espcoredump.py error

[23skidoo]

hello,

when analysing core dump file using espcoredump.py, with either the coredump saved to flash or b64 .dat file saved after UART print, espcoredump.py is giving the following error;

Which file or directory does the error relate to? thanks

I'm having the exact same issue.

I tried the espcoredump.py from IDF 3.3, 4.0 and 4.2 and with the same results.

I used an abort() call in code to generate a coredump .

Does the esp-idf folder need to be added to the python path? I don't have this folder in my python path currently:

Code: Select all

home@Droid5:~$ python -c "import sys; print(sys.path)"
['', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-x86_64-linux-gnu', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/home/home/.local/lib/python2.7/site-packages', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages/gtk-2.0']

There appears to be a few different ways to add/append a folder to the path.
