ESP32 Forum

I upgraded my IDF as follows:

1. a rename on my old esp-idf folder (to easily revert)
2. `git clone -b v3.2.2 --recursive https://github.com/espressif/esp-idf.git` to get the latest IDF per docs (see https://docs.espressif.com/projects/esp ... et-started)

Now `esp_ota_mark_app_valid_cancel_rollback()` (and others) from `esp_ota_ops.h` was no longer found. So:

3. I downloaded the IDF as a .zip from https://github.com/espressif/esp-idf and inspected `esp_ota_ops.h` (also available online as https://github.com/espressif/esp-idf/bl ... _ota_ops.h).

Conclusion: these are different files, see attachments (smaller file is from `git clone`)

This should be impossible, right?

The zip you downloaded was master (v4.0) branch but you cloned tag v3.2.2

You can find a zip file for IDF v3.2.2 here, near the bottom of the page:
https://github.com/espressif/esp-idf/releases/v3.2.2

(Note that if you get IDF via the automatic "Download" links that GitHub generates then builds won't succeed, as these GitHub-generated zip files don't include any submodules. For each release we make a zip file that include the submodules and attach it to the release page.)

Thanks for the replies.

Well, as stated, I followed the instructions in the getting started section on the page I linked to, which now (as an apparently direct consequence of my question) suddenly (and without comment here redirects to https://www.espressif.com/en/support/download/documents.

As an exercise I found a new page, https://docs.espressif.com/projects/esp ... t-started/ (which swaps "stable" for "latest"), saying:

The simplest way to do the update is to delete the existing esp-idf folder and clone it again, as if performing the initial installation described in Step 2. Get ESP-IDF.

Which results in:
My PC is busy doing this. Don't know what version this will get me (stable? latest? dev?). How do I check which IDF I am currently running? The answer is:
Note that when I search for 'esp32 idf releases', the top page is https://github.com/espressif/esp-idf/releases, whose title suggests all releases will be listed. Yet it is only v3.2.2.. I don't know how I got to the IDF 4.0 .zip, I probably search for the esp_ota_ops.h, found a different file and followed the trail.

So git clone terminated and then I got an error: "No rule to make target 'check_python_dependencies', needed by 'all'."

Decoding the error message vomit I find it says to run (as I have no pacman):

C:/msys32/mingw32/bin/python.exe -m pip install --user -r C:/msys32/home/user/esp/esp-idf/requirements.txt

To install "click".

That went down without a hitch so I guess I'm ready to run again!

Or, more likely, busy fixing up paths etc.

Now I'm instructed to update the toolchain, so I found: https://www.esp32.com/viewtopic.php?t=7400, which deals with the v2 update, but the links no longer work.

Then I found https://docs.espressif.com/projects/esp ... setup.html, not quite an update tutorial, but downloading the esp-idf-tools-setup-2.0.exe now.

Googling for updates of the toolchain leads me to number 3 from the results, which is named "Updating ESP-IDF tools on Windows — ESP-IDF Programming Guide", link: https://docs.espressif.com/projects/esp ... pdate.html. But that page is a Page Not Found page, consistently without CSS.

No other search results, so that leave me with the .exe and the probability the pain isn't over yet.

Well, the .exe doesn't seem to know anything about (my existing) MSYS32, and wishes to install in some user folder, so I aborted it.

For now.

So I guess I'm stuck. Again.

What does this .exe do?? The linking page says "To quickly setup the toolchain and other tools in standard way, using the ESP-IDF Tools installer, proceed to section Standard Setup of Toolchain for Windows".

The page itself (https://docs.espressif.com/projects/esp ... setup.html) says "ESP-IDF requires some prerequisite tools to be installed so you can build firmware for the ESP32. The prerequisite tools include Python, Git, cross-compilers, menuconfig tool, CMake and Ninja build tools."

But it goes on to install the IDF itself, which is not what it is supposed to do.

Nevertheless it seems like a dream come true. It's the new Cmake thing? But no word about how it might clobber existing installs.

So, what do I do now? Dump my current "legacy MSYS32 environment"?


The current compiler stops at:
Seems like "game over".

Reverted everything to my previous IDF, and that's that.
