I am trying to read a file using NIOS with the eventual goal of loading that readdata into an EEPROM.
I have followed the instructions outlined in : https://www.intel.com/content/www/us/en/programmable/documentation/mwh1416947091611.html
I have gone to the BSP editor -> Software Packages and enabled altera_hostfs. The hostfs_name is /mnt/host
My code (included below) gets stuck at fopen but if I use the NIOSII debugger, I am able to step through the whole program and readout "Hello World" into the console. Any suggestions would be appreciated.
#include <stdio.h>
#include <alt_types.h>
#include <io.h>
#include <string.h>
#include <stdlib.h>
#include <unistd.h>
#define BUF_SIZE (12)
void main()
{
FILE* fp;
char buffer[BUF_SIZE];
printf("start\n");
fp = fopen("/mnt/host/read_test.txt", "r");
printf("fopen command\n");
if (fp == NULL)
{
printf ("connot open file for reading\n");
exit(1);
}
fread(buffer, BUF_SIZE, 1, fp);
fclose(fp);
printf("%s", buffer);
}
