First of all, thanks Ray and all others for your work on this project.
After 3 evenings trying to solve my problem, I see no other solution than to ask for your help. I am trying to upload opensprinkler master firmware in a esp8266 dev nodemcu.
I am using arduino IDE 1.8.9 with ESP8266 CORE 2.5.2. I have compiled using mainArduino.ino and flash the firmware without any errors via serial USB, however the ESP8266 crash and enter on cycling reset loop with this msg:
ets Jan 8 2013,rst cause:2, boot mode:(3,6)
load 0x4010f000, len 1384, room 16
others have been facing to this problem but on my case, I cannot solve it.
here attached my setup:
is it correct?
Thanks for your support
