I'm trying to use some code from the sample files and given libraries to create my own custom program. Upon startup, this is what I get:

Here is the only function called by main():
void test_gps(){
nrf_gnss_data_frame_t gps_data;
GPS_Init(&gps_data); //issue is here
// GPS_Enable(&gps_data);
// nvs_setup();
while(1){
// GPS_State_Machine(&gps_data, fs);
}
}
Here is GPS_Init:
void GPS_Init(nrf_gnss_data_frame_t* gps_data){
printk("Initializing GPS");
do_uart_output = true;
loc_id = 1;
gps_update_rate = 1000;
int rv = init_app();
if(rv) printk("error");
t_last_location_recorded = k_uptime_get();
GPS_Update_Rate(gps_update_rate);
printk("GPS Initialized");
}
and here is init_app:
int init_app(void)
{
u16_t fix_retry = 0;
u16_t fix_interval = 1;
u16_t nmea_mask = NRF_CONFIG_NMEA_GSV_MASK |
NRF_CONFIG_NMEA_GSA_MASK |
NRF_CONFIG_NMEA_GLL_MASK |
NRF_CONFIG_NMEA_GGA_MASK |
NRF_CONFIG_NMEA_RMC_MASK;
int retval;
if (enable_gps() != 0) {
printk("Failed to enable GPS\n");
return -1;
}
gps_socket = nrf_socket(NRF_AF_LOCAL, NRF_SOCK_DGRAM, NRF_PROTO_GNSS);
if (gps_socket >= 0) {
printk("Socket created\n");
} else {
printk("Could not init socket (err: %d)\n", gps_socket);
return -1;
}
retval = nrf_setsockopt(gps_socket,
NRF_SOL_GNSS,
NRF_SO_GNSS_FIX_RETRY,
&fix_retry,
sizeof(uint16_t));
if (retval != 0) {
printk("Failed to set fix retry value\n");
return -1;
}
retval = nrf_setsockopt(gps_socket,
NRF_SOL_GNSS,
NRF_SO_GNSS_FIX_INTERVAL,
&fix_interval,
sizeof(uint16_t));
if (retval != 0) {
printk("Failed to set fix interval value\n");
return -1;
}
retval = nrf_setsockopt(gps_socket,
NRF_SOL_GNSS,
NRF_SO_GNSS_NMEA_MASK,
&nmea_mask,
sizeof(uint16_t));
if (retval != 0) {
printk("Failed to set nmea mask\n");
return -1;
}
// delay(5000);
retval = nrf_setsockopt(gps_socket, // This call causes problems
NRF_SOL_GNSS,
NRF_SO_GNSS_START,
NULL,
0);
if (retval != 0) {
printk("Failed to start GPS\n");
return -1;
}
return 0;
}
About 2 seconds after "GPS Initialized" is printed, the error pops up.
I also noticed when commenting out this line:
retval = nrf_setsockopt(gps_socket, // This call yields problems
NRF_SOL_GNSS,
NRF_SO_GNSS_START,
NULL,
0);
if (retval != 0) {
printk("Failed to start GPS\n");
return -1;
}
the error does not occur.
Everything builds without errors. I've tried building the project & spm together with the merged.hex and building them separately with .elf files, and both ways yield the Hard Fault. What are the steps to resolve this issue?
Thanks
