What problem are you exactly facing when handling the PCM files? Which APIs return error? Did you try our FatFs example project? If the pcm file is too large, please make sure that the reads, buffering and transferring to PC via USB are done in a sequential and well planned manner.

Thank you for the reply.
The problem is resolved. I was converting the buffer read to string unknowingly. That was the reason for the issue.
