eCos Configuration Tool



Hi All;

     I'm trying to do the memory test on the board with 256k SRAM; the code is
very simple as start a location write to it and read right out by printf:

....
#define START_RAM_ADD  ((volatile U8 *) 0x00000000)
....
U8 *ram_add;
.....
 ram_add=START_RAM_ADD;   /* assign the pointer to the beginning of add */

 for(n=0;n<1000;n++)  {
       *ram_add = 0xAD;                      /* Write to the address a hex value
 AD */
       printf ("%d RAM address %08X %02X \n", n, ram_add, *ram_add);
       ram_add++;                                  /* Increase the address
location */
}

The problem is that the output is always stop at 0x340 sometime at 0x345 (around
800 some bytes...)

1/ Is the problem come from my eCos configuration setup limit the amonut of RAM;
if yes, where do I change in the configuration; or what item in configuratool
should be change.

2/ Does eCos has ready code to run for RAM test, If yes please show where can I
get the code.

Any Assistance is Very Appreciated;
Diem
