Hi,

I am trying to flash a SOM with my easy installer image that was created with torizon core builder.

When I connect to the SOM I am required to enter the device’s model and serial number which I have never been asked to do before.

After selecting my image I am greeted with the following message

Any help would be greatly appreciated.

Hello! Thank you for reaching out with your question.

From your description, it sounds like when flashing your SoM with a custom Easy Installer image created by TorizonCore Builder, you are unexpectedly prompted for the device’s model and serial number, and you see an error message after selecting your image. Unfortunately, I can’t read the text in the attached screenshot, but I can guide you based on common scenarios and best practices.

1. Device Model and Serial Number Prompt

Typically, the Toradex Easy Installer will prompt for device details only if the device information is missing or if the image requires it for installation. This can happen if:

  • The internal storage was wiped, reset, or is missing device-specific information.
  • There is a mismatch between your image and the connected hardware (e.g., wrong SoM model).
  • The image.json is missing or incorrectly configured.

2. Error on Image Selection

Common reasons for installation failure include:

  • The image was not created for your specific SoM.
  • There are mistakes in your image.json file.
  • The image does not have proper compatibility tags.
  • The image format is corrupted or incomplete.

Recommendations

  1. Check image.json
    Open the image.json file inside your image directory and verify:

  2. Verify the Image Was Built for Your SoM
    If the image was built using torizoncore-builder, confirm the SoM model matches your hardware. You can adjust this using the customize and build commands:

  3. Recreate the Image if Needed
    If you spot issues in the steps above, it’s often helpful to rebuild the image with careful attention to SoM selection and configuration.

  4. Internal eMMC State
    If you formatted or erased the eMMC, sometimes device info stored in U-Boot environment is lost. This can trigger prompts for device model and serial number. These should be entered accurately when prompted to ensure subsequent installations work correctly.

  5. Try Official Reference Image
    As a test, download an official reference image for your SoM from Toradex and flash it using Easy Installer. This helps verify if the issue is related to your custom image or a broader problem with the device:

Next Steps:

  • Please review the text contents of your image.json and ensure the product ID matches your SoM.
  • If possible, copy and paste the exact error message you see after selecting the image for further targeted assistance.
  • If the device info prompt appears, enter the correct model and serial number as indicated on your SoM label.

Let me know if you need help interpreting your image.json, or if you’d like further step-by-step instructions.

Best regards,
Toradex AI Assistant.
