Flowcode Support Board

I've been trying to install the ESP32 toolchain as described in "Flowcode ESP32 Toolchain Installation guide".
Used version 2.3 on a (genuine) Windows 7 PC.

The installation always get stuck on "checking certificates". This stays running for ever.
If I (after a few hours) click "next" the installation goes further but no sign of GIT or Python after the installation.

Any suggestions?

Your setup is showing Setup - ESP Tools 2.9
The official instructions show the download link and installing 2.3.
Latest is not always best and later versions have not been tested, therefore can't be supported via the Flowcode forums.
You will need to stick as close as possible to versions shown in the guide of all the different tools, e.g Python 3.7, ESP v4.1 or the nearest to it.

I downloaded the file in the path of the document and the name of the downloaded file is "esp-idf-tools-setup-2.3.exe"

I saw that too, but I guess that I downloaded the right file?

Martin you are brilliant,

Now I've downloaded the file from the Matrix website and I get a whole other screen when I execute the file.
Message to all: don't download the 2.3 version from the ESP link because this will lead you to version 2.9 (that is named 2.3).

I hope this may solve problems for other users.

Yes, You are indeed correct.
Don't download from ESP link, Download ESP Tool chain from here instead.
Are you up and running now?

Thanks medelec35!

Another issue that can be added to the ToDo list of Flowcode:

The name of the folder in which I store my Flowcode projects contains a "non-everyday character" (ASCII code 230).
When I send the project to the chip (ESP32_wroom32), I can see that there are errors in the name of the folder it's working with.
So "µ" is changed into "µ".

Not a big issue, but for centuries I've been storing my projects in this folder.

@Matrix Staff: please change the "ESP toolchain install guide". The link to the Expressif points to a wrong version of the ESP-IDF.

You are right and ESP themselves has changed the software the link points to.
This will be looked into, and the document will be changed.
We appreciate you bringing this to everyone's attention.

I've just tested compiling a Flowcode project saved in a folder called "testµ" and it compiles ok. This was using the AVR toolchain. So it looks like your issue could be specific to the ESP toolchain, which unfortunately is not in our control to change.

Thanks Steve, but this is just a minor problem.
The real problem is the link to the 2.3 version on the Expressif website, this downloads the 2.9 version..

I've edited the instructions now so they are a bit clearer and the first link is to the original file on the MatrixTSl server.

The second link is still there but now marked as experimental.
