The port of Xen hypervisor on OMAP5 is already uptreamed. You should be able
to build it directly from the git repo. The only problem is that the omap
kernel has its only data structure for device description. Thus, you need to
disable the corresponding UART port that has been used by Xen serial in the
kernel tree (only disable it in FDT is not enough).

Hi Chen,

would you mind if I refresh the wiki with other information that could help to setup the boot process for the uEvm? I'm making some order in my notes and I would like to share them (e.g., adding CONFIG_ARCH_VIRT for the domU, how to boot domU, the userspace, how to setup u-boot specific for the board, etc).

By the way, another question: did you experience any failure of the FTDI chip on the uEvm? Mine is completely dead and the plug shows evidence of oxidation.

Best regards,
-Francesco

Never mind. Please just do it.

Haven’t noticed that before.
