Hello,

Please add this to your user_main.c:
Make sure that the corresponding sector contains blank.bin

Code: Select all

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 - 8;
            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;
}

I'ts worked for me.

But in the first line code i have removed "enum"

Code: Select all

from "enum flash_size_map size_map = system_get_flash_size_map()"
to "flash_size_map size_map = system_get_flash_size_map();"


Thanks for the answer...
