Possible causes:

Stack overflow
Stack corruption
String concatenation
Dynamic allocation

Current Solution:

Fail-safe implemented by Ritesh watchdog timer

Root Cause Analysis Req.

Next Steps

Memory Map using the avr obj dump command @ritesh007garg avr-objdump -t project.elf
Manual code review to check for best practices @aravinda-tworks
Logging from display Module on P3-b @sudo-goatboy @Beep-boop-sneep-snoop

k-aravinda commented 4 years ago

@aravinda-tworks to analyse the Memory map and add inputs. @ritesh007garg to add freeMemory() impl in Error Handling. This indicates the free memory on stack.
