build error using peripheral_test code

[shenhome]

Hello,

Below function was showed in user_main.c. It generates error when build .bin file.
Question: 1) why we need this function?
2) what should I do to solve this issue?




=========================================================================================
uint32 ICACHE_FLASH_ATTR
user_rf_cal_sector_set(void)
{

enum 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;
}

 * FunctionName : user_rf_cal_sector_set
 * Description  : SDK just reversed 4 sectors, used for rf init data and paramters.
 *                We add this function to force users to set rf cal sector, since
 *                we don't know which sector is free in user's application.
 *                sector map for last several sectors : ABCCC
 *                A : rf cal
