Accesing PC files from UART

Hi everybody,

I am working in a project that requires sending datas stored in an internal register implemented into the FPGA to a file in a PC (W-XP). I think the best way is using the UART (11500 kbs).

however, when I try to access into a file in the computer from Nios, just for training, it doesn't work. I always receive the message "Cannot open file".

I use the UP3 Education kit.

Any idea? Thank you very much.

Roberto.

The code I download to the Nios is written below:

# include <stdio.h># include <stddef.h># include <stdlib.h>

# define BUF_SIZE (10)

int main(void)

{

FILE* fp;

char buffer[BUF_SIZE];

fp=fopen("/prueba/test.txt", "r");

if (fp==NULL)

{

printf("Cannot open file. \n");

exit(1);

}

fread (buffer, BUF_SIZE, 1, fp);

fclose(fp);

return 0;

}
