esp8266 panics

[tablatronix]

I have started getting panics on esp8266, and have not been able to reproduce or find the cause.

Anyone have seen this before?

Panic /Users/.../.platformio/packages/framework-arduinoespressif8266/cores/esp8266/core_esp8266_main.cpp:103 __yield

Why would a yield() cause a panic or wdt?
If i remove it crash stops..
I am calling in setup, not an interrupt or anything like that..

adafruit_SPITFT.cpp:1204

#if defined(ESP8266)
        do {
            uint32_t pixelsThisPass = len;
            if(pixelsThisPass > 50000) pixelsThisPass = 50000;
            len -= pixelsThisPass;
            // yield(); // Periodic yield() on long fills
            while(pixelsThisPass--) {
                hwspi._spi->write(hi);
                hwspi._spi->write(lo);
            }
        } while(len);

Now my hardware wdt resets, no idea what is causing that, there is no anyc callbacks in my code , could gfx be causing that?

[ladyada]

🤷‍♀ you can try previous versions of GFX to see if its due to new code

[tablatronix]

hmm

I rolled back esp and gfx as far as I could without having to rollback Adafruit_ILI9341 also

no change

at a loss now, Ill see what esp8266 know about this

Maybe make sure you have the latest version of ESP8266 BSP? I know they pushed some breaking changes out recently.

[tablatronix]

What is BSP ? I am using platformio, and have tried staging, stable, and 2.0.4

[makermelissa]

Board Support Package. Ok, I'm not very familiar with platformio, so maybe it's set up differently than Arduino.

[tablatronix]

I never could figure this out, It seemed to be some kind memory issue, and gfx write was getting stuck in a large or infinite loop it seemed. Going to close for now.
