Guru Meditation Error: Core 1 panic’ed

[YourName]

Hello.

I have an ESP32 and use it with ESPHome and it first ran well. I updated its configuration several times with success. And suddenly it began to crash with :

What is happening ? Is my ESP broken ?

Thank you in advance, it's a bit panic here...

[ESP_Dazz]

Code: Select all

[17:24:01]Guru Meditation Error: Core  1 panic'ed (LoadProhibited). Exception was unhandled.

LoadProhibited means the CPU was trying to load from an illegal address in memory.

Code: Select all

[17:24:01]EXCVADDR: 0x00000008

The CPU was trying to read from memory address 0x00000008 which is definitely illegal. This could be caused either by a programming error (e.g. trying to read a null pointer), or by memory corruption (e.g. a valid pointer was overwritten by a stack overflow).

Judging from your backtrace, the illegal load happens somewhere on the stack of the loopTask. If you're application was working before, my guess would be a stack overflow somewhere in the loopTask (not sure how you would do that using ESPHome YAML configuration) or lowering your logger level configuration (will probably reduce stack usage). Alternatively, you could raise this issue at the ESPHome repo.

Thank you for answering.

I have two identical ESP32, one works well, the other gives this error backtrace.

How can I know the problematic ESP32 has not any hardware issue ? Is there a sort of self-test on ESP32 ?

[hdnguyen]

It looks like you set value for a string in an illegal way. Could you share your code snippets?

[YourName]

It is the ESPHome code. But I have 2 identical ESP32, from same factory, purchased together, and one works perfectly since weeks, the other refuses and gives the above error.

I get the same error trying to switch between 2 thingspeak channel updates. Honestly, it's my experience that on this chipset ....this just happens 60% of the time. I just don't get it. I'd get out of arduino IDE but it's a senior design project and I port my code again in time.
