|
|
; @Description:
|
|
; Synopsis:
|
|
;
|
|
; do ~~/demo/arm/flash/lm4f120 [<cpu>] [PREPAREONLY]
|

;
|
|
; Description:
|
|
;
|
|
; Script arguments are not case sensitive.
|
|
;
|
|
; <cpu>
|
|
; is the CPU name argument out of the table listed below. If debug
|
|
; connection is not already established CPU name argument is used for
|
|
; CPU selection. Without CPU name argument and no LM4F120 CPU is
|
|
; selected the script is using default CPU selection LM4F122H5QD.
|
|
;
|
|
; PREPAREONLY only declares flash but does not execute flash programming
|
|
;
|
|
; Example:
|
|
;
|
|
; do ~~/demo/arm/flash/lm4f120 LM4F120B2QR PREPAREONLY
