Response to Apalis iMX8QM WB IT Revision Compatibility

Based on the information available, I need to clarify a few important points about your situation:

Image Compatibility Between Revisions

Generally, the same BSP image should work across hardware revisions of the same module family. However, the specific revision change from 00671100 to 00671101 and any hardware-level differences between these revisions are not detailed in the available documentation.

Concerns About Your Current BSP Version

You’re using BSP 6.4.0-devel from August 2023, which is a development build rather than a production release. According to Toradex’s support strategy, you should be using stable quarterly or monthly releases for production development(1).

The current supported BSP versions for Apalis iMX8 include:

  • BSP 7.x (Yocto Scarthgap 5.0 LTS) - Latest(1)
  • BSP 6.x (Yocto Kirkstone 4.0 LTS) - Latest(1)

Your development tag from 2023 is outdated and may not include important fixes and updates that have been released since then.

Recommendations

  1. Update to a stable release: I strongly recommend updating to BSP 6.x or 7.x quarterly release rather than using a development tag from 2023. This will ensure you have the latest hardware support, bug fixes, and stability improvements(2)(3)(4).

  2. Hardware revision information: To get specific details about the differences between product numbers 00671100 and 00671101, you should use the tdx-info command on your modules or contact Toradex technical support directly, as hardware revision details aren’t fully documented in the sources available.

  3. Troubleshooting the faulty board: The intermittent issues you’re experiencing (RTC, file persistence, touchscreen) suggest either a hardware defect or a compatibility issue with your older BSP version. Testing with a current stable BSP release would help isolate whether this is a software or hardware issue.

Next Steps

  • Rebuild your image using a stable BSP 6.x or 7.x release
  • Test both modules with the updated image
  • If issues persist with one module after using a stable BSP, it’s likely a hardware defect

For specific hardware revision compatibility questions, I recommend visiting the Toradex Community or GitHub for additional support.
