See my reply to the other thread, but yes this could very well be caused by increasing the heap size too far.
I optimized my code and was able to reduce the heap size back to the stock value. I'm still seeing errors similar to this sometimes though. I'm trying to eliminate causes, but it is taking a long time since the issue is intermittent. I was using a USB hub to repl into the ESP, but now I'm connected directly to my PC. I now also have a desktop PSU (Rigol DP832) powering the unit in parallel with the USB to eliminate bad power as the cause. I feel like I'm just stabbing in the dark though since I can't decipher the error message. I've tried to correlate the addresses in the error to lines in the firmware.map file and a plain text version of the firmware.elf file, but I'm not seeing anything helpful.
Is there any info out there on how to interpret WDT error messages? Just knowing exactly
what the terms "load", "len", "room", "tail", and "chksum" were referring to would be very helpful.
