Using fatfs on NOR flash will not work. a) fatfs has no wear leveling. b) fatfs lacks the concept of erase blocks. The SST39VF3201 has an erase block size of 4KBytes, which is more than the 512 Bytes FAT sector size. 0 Kudos. WebFeb 1, 2024 · 最后一键挂载。就是这个接口把fatfs和sd spi设备关联起来了,之后就可以使用fatfs的原生接口或者通过c标准库和posix函数对sd卡进行文件读写操作了,在这里就不展示了,大家在调试时可以操作一下。 到此,fatfs已经挂载起来了,完成了我们的第一步操作。
