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:
## Booting kernel from Legacy Image at 42000000 ...

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.
