ESP8266 Community Forum

- Sun Jan 24, 2016 6:04 am #39558 I'm having issues getting basic programs running on my ESP8266. I've tried with really basic code that just prints some lines to trying to connect to the network, always resulting in some quick successive reboots from the module and eventually stalling completely. Output on start:

Sometimes an extra fatal exception is printed before the gibberish:

Code: Select allFatal exception (9):
epc1=0x40261bbc
epc2=0x00000000
epc3=0x401006a8
epcvaddr=0x3ffe802b
depc=0x40101b03

0x40261bbc in a disassembly seems to be ppTask, which looks like a method from the RTOS SDK related to WiFi? I don't know where I could continue with this issue to try and get code on my ESP8266 working, does anyone have any idea what could be wrong?
