wLED on ESP-12f Crashing

[nstiesi]

New user here. Just installed wLED on ESP-12f to drive a Ws2811 strip. Installation and setup went well and I just could not stop grinning as I was using it. However once I walked away I kept coming back to the default condition.

I tried bunch of stuff related to power supply, but nothing has worked. I thought at first the power was dipping, but I dont think that was it. I decided to monitor the serial port for exceptions and turned up the below every time it resets. I am not a coder by nature, so none of this means much to me, but I was hoping someone could help me figure this out? I have incorporated wLED into a larger project and it is almost done, I just need to push this over the line. Thanks!

To Reproduce
It is random, but crashes usually come in waves.

WLED version

• Board: ESP8266 2_7_4_7
• Version: wLED 0.12.0 build 2104020
• Format: Binary

Additional context
I have tried different power supplies. I have also tried a complete flash erase which seemed to help for a while, but ultimate the crashes came back with slightly different error codes

Thank you for your help!

Hi!
Sorry for the crashes!
How many LEDs are you running on what pin, and does this happen on one specific effect or can you reproduce it on different effects?
Exception 0 (Illegal instruction) is quite rare, it could be a problem with the flash memory. Do you have a second identical board to try?

I have 134 total leds in 44 groups of 3. Its a 12v ws2811 based strip that was cut to this length. The strip is being powered with 12V direct from an AC-DC (5A) supply. This supply powers a 2 channel CNC controller as well. The CNC controller has an on board 5V regulator, which feeds a 3.3V regulator on the ESP dev board.

The data is going through the default pin (gpio2, I believe). The crashes do not appear to be effect based. Its quite random. I had over 2 hours of uptime today, this after 5-10 crashes in the first 20 minutes of power on. Then one random crash, now I am back going on 45 minutes as of this writing.

I do have another esp-12f. The dev board is custom, and I broke a tool while cutting a new board for to try the other ESP, which ruined the last of my copper clad material, and I dont have great de-soldering skills or equipment. I ordered more material, as well as a couple Wemos D1 minis so I will have plenty to try come Tuesday if need be.

Today is the first day that I have had it running for an extended period. After multiple crashes in quick succession this morning, it seems to settle out to about once every 2-4 hours. Not sure if this information is of any real value toward solving the root cause.

Thanks!

Am having the same issue, random reboots on every single WLED setup. Am using the the NodeMCU microcontroller and it gets quite frustrating since I can't figure out the source and it feels random. It feels like it reboots more frequently when running effects.

Hey! This issue has been open for quite some time without any new comments now. It will be closed automatically in a week if no further activity occurs.
Thank you for using WLED!
