I am krishna,
I am using ESP8266 size of 4096KB, i want to upgrade my firmware using custom fota server.
Loaded user1.bin using NODEMCU FIRMWARE PROGRAMMER tool, and it is working fine.
And i kept user2.bin in my server, and i am able to down load the user2.bin(from address location : 0x81000), as i finish downloading i am calling system_upgrade_reboot(); function to upgrade but it is throwing an exception :
Code: Select all
2nd boot version : 1.4(b1)
SPI Speed : 40MHz
SPI Mode : DIO
SPI Flash Size & Map: 32Mbit(512KB+512KB)
