Xen project Mailing List

Hi all,

I'm trying to get Xen 4.4 running on my ODROID-XU device but I got stuck. I followed the Wiki and built a 3.13 kernel with the necessary xen options enabled and verified that it boots by itself. I built Xen from git and created a u-boot image as follows:

 mkimage -A arm -T kernel -a 0x40008000 -e 0x40008000 -C none -d "./xen/xen" xen-uImage

I tried a variety of u-boot configuration options found on the Wiki and the mailinglist, however, nothing seems to be working. The Wiki is not very consistent about the u-boot options either. This is the last config i tried, but nothing made a difference so far. I get no output on the console after u-boot.

setenv initrd_high "0xffffffff"
setenv fdt_high "0xffffffff"
setenv xen_addr_r 0x42000000
setenv dtb_addr_r 0x46000000
setenv kernel_addr_r 0x49000000
setenv ramdisk_addr_r 0x60000000
setenv xen_path /xen-uImage
setenv dtb_path /exynos5410-odroidxu.dtb
setenv kernel_path /uImage-xen-dom0
setenv ramdisk_path /uInitrd-xen-dom0

setenv bootargs 'sync_console console=tty1 console=ttySAC2,115200n8'
setenv dom0_bootargs "${bootrootfs} ${fb_control} fb_x_res=${fb_x_res} fb_y_res=${fb_y_res} vout=${vout} hdmi_phy_res=${hdmi_phy_res} led_blink=${led_blink}"

fatload mmc 0:1 ${dtb_addr_r} ${dtb_path};
fatload mmc 0:1 ${xen_addr_r} ${xen_path};

# When is this required?

fdt addr ${dtb_addr_r}
fdt resize

# What do these options do? Are these specific to the device or Xen or ..?

fdt set /chosen \#address-cells <1>
fdt set /chosen \#size-cells <1>

fdt mknod /chosen module@0

fatload mmc 0:1 ${kernel_addr_r} ${kernel_path};

# What is linux-zimage? My images are not in zImage format, does that matter?

fdt set /chosen/module@0 compatible "xen,linux-zimage" "xen,multiboot-module"
fdt set /chosen/module@0 reg <${kernel_addr_r} 0x${filesize} >
fdt set /chosen/module@0 bootargs "${dom0_bootargs}"

fatload mmc 0:1 ${ramdisk_addr_r} ${ramdisk_path};

setenv bootcmd "bootm ${xen_addr_r} ${ramdisk_addr_r}:${filesize} ${dtb_addr_r}"

The output is:

No output after that.

I'm a newbie to the ARM world and spent the last couple days reading everything related that I could get my hands on. Some help would be much appreciated!

Thanks.
