It looks like you’re encountering a kernel panic when trying to boot the Xen hypervisor on your Apalis iMX8QM module. The error message “Unable to copy the kernel in the hwdom memory” suggests that there might be an issue with the memory configuration for the Xen hypervisor.
Here are a few steps you can take to troubleshoot and potentially resolve this issue:
-
Memory Configuration:
- Ensure that the memory regions allocated for Xen and Dom0 are correctly configured. You might need to adjust the memory settings in your Xen configuration file.
- Verify that the memory regions do not overlap and that there is enough memory allocated for both the hypervisor and the Dom0 kernel.
-
Kernel and Device Tree:
- Make sure that the kernel and device tree you are using are compatible with Xen. Sometimes, specific patches or configurations are required for the kernel to work correctly with Xen.
- Check if there are any specific configurations or patches needed for the Apalis iMX8QM when running Xen.
-
Bootloader Configuration:
- Ensure that U-Boot is correctly configured to load the Xen hypervisor and the Dom0 kernel. Double-check the boot commands and memory addresses used in U-Boot.
- You might need to adjust the boot arguments passed to the Xen hypervisor to ensure it can correctly locate and load the Dom0 kernel.
-
Xen Configuration:
- Review the Xen configuration files to ensure that all settings are correct for your hardware. Pay special attention to the memory settings and any hardware-specific configurations.
- Check the Xen documentation for any additional settings or parameters that might be required for the i.MX8QM platform.
-
Debugging:
- Enable additional debugging in Xen to get more detailed logs. This might help pinpoint the exact cause of the memory allocation failure.
- You can also try running Xen in a more verbose mode to get more information about what is happening during the boot process.
-
Consult Documentation and Support:
- Review the Toradex and Xen documentation for any known issues or additional configuration steps required for the i.MX8QM platform.
- If the issue persists, consider reaching out to Toradex support or the Xen community for further assistance.
Given the complexity of running a hypervisor like Xen, it might take some trial and error to get everything configured correctly. If you continue to face issues, providing detailed logs and configuration files to support channels can help in diagnosing the problem more effectively.
