Hello!

To flash your Colibri iMX7 eMMC module with the images you built using Yocto, you can use the Toradex Easy Installer, which is the recommended tool for this purpose. Here’s a step-by-step guide to help you through the process:

Required Files

From your build output, you will typically need the following files:

  • U-Boot Bootloader: u-boot-colibri-imx7-emmc.imx
  • Kernel Image: zImage-colibri-imx7-emmc.bin
  • Device Tree Blob (DTB): Choose the appropriate .dtb file for your hardware setup, such as imx7d-colibri-emmc-eval-v3.dtb.
  • Root Filesystem: This is usually contained in a file like initramfs-ostree-torizon-image-colibri-imx7-emmc.cpio.gz.

Flashing Process

  1. Prepare the Toradex Easy Installer:

    • If not already installed, download the Toradex Easy Installer and load it onto your module. This can be done by booting the module into recovery mode and using a host PC to load the installer via USB.

  2. Create a Tezi-Compatible Image:

    • Organize the required files into a directory structure compatible with the Toradex Easy Installer. This includes creating a teziimage.json file that describes the image and its components.

  3. Load the Image:

    • Copy the prepared image directory to a USB drive or SD card.
    • Insert the USB drive or SD card into the module.

  4. Use the Toradex Easy Installer:

    • Boot the module with the Easy Installer.
    • The installer should detect the image on the USB drive or SD card.
    • Follow the on-screen instructions to flash the image onto the module.

  5. Verify Installation:

    • Once the flashing process is complete, reboot the module to ensure it boots correctly with the new image.

This process will install your custom-built image onto the Colibri iMX7 eMMC module, allowing you to run your Yocto-based system. Make sure to adjust the teziimage.json file to match your specific configuration and requirements.

I hope this helps! If you have any more questions, feel free to ask.
