Colibri iMX6DL 起動しないことがある

Colibri iMX6DLにて、起動動作が不安定で、起動しないことが多々あります。
起動しても5分程度でフリーズし、コマンドを入力できない状態になります。
その後、電源をOFF→ONしても起動しない状態です。30分くらい放置すると再び起動します。

Easyinstallerを使用し初期化しようとしましたが、以下のエラーが表示され、初期化できませんでした。
”Block Device ‘/dev/mmcblk0’ does not exist
The image has not been written completely. Please restart the process,
otherwise you might end up in a nonbootable system.”

不具合の原因はeMMCと考えていますが、2021/12に使用開始しているので経年劣化でNGといえるのか疑問です。
見解をお願い致します。

Hello,

I’m sorry to hear about the issues you’re experiencing with your Colibri iMX6DL module. The boot instability and freezing could indeed be related to the eMMC, especially given the error message from the Toradex Easy Installer. Here are some steps you can take to diagnose and potentially resolve the problem:

  1. Check Hardware Connections: Ensure that all connections to the module and carrier board are secure. Sometimes, loose connections can cause intermittent issues.

  2. Environmental Factors: Verify that the module is operating within its specified temperature range, as extreme conditions can affect performance.

  3. eMMC Health: While eMMC wear is possible, it typically depends on the number of write cycles. If your usage has been write-intensive, this could accelerate wear. However, under normal conditions, eMMC should last several years.

  4. Accessing eMMC via U-Boot: Since the Toradex Easy Installer cannot detect the eMMC, try accessing it through the U-Boot bootloader. You can attempt to erase the eMMC using U-Boot commands:

    • Interrupt the boot process to enter U-Boot.
    • Use commands to list and erase partitions as described in the Toradex documentation.
  5. Reinitialization: If you can successfully erase the eMMC via U-Boot, try reinitializing the module with a fresh image using the Toradex Easy Installer.

  6. Further Investigation: If the problem persists, consider other potential hardware issues or software bugs. Reviewing the module’s errata and known issues might provide additional insights.

By following these steps, you should be able to determine if the eMMC is the root cause and take appropriate action. If the issue continues, further hardware diagnostics might be necessary to rule out other potential causes.
