Hi guys !
I am a rookie in gcc.So please help me out.
I have arm-elf-gcc 4.1.1 installed on Ubuntu and I have to cross
compile for ARM7TDMI-S core based LPC2368 processor.
I have the C runtime file crt0.S, the startup.S,processor's header
file and I have also modified the ROM.ld.
So, what I remember , the process will be :
1. Convert C source code to object file.
2. Link all the object files to create an executable.
3. Convert the executable to intel hex format.
But I am unable to link as I have a few doubts.
Question 1 : crt0.S is not getting converted to crt0.o and startup.s
to startup.o. How to do it ?
Question 2 : How to link ROM.ld with other files ?
Best bet is just to start with a project that is already working. You could
start with the LPC2368/Eclipse demo in the FreeRTOS.org download which has a
standard makefile (although I have only tested on Windoze so you may find
some case problems in the include paths). Alternatively look in the files
section of the LPC2000 Yahoo group.
