Should not be, there is many things printed by Xen before it is tryin= g
to boot dom0, and it would say that it can not find a dom0.

All right, I've been able to reproduce the behaviour. Are you starting<= br> Xen using the u-boot command "go"? Because this does not work wit= h me.
It gave me some headache sometime ago. The command that works is "boot= m
$xen_addr -"
So, I'm curious, how do you start Xen on the board?

Here is what env I have on u-boot:
ipaddr=3D10.y.y.y
ipconfig=3D10.y.y.y
kernel_addr_r=3D0x40007000
serverip=3D10.x.x.x
tftp_path=3D10.x.x.x:pxelinux.cfg

bootcmd_load_linux=3Dtftpboot 0x40007000 10.80.3.61:pxelinux.cfg/linux-zIma= ge
boot_xen=3Drun bootcmd_load_linux; tftpboot $xen_addr_r
$tftp_path/xen-uImage; bootm $xen_addr_r -
bootcmd=3Drun boot_xen

with 10.y.y.y the ip addr of the board and 10.x.x.x the ip of a tftp
server (or PXE server).

By the way, I've pushed a new branch: arndale-2013-02-13 which fix few<= br> things.

This is the branch I've be= en using so far, I have been monitoring the repository for updates too and = this still seems to be the latest right?
=A0

This should make you pass the "turning on paging" step.

I'm still stuck at this step. Here is my environement:

Hi,

I was wondering if anyone else is f= acing the same issue. I've copied Anthony's PXE setup as well but w= ithout result. Using PXE or just sdcards and fatload both end up freezing a= t Xen start-up with the same "=A0*- Turning on paging -* " messag= e. Anthony you mentioned you previously had the same problem, maybe you cou= ld give me some more pointers on how to fix it?

Thx,
Sander

Yes, I've got a patch for it:

Should not be, there is many thing= s printed by Xen before it is trying
to boot dom0, and it would say that it can not find a dom0.

All right, I've been able to reproduce the behaviour. Are you starting<= br> Xen using the u-boot command "go"? Because this does not work wit= h me.
It gave me some headache sometime ago. The command that works is "boot= m
$xen_addr -"
So, I'm curious, how do you start Xen on the board?

Here is what env I have on u-boot:
ipaddr=3D10.y.y.y
ipconfig=3D10.y.y.y
kernel_addr_r=3D0x40007000
serverip=3D10.x.x.x
tftp_path=3D10.x.x.x:pxelinux.cfg
usbethaddr=3D00:40:5c:26:0a:5b
ethaddr=3D00:40:5c:26:0a:5b
xen_addr_r=3D0x50000000
bootcmd_load_linux=3Dtftpboot 0x40007000 10.80.3.61:pxelinux.cfg/linux-zIma= ge
boot_xen=3Drun bootcmd_load_linux; tftpboot $xen_addr_r
$tftp_path/xen-uImage; bootm $xen_addr_r -
bootcmd=3Drun boot_xen

with 10.y.y.y the ip addr of the board and 10.x.x.x the ip of a tftp
server (or PXE server).

By the way, I've pushed a new branch: arndale-2013-02-13 which fix few<= br> things.

<= span style=3D"font-family:arial,sans-serif;font-size:13.333333969116211px">= This is the branch I've been using so far, I have been monitoring the r= epository for updates too and this still seems to be the latest right?
=A0

This should make you pass the "turning on paging" step.

I'm still stuck at this step. Here is my environement:

ARNDALE5250 # pri

Two other questions;=A0

If not, can I see the progress somewh= ere ( notes? ) or can you tell me what the current problems are?
=A0=A0

After that, you will probably need few patches for Linux. I'll push the= m
later.

Have fun,

However, dom0 does not boot yet and i am also very interested in Anthony's patches for the dom0 kernel. Besides applying Anthony's patch i did the following: First of all xen needs to be compiled with a dtb file.

Second Xen expects a cortex-a15 GIC, you need to patch the device tree for this: diff --git a/arch/arm/boot/dts/exynos5250.dtsi b/arch/arm/boot/dts/exynos5250.dtsi index 6e6c7d1..afc5c3c 100644 --- a/arch/arm/boot/dts/exynos5250.dtsi +++ b/arch/arm/boot/dts/exynos5250.dtsi @@ -33,11 +33,16 @@ gsc3 = &gsc_3; }; - gic:interrupt-controller@10481000 { - compatible = "arm,cortex-a9-gic"; + gic: interrupt-controller@10481000 { + compatible = "arm,cortex-a15-gic", "arm,cortex-a9-gic"; #interrupt-cells = <3>; + #address-cells = <0>; interrupt-controller; - reg = <0x10481000 0x1000>, <0x10482000 0x2000>; + reg = <0x10481000 0x1000>, + <0x10482000 0x1000>, + <0x10484000 0x2000>, + <0x10486000 0x2000>; + interrupts = <1 9 0xf04>; }; combiner:interrupt-controller@10440000 { Third i disabled CONFIG_ARM_APPENDED_DTB in the dom0. I am unsure if this is necessary. I also applied this little hack to make the kernel accept my device tree, but the kernel still panics further in the boot process.
