Latest Update reset/restart issue

[henmel]

I am running into an issue with the latest update of the WS2812FX Library(1.2.4), along with the latest Arduino ESP8266 board library(2.7.1) update. I have included
esp8266_webinterface_testota-200524a.zip
a copy of Web Interface example with Arduino OTA added. When the sketch is uploaded via Arduino OTA, my NodeMCU ESP8266 continuously keeps resetting with:

12:14:02.732 ->  ets Jan  8 2013,rst cause:2, boot mode:(3,6)
12:14:02.732 -> 
12:14:02.732 -> load 0x4010f000, len 3456, room 16 
12:14:02.732 -> tail 0
12:14:02.732 -> chksum 0x84
12:14:02.732 -> csum 0x84
12:14:02.732 -> va5432625
12:14:02.732 -> ~ld

until I press the reset button on the NodeMCU, then it restarts normally. I also added a restart function to the web interface for testing, which appears to do the same thing as uploading over OTA. After doing a lot of testing, trying to narrow down the cause, it appears that the latest changes in the mode_running_lights, may have something to do with it, as changing the code to the old version of the effect resolves the issue.

Thanks in advance!

Your sketch works fine on my NodeMCU. Looks like you're a victim of this XMC flash bug:
esp8266/Arduino#7307

Some additional info here:
esp8266/Arduino#7267

There is a PR to fix this:
esp8266/Arduino#7317

Thank you for the quick response and reference links, but I am a bit confused about the fix. How do I install the Pull Request(PR)? Do I just uninstall then reinstall esp8266 board, using the board manager? I am sorry to be a bother, but this is still a bit new to me.

Unless you have a burning need for the 2.7.1 release, I would drop back to the 2.6.3 release. I would guess that the PR would go out in the 2.7.2 release, but not sure when that will be.

Thanks again for your quick help and a great library!
