
docker logs -f 容器名 # 查看二维码 端口
删除 ttnode
docker rm -f 容器名 # 删除容器
检查 ttnode 挂载
docker inspect -f '{{ .Mounts }}' 容器名
预期 [{bind /mnt/host/dir /mnt/data/ttnode true rprivate} …]
左边是本机挂载目录 /mnt/host/dir ，右边必须是 /mnt/data/ttnode
还有很多功能可以用，可以在1panel面板应用中心安装Home Assistant做一个自己的智能家居自动化平台，断网也能自动控制家里的智能设备。比去卖一台控制中心性价比强多了。
