RL-ARM filesystem and SDRAM

Anybody using the file system with RTX o/s, saving data to SDRAM.

Have board 32MB SDRAM on DYCS0 map the memory in none RTX mode the code runs fine and can read write to files.

In RTX mode application hangs at finit(), when application is stopped its in the DAbt_Handler.

The code none RTX is really simple

int main (void) {

        int i;

        FILE *f_p, *f_rp;
        char line[80];

                while( 0 != finit() );

                i = fformat("R:");


                f_p = fopen("R:\\temp\test.txt", "w" );

                if (f_p != NULL){

                 fputs("Example of a string in ram.\n", f_p);


                 fclose(f_p);

                }

                //re open the file to read back
                f_rp = fopen("R:\\temp\test.txt", "r" );

                if (f_rp != NULL){

                        fgets(line, sizeof(line), f_rp);

                        fclose(f_rp);
                }

}

The RTX version

_task void init (void){




                int i;




                os_tsk_prio_self (100);




                while( 0 != finit() );




                i = fformat("R:");




                os_tsk_create (timer_task, 40);




                os_tsk_delete_self();




}





int main (void) {
                os_sys_init(init);
                while(1);
}

The have increased the heap size, not using microlib, Imported swi_handler (i have used RTX before and the file system but not to SDRAM, previously use SDCARD).

Just after any pointers if anybody has some to share, bang head is getting painfull.
