; @Title: NetBSD Demo for TRACE32 OS Awareness on Marvell DB88F5281 Board
; @Description: 
;   
;   This batchfile demonstrates the use of the OS Awareness for NetBSD
;   
;   The example is generated for a Marvell DB88F5281 board using an ICD.
;   It will NOT run on any other board, but may be used as a template
;   for others.
;   
;   NetBSD will be downloaded via ICD.
;
