"No Toolchain found for Target ESP32C3" / No compilers installed

[BrianP]

I spent several hours trying to install the ESP-IDF under Windows 10. I followed the documentation exactly, except the documentation differs from what I actually see. I have tried online and offline installers. When the installation finishes I get a menu which says Completing the ESP-IDF Tools Setup Wizard and allows me to chose Run ESP-IDF Eclipse and/or Register the ESP-IDF tools

2021-05-20 11_19_26-Standard Setup of Toolchain for Windows - ESP32 - — ESP-IDF Programming Guide la.png (154.42 KiB) Viewed 7156 times

I do not see the menu described in the documentation. I have tried running the powershell and cmd as per the menu. When I ran those commands I got variations of

"Not using an unsupported version of tool cmake found in PATH: 3.17.3."

I modified my path so that the path to the IDF was first and those errors went away. I was then able to compile hello_world for esp-32 and esp-32s2. If I attempt

idf.py set-target esp32c3 (https://docs.espressif.com/projects/esp ... .html#id11 )

I get

Usage: C:\Users\bjpic\Desktop\esp-idf-5\tools\idf.py set-target [OPTIONS] {esp32|esp32s2}
Try 'C:\Users\bjpic\Desktop\esp-idf-5\tools\idf.py set-target --help' for help.

Error: Invalid value for '{esp32|esp32s2}': 'esp32c3' is not one of 'esp32', 'esp32s2'.

Running ESP-IDF Eclipse yields similar results except for esp32c3 I get
Build not configured correctly

and for esp32/esp32s2 it compiles, however, my include files and all the assorted things in them are flagged as unresolved. I consider this a separate issue.

Having done a search of my PC, there are no compilers for ESP32-C3 present.

Can somebody please help.

Thanks.

Hi,

I looks you are using the ESP-IDF v4.2 (only supports ESP32 and ESP32-S2).
To support ESP32-C3, you'll need to upgrade to v4.3 or v4.4 (master).

[BrianP]

Geez. I followed exactly the instructions here https://docs.espressif.com/projects/esp ... -variables

You'd think the instructions for ESP32-C3 would be correct.

Thanks!

I'll give it a try.

[BrianP]

Now when I try to run install.bat I get the error

ERROR: This script was called from a virtual environment, can not create a virtual environment again


I am perplexed by the multitude of conflicting and non-working installation instructions.

Can anybody point me to a (working) step by step ESP-IDF installation instruction which supports ESP32-C3?

Thanks

[ESP_Minatel]

You can use git clone to get the latest version on master and then to use the install script manually.

Code: Select all

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

Code: Select all

cd %userprofile%\esp\esp-idf
install.bat

We have another approach but we are still preparing a detailed guide on how to use: https://github.com/espressif/idf-env

[BrianP]

Yes, I know. This is what happens

Note the error



EDIT I am trying again "clean"
EDIT I get exactly the same result.

Note that

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

Installs into esp-idf, not esp/esp-idf, unless you run it from esp. Nonetheless,
cd %userprofile%\esp\esp-idf
install.bat

yields the same error

[ESP_Minatel]

The ERROR: This script was called from a virtual environment, can not create a virtual environment again means that you are trying to run the install from a virtual environment, created by the shortcuts after the installation process.

Can you try to use a new Console/PowerShell window? Not the ones created by ESP-IDF Installer.

[BrianP]

That is what I have been doing.

<windows key> R cmd

cd ing to the directory and running install.bat.

Bizarrely, when I installed the idf with the installer (i.e. the wrong one it told me to do with the ESP32-C3 instructions it did not complain but when I do it from git it does.

The git install does not appear to install python. but an earlier ESP-IDF install installed 3.8.7

C:\Users\bjpic\esp\esp-idf>python

Type "help", "copyright", "credits" or "license" for more information.

Note that I am running on Windows 64, not Win32.

[ESP_Minatel]

I'm trying to help you, but I'm running Linux now and I cant test using the same scenario as yours.

Can you, kindly, try to add this command after the install .exe file from the command line?

For the v4.3

Code: Select all

esp-idf-tools-setup-x.x.exe /IDFVERSION=[v4.3]

For master (v4.4)

Code: Select all

esp-idf-tools-setup-x.x.exe /IDFVERSION=[master]

You can define the version manually by using the argument /IDFVERSION=[VERSION].

This is documented at our GitHub: https://github.com/espressif/idf-installer

[BrianP]

Thank you for the reply!

There is no program esp-idf-tools-setup-x.x.exe or of that general form on my system. I had versions of esp-idf-tools-setup-online-2.8, tools-setup-offline-2.8, etc., so I assumed that's what you meant.

When I run esp-idf-tools-setup-offline-2.8 /IDFVERSION=[v4.3] it offers me the option of setting up v4.2.1 or v4.1.1, exactly as per previous runs so I did not proceed.

However, I did happen upon this webpage https://github.com/espressif/idf-installer/releases and decided to try esp-idf-tools-setup-online-2.9-beta-05.exe.

This ran OK though I had to run install and export manually afterwards.

I can now run this
idf.py set-target esp32c3

and
idf.py build

successfully!

I have also flashed hello_world but I get garbage out of the serial port so I have to guess the proper baud rate.

Thanks for your help!
