About FatFs Return FR_NOT_ENABLED

[wu ryan]

I use stm32F746 & FreeRTOS & SDMMC & DMA.

​

When I use f_open in somewhere it will return FR_NOT_ENABLED...

​

But in my system have the other f_open & f_write is normal work(I am not remount).

​

My English is not very good,if anything can't understand please tell me.

​

Thanks in advance
