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
