Wdt reset cause 4 on ESP8266-01 and NodeMCU1.0 #162

Hi guys,

I have a problem with your library, each time I add it to a sketch, it fail the wdt and reset like that :

wdt reset load 0x4010f000, len 1384, room 16 tail 8 chksum 0x2d csum 0x2d v09f0c112 ~ld

I've tested it with simple version 01 or 12E / Nodemcu and I've go the same problem.

I tried different programming speed and nodemcu v2 patch but nothing work.

Do someone know what to do ?

Thanks, Nicolas

1) Have you tried one of the simple samples and confirmed they work? 2) Are you using the Serial object? If so see issue https://github.com/Makuna/NeoPixelBus/issues/119 and read the wiki entry NeoEsp8266Dma800KbpsMethod which has the detail about serial.

if the samples work and you aren't using serial, then you need turn on debug features and get the stack (do a web search for "Arduino Esp8266 WDT crash stack"; it will entail sketch change and more. This will tell you where in your sketch the problem is happening.

Hi Makuna,

First thanks for your work, it's ok with sk6812-rgbw :) !

It works now, I can't explain, it's weird, but I found that when it is on a breadboard, it cause reset cause 0 or 4 (I think about contact vibration due to high frequency).

I'll test with crash stack debugger, I didn't know this existed before, thanks.

I've seen a routine for that :

  1. sketch boot -> wifi say connecting to XXXXX -> and then the dots stop and wdt reset
  2. sometimes it is ok without reboot.

I hope it will not occur when I'll make boards with that chip !
