; @Title: Flash declaration for Zhixin Z20K148M internal flash
|
|
; @Description:
|
|
; Script arguments:
|
|
; DO z20k148m [PREPAREONLY] [CPU=<cpu>] [DUALPORT=<0|1>]
|
|
; PREPAREONLY only declares flash but does not execute flash programming
|
|
; CPU=<cpu> selects CPU derivative <cpu>
|
|
; DUALPORT=<0|1> use dual port memory access, default 0
|
|
;
|
|
; Example:
|
|
; DO ~~/demo/arm/flash/z20k148m PREPAREONLY
|
|
; Note:
|
|
; This file must NOT be modified.
|
|
; This file is intended to stay within TRACE32 installation.
|
|
; Usage examples are available in the ~~/demo/arm/hardware/... subdirectories.
