20240810在荣品RK3588S-AHD开发板的预置Android13下挂载exFAT的256GB的TF卡
2024/8/10 21:19

缘起：当时比较便宜96.9￥/想看看256GB的TF卡的高速卡的效果，就在京东入手了3张三星的高速TF卡。最近在弄RK3588S，就拿来实测效果了！

三星（SAMSUNG）256GB TF(MicroSD)存储卡 EVO白卡 U3A2V30 手机平板行车记录仪游戏机内存卡 读160MB/s写120MB/s

确认RK3588S在Android13下可以直接挂载exFAT的256GB的TF卡。

    BusyBox is a multi-call binary that combines many common Unix
    utilities into a single executable.  Most people will create a
    link to busybox for each function they wish to use and BusyBox
    will act like whatever it was invoked as.
