Guru Meditation Error: Core 1 panic'ed if pin not available

[maxx-ukoo]

What happened?

I have board with ethernet. Ethernet chip use pins 16/17 for communication.
It looks like by default WLED use pin 16 as data pin for W28xx strips.
As result W28xx object not initialized properly and app crash on attempt of control leds. This lead to AP not available and it is not possible to fix config without full binary reflash.

To Reproduce Bug

Flash ethernet firmware on ethernet supported board with pin 16/17 as data pins and configure ethernet.

Expected Behavior

If data pin not available WLED shouldn't run effects on led object

Install Method

Self-Compiled

What version of WLED?

2412040 v4 eth build from https://github.com/wled/WLED/compare/0_15_x...maxx-ukoo:WLED:mk_0_15_0_RTL8201?expand=1 branch

Please use latest sources and compile from upstream.

Workaround is to define default GPIO for LEDs.

We should not be panic like this, there is code to check if the pin is available and we have checks like if (!_valid) return; so why are we still seeing the crash? Do you have the full crash log @maxx-ukoo ?

[netmindz]

Please can you check if my commit was enough to resolve the issue you were having @maxx-ukoo ?

@netmindz i broke esp32 prog board, I am waiting for another prog board from ali. I will be able to test in few weeks.
