;
;	Linux Demo for TRACE32 multitask debugger
;
;	This batchfile demonstrates the use of 
;	the Multitask-Debugger for Linux 
;
;   The example is generated for the evb297520v2fpga board using an ICD. 
;   It will NOT run on any other board, but may be used as a template for 
;   others.
;   Linux is downloaded to the board via ICD.

;            this script can only be used on NO jtag chain mode
