20260128让天启AIO-3576Q38开发板在Rockchip瑞芯微原厂Buildroot下读写TF卡-写入20MBps
2026/1/28 15:16

缘起：让天启AIO-3576Q38开发板在Rockchip瑞芯微原厂Buildroot下读写TF卡。
可以看到默认编译的Buildroot即支持热插拔TF卡。
当你插入TF卡的时候，默认将TF卡挂载到 /sdcard 目录。
1.6GB的大文件的测试读写：读取10s+，写入80s。读取160MBps/写入20MBps

当你把荣品RD-RK3588开发板重新适配一把，就相当于从头做了一个项目：【荣品RD-RK3588开发板】。
当然，开发板的功能都是好的，你免除了调试的过程，也就没有解决相关硬件出错的经验/机会了！

1、200MB的mp4视频的测试读写：读取4s，写入5s。读取50MBps/写入40MBps
