Subject: Reading from uSD Card using EFSL File System

Hello,

I am successfully able to read several packets of 512 bytes from uSD card using EFSL. But if I change the number of bytes to 417 or to some other number, I see some problem in the execution of my code. It hangs in the fn named ''ioman_releaseSector''. Is it that we can only have multiples of 512 as the number of bytes to read and otherwise it would cause suspension of some sector release.

Also, if I am missing something in code related to sector management.

Any help would be appreciated.

Regards,

Ankita

Hello Ankita,

I'm trying to read/write to my SD card using EFSL. Had not had much luck searching through ST site for an example code. You you be willing to share what you might have?

Thanks,

Ben
