Boot loop, Guru Meditation Error

[BengtStavdal]

The firmware compiles without issues. But immidiately after the upload I get an error with a boot loop:

[21:38:21]Rebooting...

I have tried the firmware and the example .yaml on two separate, different brand esp32 boards with same results.

I wonder if you could help me to get this working?

Hi,
I'm not most experienced with these boards but with the little experience I have core panic usually means some kind of hardware misconfiguration (or failure).

However I see warning that
[21:38:21][W][app:022]: Component already registered! (0x3ffb8d1c)
Do you have App registration multiple times in your config?

Otherwise it is not easy to help without access to board and config...

You could also try to remove all sensors from config file and see if it is then booting...

Br,
Erkka

I wondered that warning myself. Not sure what's causing it though because I'm using the provided example config. The only difference is naturally the wifi settings.

I did some investigation myself and it seems that the LoadProhibited would suggest that the program is trying to read something from an illegal memory address of EXCVADDR: 0x00000030.

I also tried to temporarily comment out the whole UponorThermostat -class in knx_rf.h, just to check if it would boot correctly. And to my surprise it did boot.

I was also wondering if there has been some breaking changes in the SmartRC-CC1101-Driver-Lib or in newer esphome libraries after you made the last commit
