I'm trying to boot Xen on Hikey but Dom0 doesn't boot after Xen! I can boot the linux individually with startup.sh. This works fine but when I try to boot xen (typing 4 and then xen), I get a couple of Xen messages and when it tries to boot Dom0 it fails and it stops there.These are the last messages:

(XEN) Loading kernel from boot module @ 000000007a029000

My Xen version is: 4.7.0.rc4 and my dom0 is: android-hikey-linaro-4.1. I tried earlier Xen version but no difference.

This is my xen.cfg:
options=dom0_mem=512M dom0_max_vcpus=4 conswitch=x console=dtuart
kernel=Image console=hvc0 root=/dev/mmcblk0p9 rootwait rw 3

and my startup.nsh:
Image dtb=hi6220-hikey.dtb console=ttyAMA3,115200 root=/dev/mmcblk0p9 rootwait rw efi=noruntime

I've checked out the thread here or others: https://lists.gt.net/xen/devel/433472 but I have passed the dtb file in the xen.cfg and still Dom0 doesn't boot.

Any help is greatly appreciated. 

Thanks a lot,
