Hi list,

I’m looking to run xen on a “Toradex i.MX95 19X19 TITAN EVK”. My u-boot output is

According to exchange with NXP, i know my current revision board support the linux kernel tag 6.6.3-1.0.0 ( Re: imx95 arm-scmi error on linux-imx tag lf-6.12.34-2.1.0 - NXP Community )

I follow https://www.nxp.com/docs/en/user-guide/UG10163.pdf (chapter 17.2 Xen Hypervisor) and NXP Documentation Portal (replacing LF_v6.12.34-2.1.0_images_IMX95.zip by LF_v6.6.3-1.0.0_images_IMX95.zip)

When i run the following commands

The xen image is not loaded properly…

Did i miss something?

Is it possible to run xen with my current hardware and kernel revision please?

Thanks. Regards.

Hi, I’m the Toradex AI Assistant.

I might make mistakes or occasionally get you wrong. Our support team will step in if needed.

I cannot provide specific guidance for running Xen on the “Toradex i.MX95 19X19 TITAN EVK” based on the available Toradex documentation. The documentation I have access to does not cover Xen hypervisor configuration or support for the iMX95 platform specifically.

However, I can help with some general observations based on your error message:

Error Analysis

The error “Failed to load ‘xen’” followed by “Bad Linux ARM64 Image magic!” suggests that either:

  • The Xen binary is not present in the expected location
  • The image format is incorrect or corrupted
  • U-Boot cannot properly identify the Xen hypervisor image

U-Boot Environment Variables

From the Toradex U-Boot documentation, you can verify and modify environment variables using standard U-Boot commands (1). The variables you’re setting (xenlinux_addr, dom0fdt_file, xenhyper_bootargs) appear to be NXP-specific rather than standard Toradex variables.

Device Tree Considerations

The device tree file imx95-19x19-titan-adv7535-ap1302.dtb you’re specifying should match your hardware configuration (2). Device trees are crucial for proper hardware initialization and driver loading (3).

Alternative Approach

For Toradex-supported virtualization and containerization solutions, I’d recommend exploring Torizon OS with its container-based approach, which provides isolation and resource management capabilities that might meet your virtualization requirements.

If you specifically need Xen hypervisor support, you may need to work directly with NXP’s documentation and support channels, as this appears to be an NXP-specific implementation rather than a Toradex-supported configuration.

Best regards, Toradex AI Assistant.
