== Xen instruction setup for dra7xx-evm board == |
|||
= Introduction = |
|||
The purpose of this tutorial is to run Xen on dra7xx-evm board. |
|||
Some commands are to be executed on the Linux development host, some on the Linux target and some on the u-boot (bootloader) prompt. The following conventions are used to distinguish the commands on a host and on the target: |
|||
* '''host $''' <this command is to be executed on the host> |
|||
* '''target #''' <this command is to be executed on the target> |
|||
* '''u-boot :>''' <this command is to be executed on the u-boot prompt> |
