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
