fmount fails when fs_config moved to ext. RAM

Dear Keil Support Team

I'm facing a problem with the File System Driver and SD Cards.
For memory optimizations I moved the FS_CONFIG.o (+ZI) section to the external RAM.
However, if I'm doing so a cannot write to the SD Card and sometimes even fmount() fails with an fsMediaError. NAND acces works fine.
If I move the FS_CONFIG.o (+ZI) back to the internal RAM everything works.

What is neccessary to do if I want to move this section?

Thak you in advance for your help.

Regards
Benjamin
