I know this seams like a newbie question but does the esp8285 SoC come boot strapped with a boot loader within it's internal flash from the factory?

I suppose that internal system ROM in the chip is located at 40000000 and contains basic system functions. In case if you have sdk please find a file "eagle.rom.addr.v6.ld" and it lists all the functions in there. That allows uart and download routines to program an external flash. I think It reads the 3 GPIO boot mode pins.
