Need Help Flashing Python-Compatible Yocto Image on Colibri i.MX6ULL with Aster Carrier Board

Technical Support
1

Hello,

I’m currently working with a Colibri i.MX6ULL module mounted on an Aster Carrier Board, and I need to flash a Yocto-based image that is configured to support Python. I’m looking for advice or a guide on how to properly configure and flash this image. Here are some specific points where I could use guidance:

  1. Building the Image: What steps should I follow to include Python in my Yocto image? Are there specific layers or recipes in the Toradex meta layers that I should include to get Python support?
  2. Flashing the Image: Once I have my image built, what is the recommended procedure to flash it onto the Colibri i.MX6ULL using the Aster Carrier Board? Are there tools or commands provided by Toradex that I should use?
  3. Verification: After flashing, how can I verify that Python is properly installed and functioning as expected on the device?
  4. Potential Issues: Are there common pitfalls or issues that I should be aware of during this process? For example, issues related to hardware compatibility, software dependencies, or configurations?

I appreciate any documentation, tips, or personal experiences you can share regarding this process, especially from those who have worked with Python on the Colibri i.MX6ULL and Aster setup.

The Multimedia Reference Image 6.6 already includes Python 3 (version 3.8.18).

If you wish to build your own custom image, please refer to this document.

To flash an existing or your custom image, please use the Toradex Easy Installer. You will need to put the module in recovery mode and load the installer over USB OTG.

You can verify if the flashed image includes Python by running the python3 command via shell, which is accessible either over debug UART or by SSH.

I have a custom image I made with bitbake. How do I use the easy installer to get my own image file on the device?

Follow this instructions please.

My image fails to init. Where can I find how to correctly structure the local.conf to include the packages I want? All I see regarding this is EXTRA_IMAGE_FEATURES and PACKAGE_CLASSES. Where do I find a list of available options for these?

I recommend building a reference image as is and loading it onto the module to ensure that your setup is functioning properly. Once confirmed, you can then add extra layers. For Python, you can follow the guidelines in this article.
