Working with SD Card,Help needed

Hi All,

I am working on the MCBSTM32F200 Evaluation board, after i installed the enviroment i opened the example "SD_File" that dimostrates how to work with a filesystem.

Unfortunatly when i tried to compile i recived the following message :

.\Obj\SD_File.axf: Error: L9937E: RL-ARM is not allowed with this license

I know that i have the evaluation license .
My question is as follows : do i need the additional library ( meaning that i should by a license) , or there is another way to config and work with the SD Card.

on my project i just tried to use fopen function , but as far as i saw the program just crashed somewere.

Best regards
Michael
