ESIGNUM while opening file on SD card using fopen() call

[aahsan]

I am seeing an intermittent error returned by fopen() call resulting in file open failure on the SD Card.

Wondering if someone has encountered this error while using STM32Hxxx and what could be the cause of this error.

Really appreciate your support

Thanks, and Best Regards,

Ahsan
