Anybody have a linker script for the LPC1768?

I'm lost! Can't seem to find one. I'm modifying existing ones (LPC17xx) based on the memory in the 1768 and I can't get it to vector off and run code! I spent years working with the LPC2124 and LPC2138 and never had this problem! I developed entire UAV autopilots around these chips. In hindsight, I guess I had a good linker to start with because I never had to learn this part. Or reading on this stuff? I'm willing to RTFM.

Examples including Linker-Scripts and startup codes are in the package "lpc17xx.cmsis.driver.library.zip" available from nxp.com Please note that the examples for GNU might use some specials from the Codesourcery G++ Lite package (_start from library which seems to copy .data and init .bss before calling main()) and might not work with other precompiled packages of the GNU toolchain.

Well I got a hold of a similar download but instead it was named: "lpc17xx.cmsis.library.zip" I couldn't get it to work. I'm going to try what you pointed me to now.

This section in make.rules.environment should be pointing to the header files, but the compiler is still puking on that. FWLIB_DIR =$(BUILD_ROOT)/$(FWLIB) FWLIB_SRC_DIR =$(FWLIB_DIR)/source FWLIB_INC_DIR =$(FWLIB_DIR)/include I can go through and add full paths to the #includes to get past this, but I know that is not the right way. **** Build of configuration Debug for project CMSIS_gnu **** make all Building file: ../Examples/WDT/RESET/wdt_reset_test.c Invoking: ARM Windows GCC C Compiler arm-elf-gcc -O0 -Wall -Wa,-adhlns="Examples/WDT/RESET/wdt_reset_test.o.lst" -c -fmessage-length=0 -MMD -MP -MF"Examples/WDT/RESET/wdt_reset_test.d" -MT"Examples/WDT/RESET/wdt_reset_test.d" -mcpu=cortex-m3 -mthumb -g3 -gdwarf-2 -o"Examples/WDT/RESET/wdt_reset_test.o" "../Examples/WDT/RESET/wdt_reset_test.c" ../Examples/WDT/RESET/wdt_reset_test.c:19:25: error: lpc17xx_wdt.h: No such file or directory In file included from ../Examples/WDT/RESET/wdt_reset_test.c:20: ../Examples/WDT/RESET/lpc17xx_libcfg.h:23:23: error: lpc_types.h: No such file or directory In file included from ../Examples/WDT/RESET/wdt_reset_test.c:20: ../Examples/WDT/RESET/lpc17xx_libcfg.h:139: error: expected ')' before '*' token ../Examples/WDT/RESET/wdt_reset_test.c:21:28: error: lpc17xx_pinsel.h: No such file or directory ../Examples/WDT/RESET/wdt_reset_test.c:22:26: error: debug_frmwrk.h: No such file or directory ../Examples/WDT/RESET/wdt_reset_test.c:23:26: error: lpc17xx_gpio.h: No such file or directory ../Examples/WDT/RESET/wdt_reset_test.c:40: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'menu1' ../Examples/WDT/RESET/wdt_reset_test.c:52: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'info1' ../Examples/WDT/RESET/wdt_reset_test.c:53: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'info2' ../Examples/WDT/RESET/wdt_reset_test.c: In function 'c_entry': ../Examples/WDT/RESET/wdt_reset_test.c:70: warning: implicit declaration of function 'debug_frmwrk_init' ../Examples/WDT/RESET/wdt_reset_test.c:73: warning: implicit declaration of function '_DBG' ../Examples/WDT/RESET/wdt_reset_test.c:73: error: 'menu1' undeclared (first use in this function) ../Examples/WDT/RESET/wdt_reset_test.c:73: error: (Each undeclared identifier is reported only once ../Examples/WDT/RESET/wdt_reset_test.c:73: error: for each function it appears in.) ../Examples/WDT/RESET/wdt_reset_test.c:76: warning: implicit declaration of function 'WDT_ReadTimeOutFlag' ../Examples/WDT/RESET/wdt_reset_test.c:77: warning: implicit declaration of function '_DBG_' ../Examples/WDT/RESET/wdt_reset_test.c:77: error: 'info1' undeclared (first use in this function) ../Examples/WDT/RESET/wdt_reset_test.c:79: warning: implicit declaration of function 'WDT_ClrTimeOutFlag' ../Examples/WDT/RESET/wdt_reset_test.c:81: error: 'info2' undeclared (first use in this function) ../Examples/WDT/RESET/wdt_reset_test.c:85: warning: implicit declaration of function 'WDT_Init' ../Examples/WDT/RESET/wdt_reset_test.c:85: error: 'WDT_CLKSRC_IRC' undeclared (first use in this function) ../Examples/WDT/RESET/wdt_reset_test.c:85: error: 'WDT_MODE_RESET' undeclared (first use in this function) ../Examples/WDT/RESET/wdt_reset_test.c:87: warning: implicit declaration of function 'WDT_Start' ../Examples/WDT/RESET/wdt_reset_test.c: At top level: ../Examples/WDT/RESET/wdt_reset_test.c:108: error: expected ')' before '*' token make: *** [Examples/WDT/RESET/wdt_reset_test.o] Error 1

When I call make from the command line (but there is such a directory :(
):
