Colleagues,
Was happily using opensprinkler in pi zero, but suddenly stopped working. Pi is dead and the issue is that I can not get a spare, so trying to move to ESP8266 HW . I do have 12F version. Downloaded the compiled file for ver 3.0 from here http://raysfiles.com/os_compiled_firmware/v3.0/ os_219_rev9.bin . Used the Express ESP flash tool, and followed this procedure https://www.allaboutcircuits.com/projects/flashing-the-ESP-01-firmware-to-SDK-v2.0.0-is-easier-now/
My question here is the starting memory. In that page it states 0xFB000. Is this correct?
The issue I am having is continues reboot, (btw, did not see any error on flashing the esp8266) and the blue led is flashing rapidly

Finally, at this point I do not have any HW attached to the ESP8266-12F . I would need the RTC + PCF8574. Is it possible this behavior because I do not have connected that HW?
Any idea what night be wrong?
Cheers,
