[ECOS] Problems in programming in FLASH - EB40A

[Giri Raja <giri_amf at yahoo dot com>]

Hi,
   I'm using a simple test program to program and read
from the FLASH memory in EB40A. I have a buffer that
contains all the data that is needed to store in the
FLASH. when I make the type of this buffer to be a chr
array, then I do not get any problems. however if I
define it to be of type cyg_uint8 or unsigned chr,
then I'm not sure if the data is written into the
FLASH properly. I check the validity of the
flash_program by doing a flash_read and printing out
the contents. 
when the type was cyg_uint8 or unsigned chr, I see
only the first few bytes of the array written
properly, and then they keep repeating.

here is the code that I'm using.

#include <cyg/kernel/kapi.h>
#include <cyg/hal/hal_platform_ints.h>
#include <cyg/io/io.h>
#include <cyg/io/ttyio.h>
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <cyg/hal/hal_io.h>
#include <cyg/infra/diag.h>
#include <cyg/io/flash.h>
                                                      
                                                      
               
extern "C"  {
        void cyg_user_start(void);
}
                                                      
                                                      
               
void cyg_user_start(void)
{
        int err,i ;
        unsigned char input_bytes[10];
        int length;
        char *err_address ;
        unsigned char readStr[10] ;
        int p_base = 0x01030000;
                                                      
                                                      
               
        for(i = 0; i < 10; i++)
                input_bytes[i] = (unsigned
char)(i+10);
                                                      
                                                      
               
        flash_init(diag_printf);
        length = 10;
                                                      
                                                      
               
        for(i = 0; i < 10; i++)
                diag_printf("the chrs - input_byes[%d]
= %u\n", i, input_bytes[i]);
                                                      
                                                      
               
        err = flash_program((void *)&p_base, (void
*)input_bytes, length, (void **)&err_address);
                                                      
                                                      
               
        flash_read((void *)&p_base, (void *)readStr,
length, (void **)&err_address);
        for(i = 0; i < length; i++)
                diag_printf("byte[%d] = %u\n", i,
readStr[i]) ;
                                                      
                                                      
               
Thank you very much.

Giri.
