Guys,

I have something strange when I tried to play a file for the first time,

on USART it gives me

	FR_NOT_READY,			/* (3) The physical drive cannot work */

but if I reset the MCU, it's working properly,
it happens always when it's starting from zero ( no power )

Do I need to reset it by software ?
Is it possible ?
I tried with watchdog reset but, it's resetting itself repeatedly, I want to reset it one time only and then start normally and may be I can fix the bug ?...

Any experiences like this ?
Thanks for the clue

You need to identify the root cause, not try to workaround with resets. Most likely is something is not initialised properly. Work backwards and identify where it goes wrong.
