ESP8266 Reset

[bijilbaji]

ESP8266 resets when i try to change status of pin D6,D7 and D8. The pin mapping shows D6 as gpio12, D7 as gpio13 D8 as 15; I am using ESP library version 2.5.2. I think this might be conflict between Ethernet.h and ESP8266WiFi.h library. When it restarts there is not startup message. I tested it with dOPC explorer 2.0.0.261 and ArduinoOPCServer version 2.0, i also tesed it via browser the esp32 restarts without sending the response code back to the browser webpage. i am thinking of porting the code to work without the OPC library to avoid any conflics for both esp8266 and esp32.
