I managed to implement a ESP8266 initiated firmware upgrade using SDK's upgrade function system_upgrade_start; This for me is the more useful use case, as the nodes will be able to check for new firmware version hosted on a central repository and reflash themselves wherever they are, even behind firewalls.
Will post code in a while

Nice, I am looking forward for the code! It comes down to two very different use-cases: pushing new FW in development mode vs. pull updates in "production" mode.

Hi again tve
Thanks for the continous blogging about the bootloader/OTA, it's very interresting to read.
Have you given any thought to maybe write the configuration structure to 2 different flash pages?
It's no big deal since I can change the code myself if I'll ues it for a project, I just thought it might be wise if it's to be used in a real mass produced product.
Again, thanks for all your hard work.

Sorry, which configuration structure? There currently is no configuration saved in flash other than the system config, which the SDK manages. I believe that what you are referring to is described in the "advice" sections of the Espressif document 99A-ESP8266__Flash_RW_Operation__EN_v0.2.pdf
I'll have to cross that bridge soon...
