CubeIDE OpenSTLinux SDK Manager no SDKs available

[wincak]

I'm trying to setup CubeIDE for STM32MP1 but cannot make it to see the OpenSTLinux SDK.

Following this article:
https://wiki.st.com/stm32mpu/wiki/How_to_install_the_Yocto_Project_SDK_in_STM32CubeIDE

The popup window that should allow to download the SDK does not show up. Instead there is another one that opens the SDK manager directly. So I downloaded the SDK manually. However this SDK manager fails to recognize the SDK directory.

These two discussions seem to imply that entering path of the directory where SDKs are installed should be enough:
https://community.st.com/t5/stm32-mpus-products/openstlinux-sdk-manager-can-t-find-updated-sdk/m-p/568427

https://community.st.com/t5/stm32cubeide-mcus/stm32cubeide-cannot-find-openstlinux/m-p/621928

However in my case the "Available OpenSTLinux SDK:" window is always empty.

3 directories, 8 files

Clicking on "Apply" does nothing.

After clicking on "Apply and Close" this error shows up:

I have tried entering the SDK path directly, path of a parent folder, etc., even tried to remove the "stm32mp1-" prefix from the SDK's directory name to match exactly the name given in the error but there was no change.

There is no further information when I run CubeIDE from terminal and run into this error.

Since I eventually want to use a Yocto SDK I tried adding that as well. In this case clicking on apply results in a different error (which might or might not be related):

I'm using Kubuntu 24.04.2 and a new installation of CubeIDE Version: 1.18.1 (tried both Debian and generic installers) with a freshly created empty project.

What am I doing wrong?

Hi @wincak,

First you need to deploy the SDK with the script st-image-weston-openstlinux-weston-stm32mp1.rootfs-x86_64-toolchain-5.0.3-openstlinux-6.6-yocto-scarthgap-mpu-v24.11.06.sh and then point to the folder that was created.

here's the wiki page that explains how to deploy the SDK : https://wiki.st.com/stm32mpu/wiki/SDK_for_OpenSTLinux_distribution#SDK_installation

Grégory

Thank you for pointing out this embarassing oversight.

When I installed the toolchain to the default location proposed by the installation script (/opt/st/stm32mp1/...) and tried to use this toolchain in the SDK manager, the CubeIDE gives this error:

An internal error occurred during: "OpenSTLinux Lookup".
Cannot read the array length because "setupFiles" is null

Installing the toolchain to the home folder instead seems to fix this problem.
