Re: [Xen-users] Running Xen on ARM Juno r0

[N Jain <jain61@xxxxxxxxx>]

Hi Ian,

I tried again with the uefi which you sent but I am still getting CPU0 panic.

Now I don't have any difference between setup but not sure why I am still facing this issue ?

Can you please let me know what specific device tree nodes xen look for so I can convert dtb to dts and debug further ?

Thanks.

I got it with the firmware, which I got from

http://snapshots.linaro.org/member-builds/armlt-platforms-release/latest/juno-latest-oe-uefi.zip
Where it is SOFTWARE/juno.dtb but, as you can see in the images.txt I
provided (<1442848071.10338.102.camel@xxxxxxxxxx>) it is renamed to
board.dtb when it is written to the NOR flash.

NOR3UPDATE: AUTOÂ Â Â Â Â Â Â Â Â;Image Update:NONE/AUTO/FORCE
NOR3ADDRESS: 0x02000000Â Â Â Â Â ;Image Flash Address
NOR3FILE: \SOFTWARE\juno.dtb  Â;Image File Name
NOR3NAME: board.dtb       ;Specify target filename to preserve file
extension
NOR3LOAD: 00000000Â Â Â Â Â Â Â Â;Image Load Address
NOR3ENTRY: 00000000Â Â Â Â Â Â Â ;Image Entry Point

In fact this entry is even present in your own images.txt which you gave in
<CAOkOUeeLXLvujjZ7xOkhg6KndPWxKcG=47k-kxHq0LWU=3zw-A@xxxxxxxxxxxxxx>.

Ian.
