abort() was called at PC 0x... on core 1

Hi,
How can I find where in the source program is the line that generates the error?

CORRUPT HEAP: Bad tail at 0x3ffb8695. Expected 0xbaad5678 got 0xbaad560d
abort() was called at PC 0x400832fd on core 1
Backtrace: 0x40084e80:0x3ffb1af0 ...

It depends. In esp-idf, it's easiest to use 'idf.py monitor' as your terminal program, as it automagically decodes those addresses. In Arduino, your best bet is EspExceptionDecoder.

ESP_Sprite many, many thanks !

Of corse, overflow

len=512;
buf = (char *)malloc(len);
..
buf[len]=0x00; <--
...
free(buf); <-- that is the line reported by tools EspExceptionDecoder (interesting).

[ESP_Sprite]

Nice that you found it. buf[len]=0 doesn't give an error as there still is valid memory one byte past the end of the array, and C doesn't do runtime bound checks, so it happily will write there. However, one byte past the bounds check is a magic word used by the memory allocator, and the write corrupts this word. free() will check this word, note it's corrupted and abort.

Hi.

I've used this code to join in the helium LoRaWAN. I ended up with the following error. I am not sure what to do.

Hi, i am using o heltec stick lite with the ESP32_LoRaWAN library on PlatiformIO, but my code is crashing. The message returned is this:

abort() was called at PC 0x40082132 on core 1

I tried to use the EspExceptionDecoder, but the line that is crashing is at MCU.init, when i try to access the code i only get the .h code and not the .cpp code. When i use the same library and same board at the Arduino IDE everything run fine...

Any one has some idea what is hapaning???
