Hi,

Im trying to use espcoredump.py under macOS to read an exported dump file, the command I use on terminal is:
python3 /Users/user/esp/esp-idf/components/espcoredump/espcoredump.py info_corefile --core CoreDump-coredump.bin --core-format raw project.elf

However Im greeted with the following error message:

Code: Select all

Traceback (most recent call last):
  File "/Users/user/esp/esp-idf/components/espcoredump/espcoredump.py", line 16, in <module>
    from corefile.loader import ESPCoreDumpFileLoader, ESPCoreDumpFlashLoader
  File "/Users/user/esp/esp-idf/components/espcoredump/corefile/loader.py", line 34, in <module>
    PARTTOOL_PY = os.path.join(IDF_PATH, 'components', 'partition_table', 'parttool.py')
  File "/usr/local/Cellar/python@3.9/3.9.5/Frameworks/Python.framework/Versions/3.9/lib/python3.9/posixpath.py", line 76, in join
    a = os.fspath(a)
TypeError: expected str, bytes or os.PathLike object, not NoneType

Due to my limited knowledge on python and associated stuff, I'm unable to figure out why this is happening.

Im using visual code with ESP IDF extension and everything works fine and compiles, monitor works, erasing and flashing works, but this isn't.

Alright, I somehow got this fixed by resetting the env variable of esp idf, now im getting another issue:

Hi jojojijijojo,

The "/usr/local/lib/python3.9/site-packages" part of the backtrace indicates that you are using "python3" outside of ESP-IDF environment. Please use "python" from the mentioned environment - where you are running "idf.py build" as well. I don't use vscode but I assume this should be set up properly in a terminal inside vscode.

Thank you @ESP-Roland, that did the trick.
