; @Title: Linux Demo for TRACE32 OS Awareness on the NEC NET1-TB Board
; @Description: 
;   This script is supposed to attach to a running Linux on NEC NE1-TB board. 
;   The Task Awareness + Debugger Address Translation are prepared as for the 
;   GSRD. After execution of this script the debugger is ready for Process, 
;   Kernel, optional Module and optional Library debugging.
;   It will NOT run on any other board, but may be used as a template
;   for others.
; @Keywords: awareness, NEC, RTOS
; @Board: NET1-TB
; @Chip: ARM11MPCORE

; Starting Linux example with TRACE32 and Hyperterminal:
; - Start TRACE32
; - Open Terminal,connect to serial port using the Honda adapter
; - 38400 baud, 8/N/1, no(!) handshake
; - Switch on the board
; - TRACE32: Start this script
