Please use ESP Flash Download Tool to download the bin files into Flash.

Select "32Mbit" on the "Flash Size" area of the ESP Flash Download Tool while downloading.

If your problem is still unsolved, please feel free to let us know.

Thanks for your interest in ESP8266 !

http://bbs.espressif.com/viewtopic.php?f=7&t=865&p=2950&hilit=RTOS+FOTA#p2950
i am successfully generating the user1.bin and user2.bin by using the example code and i have flashed it by using the "esptool" by commend

Code:

esptool.py --port /dev/ttyUSB0 write_flash 0x00000 ESP8266_RTOS_SDK-master/bin/boot_v1.5.bin 0x3FC000 ESP8266_RTOS_SDK-master/bin/esp_init_data_default.bin 0x3FE000 ESP8266_RTOS_SDK-master/bin/blank.bin 0x01000 ESP8266_RTOS_SDK-master/bin/upgrade/user1.4096.new.4.bin


i have also add the "system_get_flash_size_map()" in the code to check the flash size map in "user_init()" function.

Code:

void ICACHE_FLASH_ATTR
user_init(void)
{
    printf("In blinkenTask ...\n");
    printf("Flash map value : %d\n",system_get_flash_size_map());


The output of the function is always "0" which is from rtos documentation.
For "0" it is "FLASH_SIZE_4M_MAP_256_256 Flash size : 4Mbits. Map : 256KBytes + 256KBytes"

enum flash_size_map
{
FLASH_SIZE_4M_MAP_256_256 Flash size : 4Mbits. Map : 256KBytes + 256KBytes -- 0
FLASH_SIZE_2M Flash size : 2Mbits. Map : 256KBytes
FLASH_SIZE_8M_MAP_512_512 Flash size : 8Mbits. Map : 512KBytes + 512KBytes
FLASH_SIZE_16M_MAP_512_512 Flash size : 16Mbits. Map : 512KBytes + 512KBytes
FLASH_SIZE_32M_MAP_512_512 Flash size : 32Mbits. Map : 512KBytes + 512KBytes
FLASH_SIZE_16M_MAP_1024_1024 Flash size : 16Mbits. Map : 1024KBytes + 1024KBytes
FLASH_SIZE_32M_MAP_1024_1024 Flash size : 32Mbits. Map : 1024KBytes + 1024KBytes
}


Is there is any way to generate the boot.bin for the Flash size 4096KB( 512KB+ 512KB).
Also i am able to download the user2.bin in the device from my local server and the my code uses the function
"spi_flash_write(addr, buffer, len)" to write the user2.bin in the memory address starts from "0x81000" as per the documentation to flash the file of size 4096KB( 512KB+ 512KB).. The spi_flash_write fails because the esp8266 device is in the (256kb + 256kb) flash mode, as we have flashed the boot.v1.5.bin. :D :D

what is the proper way to generate user1.bin, user2.bin. and boot.bin of flash size of 4096KB( 512KB+ 512KB), . Also when we make the project it only generates the corresponding user bin files only it is not generating the boot.bin files


bin crc: 767d457e
Support boot_v1.2 and +
Generate user1.4096.new.4.bin successully in BIN_PATH
boot.bin------------>0x00000
user1.4096.new.4.bin--->0x01000
!!!


Thanks in advance.. :D :D :D
