I am trying to gain access to the filename of files I read and write to the sdCard, without GUI intervention. These files will have application configuration data in them, or be used for data-logging.
I don't see any way to do this without customising CircleOS. So, I have rebuilt CircleOS from source, and re-programmed my EvoPrimer successfully.
However, I can't access my new CircleOS function within my user application. The user application fails to compile :

To rebuild CircleOS :
1. I added the new function in fs.c/fs.h.
2. I updated circle_api.h to contain :
#define FS_SET_SD_CURRENT_PATH_ID (FS_ID+14) /* Get the current path of the SDCard*/
&
#define FS_SetSDCardCurrentPath() (u32) (((tCircleFunc1)(Circle_API [FS_SET_SD_CURRENT_PATH_ID])) ((u8) (a))) /* void FS_SetSDCardCurrentPath (u8 *pathName);*/
3. I updated circle_api.c to contain :
( tCircleFunc0 )FS_SetSDCardCurrentPath,
then rebuilt CircleOS.
The updated circle_api.h is pointed to within the user application project setup.
Can anyone help explain the application compilation error, or point out anything I've done wrongly in rebuilding CircleOS?
