My program get stuck in fopen() while trying to open the LCD HAL mount point.

Hello to everybody,

I try to implement 2 × 16 character display Lumex LCM-S01602DSR/C.

I used Nios II system and added lcd component.

Now i try to show some characters on lcd, here is my code.

but unfortunatelly, all i can see is uncoorect characters, they don't show any digits.

fopen works and it gives right pointer

How do you think what are the problems?

int main()

{

FILE * lcd;

lcd = fopen("/dev/lcd", "w");

if(lcd == NULL)

{

fprintf(stderr, "Failed to open LCD");

//exit(1);

}

//fprintf(stdout, "Hello on the LCD\n");

//fprintf(stdout, "1");

int i=0;

for (i=0; i< 7; i++){

fprintf(stdout, "7700");

fprintf(stderr, "1133");

fprintf(stdin, "4499");

}

fprintf(stdout, "\n");

fprintf(lcd, "[ 2 J");

// while (1){

// fprintf(lcd, "7700");

// }

fclose(lcd);

return 0;
