/* * "Hello World" example. * * This example prints 'Hello from Nios II' to the STDOUT stream. It runs on * the Nios II 'standard', 'full_featured', 'fast', and 'low_cost' example * designs. It runs with or without the MicroC/OS-II RTOS and requires a STDOUT * device in your system's hardware. * The memory footprint of this hosted application is ~69 kbytes by default * using the standard reference design. * * For a reduced footprint version of this template, and an explanation of how * to reduce the memory footprint for a given application, see the * "small_hello_world" template. * */#include "stdio.h"#include "system.h"#include "alt_types.h"#include "sys/alt_flash.h"#include "D:\mychengxv\flash\software\hello_world_0\udata.h"#define  BUF_SIZE 5int main( ){   alt_flash_fd *fd;   int   ret_code;   int   i;   extern int A[BUF_SIZE];   int nDest[BUF_SIZE];        fd = alt_flash_open_dev("/dev/cfi_flash_0");   if(fd)   {      ret_code = alt_write_flash(fd, 0, u2, 20);      if(!ret_code)      {         printf("Write flash successful!\n");         ret_code = alt_read_flash(fd, 0, nDest, 20);         if(!ret_code)         {             printf("Read flash successful!\n");             for(i=0; i<5; i++)             {                             {printf("%d ",nDest[i]);}                 printf("\n");             }                        }               }      else          printf("Write failed");      alt_flash_close_dev(fd);   }   else       printf("Open flash failed");//printf("Open flash failed");      return 0;}
