How can I change SPI clock in RL_FS pack?
I want to reduce this clock,My uSD card is not detected some times.fmount return FsMediaError or FsError.
I think configured clock is high.
I use the STM32f407.

Thanks.

    I change SPI clock prescaler after the mount. but it is not useful.
    I cant mount My memory card when its in FAT32(FSMediaError and FSError).this memory work without problem with FAT16 format.

    Whats the problem?
