Re: [Xen-users] Booting dom0 on OMAP5432 board

[Konstantin Belov <konstantin.belov@xxxxxxxxx>]

Hello Chen,
 Exactly. My build cmds:

$ make dist-xen XEN_TARGET_ARCH=arm32
CROSS_COMPILE=arm-none-linux-gnueabi- CONFIG_EARLY_PRINTK=omap5432
$ mkimage -A arm -T kernel -a 0x80200000 -e 0x80200000 -C none -d
"xen/xen" xen-uImage

Output in console:
## Booting kernel from Legacy Image at 90000000 ...
   Image Name:
   Image Type:   ARM Linux Kernel Image (uncompressed)
   Data Size:    721724 Bytes = 704.8 KiB
   Load Address: 80200000
   Entry Point:  80200000
   Verifying Checksum ... OK
## Flattened Device Tree blob at 825f0000
