I have tested file service in esp8266 and it works fine.
but issue cause when i have included lwip's headers then fail to open file.

code snippet:

#include "esp_common.h"
#include "uart.h"
#include <fcntl.h>

// if include this files then file system not works.
#include "lwip/sockets.h"
#include "lwip/sys.h"
#include "lwip/netdb.h"
#include "lwip/dns.h"

#define Delay(ms) vTaskDelay(ms / portTICK_RATE_MS);

uint32 user_rf_cal_sector_set(void)
{
flash_size_map size_map = system_get_flash_size_map();
uint32 rf_cal_sec = 0;

switch (size_map) {
case FLASH_SIZE_4M_MAP_256_256:
rf_cal_sec = 128 - 5;
break;

case FLASH_SIZE_8M_MAP_512_512:
rf_cal_sec = 256 - 5;
break;

case FLASH_SIZE_16M_MAP_512_512:
case FLASH_SIZE_16M_MAP_1024_1024:
rf_cal_sec = 512 - 5;
break;

case FLASH_SIZE_32M_MAP_512_512:
case FLASH_SIZE_32M_MAP_1024_1024:
rf_cal_sec = 1024 - 5;
break;

default:
rf_cal_sec = 0;
break;
}

return rf_cal_sec;
}

spiffs_fs1_init();

xTaskCreate(spiffs_fs1_write_read, (const signed char *)"file_test", 512, NULL, 2, NULL);

}

output:

open file error error code = -1
write file error code =-1
read errno
--> <--
open file error error code = -1
write file error code =-1
read errno
--> <--
open file error error code = -1
write file error code =-1
read errno

Can any one have a idea what this happens.
