hi i’m wrtiting a code for a device that uses esp32 wroom it gets some numbers and sends them to a server i use arduino platform with platformio .Free RTOS is used in this code. When the code reaches to the section that is for converting the strings which are read from SPIFFS to numbers it crashes and sends this message in serial “abort() was called at PC 0x40158d07 on core 0” and then resets the esp32.
i can’t bring the whole code here because it too long but i can show some faulty parts and error and debug messages here.
i tried to debug the code and this is what i’m getting

the function convert_SPIFFS_read_string_to_number() is as follows :
void convert_SPIFFS_read_string_to_number(void)
{
string mac_send_spiffs_string(mac_send_vector_spiffs.begin(), mac_send_vector_spiffs.end());
for (int i = 0; i < mac_send_vector_spiffs.size(); i++)
{
printf("mac send vector is %c", mac_send_vector_spiffs[i]);
}
Serial.printf("mac send spiffs string is %s", mac_send_spiffs_string.c_str());
string entrance_spiffs_string(entrance_char_vector_spiffs.begin(), entrance_char_vector_spiffs.end());
string exit_spiffs_string(exit_char_vector_spiffs.begin(), exit_char_vector_spiffs.end());
for (int i = 0; i < exit_char_vector_spiffs.size(); i++)
{
printf("exit char vector spiffs is %c", exit_char_vector_spiffs[i]);
}
mac_send_input_mac = stoi(mac_send_spiffs_string);
Serial.printf("mac_send_input_mac is %i", mac_send_input_mac);
mac_send_input_mac_vect.push_back(mac_send_input_mac);
mac_send_input_entrance = stoul(entrance_spiffs_string);
Serial.printf("mac send input entrance is %lu",mac_send_input_entrance);
mac_send_input_entrance_vect.push_back(mac_send_input_entrance);
mac_send_input_exit = stoul(exit_spiffs_string);
Serial.printf("mac send input exit is %lu",mac_send_input_exit);
mac_send_input_exit_vect.push_back(mac_send_input_exit);
}
and this is part of the code that calls this function :
if (SPIFFS_SUCCESS == 1)
{
SendTo_Server_Status mac_send_status_in_success_clause;
SPIFFS_READ_EPOCH(enter_date);
SPIFFS_READ_EPOCH(exit_date);
SPIFFS_READ_MAC(mac_index);
convert_SPIFFS_read_string_to_number();
mac_send_status_in_success_clause = MAC_SEND_TO_SERVER(mac_send_input_entrance_vect[mac_index], mac_send_input_exit_vect[mac_index], mac_send_input_mac_vect[mac_index]);
if (mac_send_status_in_success_clause == DATA_SEND_SUCCESS)
{
SPIFFS_REMOVE_EPOCH(enter_date, mac_index);
SPIFFS_REMOVE_EPOCH(exit_date, mac_index);
}
else
{
SPIFFS_SUCCESS = 0;
NEED_SPIFFS_READING = 0;
}
}
what might cause this problem ? is it related to stack overflow ? or heap memory? or something else ? thanks in advanced
