[ECOS] comlib_gps_init( ) fails because of assertion

[ECOS] comlib_gps_init( ) fails because of assertion

[MapTrace bv]

Hi all,

I'm trying to write a gps test program for the Falcom F35. It seems to 
compile alright, but when I try a comlib_gps_init( ) it fails because of 
an assertion error. I believe the error message means the port number is 
too high, which I don't understand, because when I look at the source of 
serial.c, I see a '#define PORT_MAX 7' preprocessor directive. Does this 
indicate there's something wrong with my ComLib installation? I have 
included my program output, source and makefile. Any ideas?

Thanks,

Jaco Bregman

    comlib_init();
    comlib_gps_reset();

    while (result != STATUS_ALL_OK && nPort < 8) {
        printf("Switch to nmea on port %d...\n", nPort);
        result = comlib_gps_switch_to_nmea(nPort);

        if (result != STATUS_ALL_OK) {
            printf("Switch failed on port %d.\n", nPort);
        }

        nPort++;
    }

        nPort--;
        printf("Switch to nmea on port %i succeeded.\n", nPort);
        printf("Initializing gps...\n");
        result = comlib_gps_init(gpsModule, nPort, NULL, 0, 4);

        if (result == STATUS_ALL_OK) {
            comlib_gps_command(gpsModule, "PSRF103,00,00,00,01", 2);
        }
        else {

Sorry, but this has nothing [directly?] to do with eCos.  You
probably need to ask these questions somewhere else.
