固件升级
一、准备工作
- 1x microSD 卡(容量 >=16GB, 读写速率最低 class10，格式化为 FAT32 格式)，内容需要为空
- 1x microSD 读卡器
- 12V 电源适配器（在整机下安装系统镜像，整机供电12V）
- usb type-a转type-c数据线一条（用于日志输出打印）
二、升级流程
1、请点击 固件下载 网址下载卡刷升级包；
提示
下载路径为：ShiMetaPi社区项目 > ShiMetaPi AI智能硬件 > AIBOX-1684XB-32 > 01-系统镜像
2、在本地电脑先将压缩包解压后再拷贝至SD卡根目录下；
3、将sd卡插入卡槽，上电，按下power开机键，在串口中观察到如下log，就说明正在刷机，过程大约3~5分钟；
