CC3200-LAUNCHXL: CC3200

Hi,

I am working on file operations project to read/wrirte from SFlash on CC3200 dev board. I have loading a file(test.txt) into SFlash using CCS UniFlash. I am able to read the file(test.txt) using file operations project,

but when i integrate the file operations functions into wlan_station project,i am unable to open the file using function

lRetVal = sl_FsOpen((unsigned char *) USER_FILE_NAME, FS_MODE_OPEN_READ, &ulToken, &lFileHandle); 

which returns the (i.e IRetVal) value -100.

any help will be highly appreciated. 

Regards,

Shafi
