Why is my Zynq-7000 marine navigation system failing to initialize the NMEA 2000 GPS sensor?
I am developing a marine navigation system using a Zynq-7000 with Embedded Linux. The system should read data from an NMEA 2000 GPS sensor. I have confirmed the serial port connection and settings, checked the GPS sensor configuration and data format, made sure the NMEA 2000 library is correctly installed and configured. But i am getting the error Failed to initialize NMEA 2000
#include <stdio.h>
#include <nmea2000.h>

int main() {
NMEA2000 *nmea;
nmea = nmea2000_init("/dev/ttyUSB0");

if (nmea == NULL) {
fprintf(stderr, "Failed to initialize NMEA 2000\n");
return 1;
}

float latitude, longitude;
if (nmea2000_get_gps(nmea, &latitude, &longitude) != 0) {
fprintf(stderr, "Failed to read GPS data\n");
} else {
printf("Latitude: %f, Longitude: %f\n", latitude, longitude);
}

nmea2000_cleanup(nmea);
return 0;
}
