ESP32 Get started install ESP-IDF on Windows

[chromebin]

I am posting this for future reference. In the reply I document the solution I arrived at.

I am trying to install a dev environment for the ESP32. I am at the step 'Get ESP-IDF' at page http://esp-idf.readthedocs.io/en/latest ... et-esp-idf

This step asks me to run:

Code: Select all

mkdir -p ~/esp
git clone --recursive https://github.com/espressif/esp-idf.git

But that fails with this message:

Code: Select all

user@DINV005 MINGW32 ~/esp/hello_world
$ git clone --recursive https://github.com/espressif/esp-idf.git
Cloning into 'esp-idf'...
fatal: unable to access 'https://github.com/espressif/esp-idf.git/': Failed to connect to github.com port 443: Connection timed out

`git` simply doesn't seem to work. `wget` also doesn't work. `wget` works on very few sites.

When I go to github and download the zip, extract it to ~/esp/esp-idf, and do `make menuconfig` it doesn't work, seems to require a .git folder. I get a .git folder if I run the `git clone` above and kill it. `make menuconfig` now runs but at some point it deletes all of the `esp-idf` folder (its way of saying "f*** you") and the final command fails..

Summary: I found no way to make the install work work in MSYS2 on Windows 10, using https://dl.espressif.com/dl/esp32_win32 ... 180110.zip.

Looking at the error messages, I see:

Failed to connect to github.com port 443: Connection timed out

This is indicative of a fundamental networking problem. What the git command wants to do is make a network connection to the Github server, access the named project and download it's directory structure to your local PC file system. However, if your PC can't form a network connection to Github ... that would be the end of the story.

Perhaps github.com was transiently down. Try it again and see what happens. Perhaps there is a firewall or some other mechanism preventing access to that location. For example, in some businesses, they prevent access to github to prevent open source code making its way into the environment. Perhaps there is some configuration error in your "Linux on Windows wrapper".

Try and "ping github.com" and see if it responds.

Sometimes i got the same error message:

Code: Select all

fatal: unable to access 'https://github.com/espressif/esp-idf.git/': Failed to connect to github.com port 443: Connection timed out

but its enough to repeat git command or restart interface connection on linux ubuntu in VBox.

I was just getting ready to post this same problem when I saw this post last minute.
I am having the same issue.

Mike@DESKTOP-QPDOB55 MINGW32 ~/esp
$ git clone --recursive https://github.com/espressif/esp-idf.git
Cloning into 'esp-idf'...

Which is weird because I did all these same steps yesterday morning and worked great, Today I wanted to document the steps, and deleted everything to start over and I ran into this issue.

This is the reply I intended to post immediately, but the original message got lost in moderation

The solution basically sidesteps the `git clone` command in MSYS2. Instead execute it in Windows:

- make sure the command works (`git` is installed) in Windows. I use `Git version 2.16` from the "Git Development Community".

- Open `cmd.exe`: Win+R then type "cmd.exe"

- goto the `~/esp` folder from step http://esp-idf.readthedocs.io/en/latest ... et-esp-idf

- execute `git clone --recursive https://github.com/espressif/esp-idf.git`

If some components failed to checkout:

- goto the `~/esp/esp-idf` folder

- execute `git submodule update --init`

Now the next steps should work inside the C:\msys32\mingw32.exe shell (`make menuconfig` and `make flash`).

The exact same steps worked just fine the next morning. So all is good.
