|
===========
|
|
|
|
Introduction
|
|
------------
|
|
|
|
If the ESP crash the Exception Cause will be shown and the current stack will be dumped.
|
|
|
|
Example:
|
|
|
|
::
|
|
|
|
Exception (0): epc1=0x402103f4 epc2=0x00000000 epc3=0x00000000 excvaddr=0x00000000 depc=0x00000000

|
sp: 3ffffc10 end: 3fffffb0 offset: 01a0

|
|
The first number after ``Exception`` gives the cause of the reset. a
|
|
full ist of all causes can be found :doc:`here <../exception_causes>`

Decode
|
|
~~~~~~
|

It's possible to decode the Stack to readable information. For more info see the `Esp Exception Decoder <https://github.com/me-no-dev/EspExceptionDecoder>`__ tool.
