; Script arguments:

|
|
; DO lpc12xx [PREPAREONLY] [CPU=<cpu>]

|
; PREPAREONLY only declares flash but does not execute flash programming
|
|
; example
|
|
;
|
|
; CPU=<cpu> selects CPU derivative <cpu>
|

|

;
|
|
; CRP is invoked by programming a specific pattern in flash location

|

; Name Pattern Description
|
|
; --------------------------------------------------------------------------------
|
|
; NO_ISP 0x4E697370 Prevents sampling of pin PIO0_12 for entering ISP
|
|
; mode. PIO0_12 is available for other uses.
|
|
; CRP1 0x12345678 Access to chip via the JTAG pins is disabled.
|
|
; This mode allows partial flash update using the
|
|
; following ISP commands and restrictions:
|
|
; * Write to RAM command cannot access RAM below
|
|
; 0x10000300.
|
|
; * Copy RAM to flash command can not write to Sector 0.
|
|
; * Erase command can erase Sector 0 only when all
|
|
; sectors are selected for erase.
|
|
; * Compare command is disabled.
|
|
; * Read Memory command is disabled.
|
|
; This mode is useful when CRP is required and flash
|
|
; field updates are needed but all sectors can not
|
|
; be erased.
|
|
; CRP2 0x87654321 Access to chip via the JTAG pins is disabled. The
|
|
; following ISP commands are disabled:
|
|
; * Read Memory
|
|
; * Write to RAM
|
|
; * Go
|
|
; * Copy RAM to flash
|
|
; * Compare
|
|
; When CRP2 is enabled the ISP erase command only allows
|
|
; erasure of all user sectors.
|
|
; CRP3 0x43218765 Access to chip via the JTAG pins is disabled. ISP
|
|
; entry by pulling PIO0_12 LOW is disabled if a valid
|
|
; user code is present in flash sector 0.
|
|
; This mode effectively disables ISP override using
|
|
; PIO0_1 pin. It is up to the user's application to
|
|
; provide a flash update mechanism using IAP calls or
|
|
; call reinvoke ISP command to enable flash update via
|
|
; UART.
|
|
; Caution: If CRP3 is selected, no future factory
|
|
; testing can be performed on the device.
|
|
;
|
|
; RAM used by IAP command handler:
|
|
;
|
|
; Flash programming commands use the top 32 bytes of on-chip RAM.
|
|
; The maximum stack usage in the user allocated stack space is 128
|
|
; bytes and it grows downwards.
|
|
;
|
|
; HINTS:
|
|
;
|
|
; Flash clock has to match System Clock Frequency (CCLK).
|
|
; FLASH.CLocK.AUTO can be used for automatic flash clock measurement.
|
|
;
|
|
; Boot flash cannot be programmed or erased with builtin flash
|
|
; algorithm.
|
|
;
|
|
; Data has to be loaded to flash alignment to page boundaries.
|
|
;
|
|
; Vector table checksum generation is done by script, so that it
|
|
; can be used or switched off, as needed.
