FlashDev / FlashPrg for STM32F107

Hello.

I'm trying to set up a MCBSTM32C to have a Flash File System using the RL-ARM FlashFS library, but i'm having a bit of trouble i hoped someone could help me sort out.

In the book "Building Applications with RL-ARM" under RL-Flash introduction, there's a section discussing how to set up a Flash-based filesystem.

It calls out for the file FS_FlashPrg.c and FS_FlashDev.h under the folder C:\KEIL\ARM\RL\FLASHFS\FLASH then a subdirectory named according to your flash or microcontroller.

Looking in that folder i have the following folders:

25F640S33
AM29x800BB
AM29x800BBx2
AM29x800BT
AM29x800BTx2
AT45DB321C
AT45DB642D
LPC_IAP_128
LPC_IAP_256
SST39x320x
STR71x
STR75x
STR91x

I'm not sure which one would correspond to the STM32F107VC... Do I have to write my own drivers for this controller? If so, is there literature i can obtain covering how to do this?

Thanks for any insight.

Some more information ...

If i try to use any memory area at 0x0802 5800 or higher, the program i have will hard fault with the call stack as follows.

HardFault_Handler()
<0800135e()>
fs_ReadData()
  adr <invisible>
  cnt <invisible>
  buf <invisible>
fs_Find_File()
  fname 0x00000000
  fcb 0x20000090
  fa 0x20000b9d8
  buf 0x2000b9b4
  bl 0x00000000
  prev <invisible>
  fid 0x0000bdf7
__fopen()
  fname 0x0800048a
  openmode <invisible>
  i <invisible>
  fid 0x2000b9b4
  handle 0x00000000
  fcb 0x20000090
  rval <invisible>
_sys_open()
  name <invisible>
  openmode <invisible>
<080010f2()>
main()

if i do not include any addresses above this, it behaves as such:

...
        fptr = fopen("F:\\test.txt", "w");
        if ( fptr != NULL )
        {
                r= fwrite("this is a test", 1, 14, fptr);
                r= fflush(fptr);
                r= fclose(fptr); // the code will run to here
        }

        fptr = fopen("F:\\test.txt", "r" );
        if ( fptr != NULL )
        {
                r= fread(sz, sizeof(char), 14, fptr);
                r= fflush(fptr);
                r= fclose(fptr); // the code will NOT run to here
        }

It seems the file is not written properly in the fwrite call?
