Re: [Xen-devel] Unable to boot Dom0 on Hikey

[Saeed Mirzamohammadi <saeed@xxxxxxx>]

Thanks for your feedback. Yes, I'm using "HiKey" that I recently bought. I tried RELEASE-4.9.0 and RELEASE-4.8.0 and RELEASE-4.7.3. None of them boots. There were little differences. Xen 4.8 printed one line more and stopped:

~~~~~~~~~~~

.......

(XEN) Freed 268kB init memory.

(XEN) Hardware Dom0 shutdown: rebooting machine

~~~~~~~~~~~

Xen 4.9 rebooted after it failed to boot.

Do you think the issue is with the Xen version?

This is how I build Xen:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
cd xen/xen
export CROSS_COMPILE=aarch64-linux-gnu-
export ARCH=arm64
export XEN_TARGET_ARCH=arm64
make defconfig
make -j8
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~`

Should I make specific config for HiKey?

And in this link: https://lists.gt.net/xen/devel/433472, they could boot the system by disabling the USB_DWC2 in the kernel. I tried modifying the .config file directly and disabling the ones related to USB_DWC2  (commenting the line out) but when I tried rebuilding the kernel it restarted generating the .config file. So I couldn't apply this comment.

And just to make sure, you are using HiKey not Hikey960. There is a big
difference between them and you can only buy Hikey960 nowadays.

That is a bit old. How about Xen 4.9?
