[Xen-devel] Unable to boot Dom0 on Hikey

[Saeed Mirzamohammadi <saeed@xxxxxxx>]

Hi,

I'm following instructions on https://wiki.xenproject.org/wiki/HiKey and https://github.com/Jeeppler/xen-note/blob/master/arm64/hikey/hikey-xen-centos.md.

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:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

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
dtuart=/smb/uart@f7113000
kernel=Image console=hvc0 root=/dev/mmcblk0p9 rootwait rw 3

dtb=hi6220-hikey.dtb

and my startup.nsh:

FS0:

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,
