Flash Test

hi everybody,

iam using a nios II system generated from sopc builder.my system contains

a CFI FLASH and SDRAM.Iam trying to simulate THE MEMTESTC.C exemple from the IDE.the sdram test is allright but the flash test is not.

I have an error in Modelsim "

-ERROR: Could not open flash

i think that the problem is in the function

alt_flash_open_dev witch don't recognize the flash

i changed the code a little bit to be a ble to simulate

static

void TestFlash(int mode, int flash_type)

{

alt_flash_fd* fd;

int number_of_regions;

int block;

int y=0;

flash_region* regions;

int ret_code = 0x0;

// alt_u8 entry[4];

alt_u8 flashname[30];i replace this variable by CFI_FLASH_NAME

printf(

"\n get flash name\n");

ret_code = GetFlashName(CFI_FLASH_NAME,CFI);

printf("\n openning the falsh\n");

fd = alt_flash_open_dev(CFI_FLASH_NAME);

if (fd)

{

printf(" -Successfully opened %s\n", CFI_FLASH_NAME);

/* Get some useful info about the flash */

ret_code = alt_get_flash_info(fd, &regions, &number_of_regions);

if (!ret_code)

{

printf(" -Region 0 contains %d blocks.\n", regions->number_of_blocks);

block = FlashFindErasedBlocks(fd, regions, number_of_regions, mode);

/* If we're in TEST mode, ask if this block is okay to test. */

if(( mode == TEST ) && ( block != QUIT_WITHOUT_TESTING ))

{

printf(" -Block %d, at address 0x%X identified.\n", block, (regions->offset + (block * regions->block_size)));

printf(" -Would you like to test this block? (y/n)");

//GetInputString(entry, sizeof(entry), stdin);

y=1;

// if ( entry[0] == 'y' && entry[1] == '\n' )

if(y==1)

{

/* Test that Flash! */

FlashRunTests(fd, block, regions);

printf(

" -Closing flash device \"%s\".\n",CFI_FLASH_NAME);

alt_flash_close_dev(fd);

}

}

}

}

else

{

printf(

" -ERROR: Could not open %s\n", CFI_FLASH_NAME);

}

}

i tried a lot of things and i get the same result

if somebody have an idea about how to solve this problem please HELP ME
