Hi Chen,

My previous issue was resolved when i used hi6220-hikey.dtb from this source: https://github.com/kuscsik/device-linaro-hikey-kernel. When I download linux kernel, there doesn't seems to contain hi6220-hikey.dtb.

But now it got stuck while loading Dom0 and below are log traces:

It just hang there after the last line above.
I have looked into those messages " d0v3: vGICD: unhandled word write 0xffffffff to ICACTIVER0" and linux kernel already taking care to ignore it. Therefore, I believe this is not contributing to there hang here. Any idea on this issue?

Thanks,
Kamenee

You should compile kernel first. Please follow the "Getting Started" page on 96boards

Hi Chen,

I have tried to flash UEFI in my board with latest one but still facing
the same issue. Regarding to use dtb file from kernel source, I couldnt
find hi6220-hikey.dtb in my source kernel. i am downloading my kernel
source from
here: https://github.com/96boards/linux/tree/android-hikey-linaro-4.1

I only could find hi6220-hikey.dts file in the kernel source. Therefore
download from other github but which is correct one that i need to use?
In case, I am using incorrect kernel source, pls point to me to correct
one if you aware of?

Thanks,
Kamenee

The xen.cfg file seems fine to me. I suggest you try to use the dtb
file compiled from the kernel source and update UEFI bootloader on
hikey board to the latest version.

hope this could help.

I have already pass hi6220-key.dtb in my xen.cfg:

options=console=dtuart dom0_mem=512M dom0_max_vcpus=4 conswitch=x
dtuart=/smb/uart@f7113000
kernel=Image console=hvc0 root=/dev/mmcblk1p4 rootwait rw
dtb=hi6220-hikey.dtb

I download the hi6220-hikey.dtb from this site:
https://android.googlesource.com/device/linaro/hikey-kernel/+/f117fa12746b59aa0a1a4d6335145e58935c422b/hi6220-hikey.dtb

Firstly, I build kernel using the command below:

make -j24 Image hi6220-hikey.dtb

I placed hikey6220-hikey.dtb in linux directory level. I also
copied the
dtb into sd before booting up. Please correct me if my steps are
wrong.

I am following this wiki (http://wiki.xen.org/wiki/HiKey
<http://wiki.xen.org/wiki/HiKey>) to
setup xen in hikey. I am not sure what could cause this
issue
here. Appreciate all of you input and advice here.

Thanks,
