I tried to follow the installation procedure for the master branch for the ESP32 IDF. But when I tried the Hello_world example I got the following errors. I am on Windows 10 and I followed the instructions for the windows install.

I cloned the espressif/esp-idf repository today. Why do I get the above warnings? What should I do to get the correct environment installed?

It says right there

run "pacman -Syu" if your package database is older and run twice

I ran it once and I got the errors I posted above. Since this was a new install, from a current git, why would I expect that it would be older?

But thank you for your help. It did get me to retry and I did get further. After playing snakes and ladders for a while I finally did get the two .py packages installed. It does compile now. But I still have the first problem, the old toolchain. I cloned the current ESP-IDF, should this not give me an up to date toolchain? No I guess. Then how do I go about updating it.

Or am I wrong in thinking that the ESP-IDF is the toolchain in question?

In addition to the old toolchain problem I get an error when trying to access the COM port that my ESP32 is connected to. I can start up a serial terminal program and access the ESP32 on COM11. I close the terminal program and try to program the compiled Hello_World program and I get the above errors. Any ideas on what I am doing wrong? Did I specify COM11 incorrectly?

Esp-idf is the sdk
Msys2 is the environment
Xtensa-esp32-elf is the toolchain

https://docs.espressif.com/projects/esp ... nvironment

The port is just COM11 without any path

The "toolchain" is the compiler (gcc), linked (ld) and related GNU compiler tools ("binutils"). It's something used by the ESP-IDF SDK. It's not bundled inside the ESP-IDF directory itself.

Code: Select all

WARNING: Toolchain version is not supported: crosstool-ng-1.22.0-73-ge28a011

The error message suggests that the toolchain version you have is old, compared to what the ESP-IDF version you have is expecting.

- To update the installation you have, you can follow the link WiFive posted. Alternatively:

- If you installed MSYS2 by downloading the "all-in-one" zip file, check that you downloaded the latest version of this zip file. Instructions here. Maybe you were following installation steps for an older version of ESP-IDF than the one you have? If you downloaded an older .zip, maybe the easiest thing to do is to download the newer one and replace the C:\MSYS2 directory.

I wanted to use the most current git so I followed the instructions Getting Started Guide for the latest (master branch) ESP-IDF version. https://docs.espressif.com/projects/esp ... index.html

I will try again when I get home tonight.
