; -------------------------------------------------------------------------------- ; @Title: Example for flash declaration of NXP LPC13xx internal flash. ; ; @Description: ; Script arguments: ; ; DO lpc13xx [PREPAREONLY] [CPU=] ; ; PREPAREONLY only declares flash but does not execute flash programming ; example ; ; CPU= selects CPU derivative ; ; Example: ; ; DO ~~/demo/arm/flash/lpc13xx CPU=LPC1347 PREPAREONLY ; ; List of LPC13xx derivatives and their configuration: ; ; CPU-Type FlashSize EEPromSize RamSize ; [kB] [kB] [kB] ; -------------------------------------------------------------------------------- ; LPC1311 8. - 2. ; LPC1313 32. - 8. ; LPC1315 32. 2. 8. ; LPC1316 48. 4. 8. ; LPC1317 64. 4. 8. ; LPC1342 16. - 4. ; LPC1343 32. - 8. ; LPC1345 32. 2. 8. ; LPC1346 48. 4. 8. ; LPC1347 64. 4. 8. ; ; Code Read Protection (CRP): ; ; CRP is invoked by programming a specific pattern in flash location ; at 0x000002FC. ; ; Name Pattern Description ; -------------------------------------------------------------------------------- ; NO_ISP 0x4E697370 Prevents sampling of pin PIO0_1 for entering ISP mode. ; PIO0_1 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. Since compare command is disabled in case of ; partial updates the secondary loader should implement ; checksum mechanism to verify the integrity of the flash. ; 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_1 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 UART0. ; 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. ; ; @Author: WRD ; @Copyright: (C) 1989-2019 Lauterbach GmbH, licensed for use with TRACE32(R) only ; @Chip: LPC13* ; -------------------------------------------------------------------------------- ; $Rev: 7616 $ ; $Id: lpc13xx.cmm 7616 2019-11-08 07:18:24Z bschroefel $ LOCAL ¶meters ¶m_prepareonly ENTRY %LINE ¶meters ¶m_prepareonly=(STRing.SCAN(STRing.UPpeR("¶meters"),"PREPAREONLY",0)!=-1) LOCAL ¶m_cpu IF VERSION.BUILD()>=29755. ¶m_cpu=STRing.SCANAndExtract(STRing.UPpeR("¶meters"),"CPU=","") ELSE PRINT "Argument CPU= ignored because Trace32 software is too old" ; ------------------------------------------------------------------------------ ; Start debugging IF SYStem.MODE()<5 ( SYStem.RESet IF "¶m_cpu"!="" SYStem.CPU ¶m_cpu IF !CPUIS(LPC13*) ( IF VERSION.BUILD()>=37389.
