crashing from _start without even entering into main() function

[swetha Paladugu]

Hi,

I am using nrf52832 custom board and sdk17.2.0.

My application is a Freertos application. I see that my application is going to hardfault from _start without entering into the main() function.

Attached sdk_config.h , FreeRTOSConfig.h and the screenshot of the hardfault for reference.

Can someone please help me to resolve the issue?

that didn't solve the issue.

rtc_t nowTime;

struct tm t1;

uint32_t get_current_time(void)
{
get_time(&nowTime);

// struct tm t1 = {.tm_year = RTC_Bcd2ToByte(nowTime.year) + BASE_YEAR,
// .tm_mon = RTC_Bcd2ToByte(nowTime.month) - 1, /* In C, Jan = 0 */
// .tm_mday = RTC_Bcd2ToByte(nowTime.days),
// .tm_wday = RTC_Bcd2ToByte(nowTime.weekDay),
// .tm_hour = RTC_Bcd2ToByte(nowTime.hour),
// .tm_min = RTC_Bcd2ToByte(nowTime.min),
// .tm_sec = RTC_Bcd2ToByte(nowTime.sec)};

t1.tm_year = RTC_Bcd2ToByte(nowTime.year) + BASE_YEAR,
t1.tm_mon = RTC_Bcd2ToByte(nowTime.month) - 1, /* In C, Jan = 0 */
t1.tm_mday = RTC_Bcd2ToByte(nowTime.days),
t1.tm_wday = RTC_Bcd2ToByte(nowTime.weekDay),
t1.tm_hour = RTC_Bcd2ToByte(nowTime.hour),
t1.tm_min = RTC_Bcd2ToByte(nowTime.min),
t1.tm_sec = RTC_Bcd2ToByte(nowTime.sec);

return (mktime(&t1));

}

And same issue is coming even on calling the below set current time function, with ctime and localtime. With this what i observe is there is some issue using the time.h functions. Do i have to enable any macros or add any paths to the project? 

void set_current_time(time_t current_time)
{
ctime(&current_time);

struct tm ts = *localtime(&current_time);
rtc_t time_to_rtc = {.sec = RTC_ByteToBcd2(ts.tm_sec),
.min = RTC_ByteToBcd2(ts.tm_min),
.hour = RTC_ByteToBcd2(ts.tm_hour),
.days = RTC_ByteToBcd2(ts.tm_mday),
.weekDay = RTC_ByteToBcd2(ts.tm_wday),
.month = RTC_ByteToBcd2(ts.tm_mon + 1),
.year = RTC_ByteToBcd2(ts.tm_year - BASE_YEAR)};

set_time(&time_to_rtc);
}

Those API are working quite fine on my end with the nRF5_SDK_17.0.2_d674dde\examples\ble_peripheral\experimental\ble_app_cgms example.

FreeRTOS should not have any role in this behavior except the stack sizes I mentioned before. So I am not sure what causes the issue you are seeing.

The issue got resolved.

I have added -rtos GDBServer\RTOSPlugin_FreeRTOS this to my debugger settings for debugging crashes between threads, after removing this the issue got resolved. i am not sure how does that plugin affects those time.h api's.
