[Xen-users] Bringing up xen on omap5432

 I am trying to bring up xen on omap5432 and running into some issues.
I pretty much followed the following.

Build Xen:

# git clone git://xenbits.xen.org/xen.git

# cd xen

# make dist-xen XEN_TARGET_ARCH=arm32 CROSS_COMPILE=arm-linux-gnueabihf- CONFIG_EARLY_PRINTK=omap5432

Create uImage for Xen:

Â# mkimage -A arm -T kernel -a 0x90000000 -e 0x90000000 -C none -d "xen/xen" xen-uImage

2)Create a dtb file using the following command

Âmake ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- omap5-uevm.dtb

3)Build Uboot following instructions at


But when I try to boot I am running into an undefined instruction exception.

U-Boot# bootm $xen_addr_r - $dtb_addr_r

On a side note how do I do an objdump of the xen and u-boot code to get to the instruction that is causing the crash?

Any instruction on how to add debug instrumentation to u-boot would also help.
