Hello
I am a new to XEN and am trying to boot it on J6 EVM.
Followed many different sources of information, and finally found the closest kin to my current board ..
http://wiki.xenproject.org/wiki/Xen_ARM_with_Virtualization_Extensions/OMAP5432_uEVM
I have U-Boot, both Xen and Linux cross compiled using Linaro for arm, and device tree DRA7xx.
I cannot see anything beyond triggering to launch Xen Kernel from u-boot.
Here is the log:

I can give you specific information, once you have an idea of what I am doing is not a grave mistake.
