The issue you’re experiencing with the Colibri iMX7 V1.1A module not booting correctly with the same image used for the V1.1D module could be due to several factors. Here are some potential areas to investigate:

  1. Device Tree Compatibility: The error message indicates a problem with the Flattened Device Tree (FDT). Ensure that the device tree blob (DTB) file is compatible with both module versions. The image.json file specifies the same DTB for both product IDs 0033 and 0041, but you should verify that the DTB is indeed suitable for the V1.1A module.

  2. Module Identification: The boot log for the V1.1A module shows “Toradex UNKNOWN MODULE V1.1A”. This suggests that the module is not being correctly identified. Check if there are any differences in the module’s identification process or if there are updates needed in the U-Boot environment or the image configuration to properly recognize the V1.1A module.

  3. U-Boot Environment: Since the environment is loaded from NAND, ensure that the U-Boot environment variables are correctly set for the V1.1A module. There might be differences in the environment that need to be addressed.

  4. Image Configuration: Review the image.json configuration to ensure that all necessary files and settings are correctly specified for both module versions. Pay special attention to the supported_product_ids and ensure that all necessary files are included and correctly referenced.

  5. Hardware Differences: Although the modules are expected to be compatible, there might be subtle hardware differences that require specific configurations or updates in the software stack.

  6. Software Updates: Ensure that you are using the latest version of the Toradex Easy Installer and the BSP that supports both module versions. There might be updates or patches that address compatibility issues.

If these suggestions do not resolve the issue, consider reaching out to Toradex technical support for further assistance, as they may have more specific insights or updates regarding compatibility between these module versions.
