; @Title: Script for flashing Motorola MAC71x5 internal flash
|
|
;
|
|
; @Description:
|
|
; mac71x5 [unsecure | unlock]
|
|
;
|
|
; Motorola MAC71x5 internal flash. Core is ARM7TDMI-S.
|
|
; - MAC7105
|
|
; - MAC7115
|
|
; - MAC7125
|
|
; - MAC7135
|
|
;
|
|
; 768 kByte Program Flash address is depending on Operation mode.
|
|
; Expanded: 0x20000000--0x200bffff
|
|
; Single Chip: 0x00000000--0x000bffff
|
|
; Program interface: 0xfc100000--0xfc1bffff
|
|
; 32 kByte Data Flash at 0xfe000000--0xfe007fff
|
|
; 40 kByte RAM at 0x40000000--0x40009fff
|
|
;
|
|
; Optional argument unsecure is used to a unsecure a secured chip.
|
|
;
|
|
; Optional argument unlock is used to a reset LOCK bit of CFMMCR register.
|
|
;
|
|
; HINTS:
|
|
; Security word only can be written by a explicit data set to that
|
|
; location, for example "Data.Set 0xfc100414 %Long 0x80000000".
|
|
; All other operations do not allow securing the device. The two security
|
|
; bits are forced to unsecure value.
|
|
;
|
|
; Program and data flash have same unit number in flash declaration because
|
|
; mass erase does erase program and data flash.
