Problem with update esp-idf.

I cloned new version of ESP_IDF, but I can not build any project.
In eclipse error is like this:
esp-idf/tools/check_python_dependencies.py
The following Python requirements are not satisfied:
cryptography>=2.1.4
pyparsing>=2.0.3
Please refer to the Get Started section of the ESP-IDF Programming Guide for setting up the required packages.

And when I try to execute: python -m pip install --user -r $IDF_PATH/requirements.txt
I get this:
Command "C:/msys32/mingw32/bin/python.exe C:/msys32/mingw32/lib/python2.7/site-packages/pip install --ignore-installed --no-user --prefix .../appdata/local/temp/pip-build-env-sz21te/overlay --no-warn-script-location --no-binary :none: --only-binary :none: -i https://pypi.org/simple -- setuptools>=18.5 wheel "cffi>=1.8,!=1.11.3; python_implementation != 'PyPy'"" failed with error code 1 in None

What I hvae to do?

This should help:

Code: Select all

pacman -S mingw-w64-i686-python2-cryptography mingw-w64-i686-python2-pyparsing
If you still get the above error then it means that you have too old versions and have to update:

Code: Select all

pacman -Syu
Note that if pacman updates itself then you will have to update once again.

I downloaded new version of msys32 and toolchain and next I run command:
python -m pip install --user -r $IDF_PATH/requirements.txt
It done successfully but when I try to build old version of project I get this message:

I'm having a similar issue, when trying to compile the ulp example y have the next warning:

Done! You can now compile ESP-IDF projects.
Go to the project directory and run:

  idf.py build
As far as I understand the ulp assembler should be supported, what can I do?

Hi Palonso,

please check the content of your PATH *before* running export.sh. Maybe it already point to an old version of the ULP compiler.

Sorry, I don't get quite well what you mean.

I did a fresh install of the ESP IDF and I have that same warning, so I don't think that my PATH has an older version of the ulp compiler.

On the other hand the .profile file is clean (with the default code, etc.) and my .bashrc has the alias "get_idf" set as described on the installation guide.

Any idea?

Hi Palonso,

even if you use a fresh install of ESP-IDF still you can have some leftover from previous setup, for example if you used older ESP-IDF on the same computer at the time when the toolchain had to be installed manually and the PATH variable set.

Let me explain in more details.
The PATH variable contains a list of paths which are used to find the executable you are running. Let say you have executable X in two directories dir1 and dir2 and the content of PATH is "dir1;dir2". Then running X will be executed always from dir1 because that is earlier in the PATH variable.

The output of the export script says that
"Added the following directories to PATH: ...
/home/pablo/.espressif/tools/esp32ulp-elf/2.28.51-esp-20191205/esp32ulp-elf-binutils/bin" which seems to be right. However, if you have a path in your PATH variable pointing to a directory which contains an older "esp32ulp-elf-as" then it will be executed resulting in "WARNING: ULP assembler version is not supported. Expected to see version: 2.28.51-esp-20191205".

That is why I advise you to examine the content of your PATH and see if it doesn't point to a directory with the old toolchain.

It doesn't seem to point to an older version of the compiler, and all the ESP-IDF files are before any other directory in the PATH list.

Any idea? is there a way to manually "load" a compiler to the enviroment and compile the ulp code? how can compile the ulp on one side and then adding its *.elf file to the main program?
