20250322在荣品的PRO-RK3566开发板的buildroot系统下读写TF卡
2025/3/22 9:25

缘起：荣品的PRO-RK3566开发板的buildroot系统，支持FAT32格式的TF卡的热插拔。
至少热插入是可以检测到的！^_

FAT32 实测可读可写。
NTFS  在RK3588平台只读。
ext4  在RK3588平台默认支持。
exFAT 在RK3588平台需要在内核打开配置文件。

@程帅?NTFS格式的TF默认挂载之后 只读？
重新挂载 也是的？

linux R4默认不支持exFAT？NTFS只读。由于是128GB的TF卡，我格式化为ext4能用了/自动挂载了
