Basic_Ota example not working in ESP8266

[Asanga-Viraj]

I tested Basic_Ota example in ESP8266. I commented RBOOT_TWO_ROMS in component.mk. Flashed the firmware to the ESP8266 and started Ota server in my PC using make otaserver command. Then did ota update via typing 'ota' on serial terminal when ESP8266 boot on rom0. Then set the settings to run on rom1. It worked successfully.

If I do ota updated when boot on rom1, the ESP8266 crashes. The output is below.

Another issue. Then I set ESP to run in rom0. When I change some parts of the example code (like adding serial print), recompile and restart the otaserver. The ESP8266 does the ota update successfully, but during restart, it runs until boot rom check (rom0 or rom1 to start), them crashes.

Can you help me with this.
