Hi All,
Well I am tearing my hair out on this one and hoping someone can help.
I have a MCB2300 board that I have verified using Keil Realview
compiler - I can successfully compile and run the Blinky program.
I want to move to GCC so I installed winARM and downloaded the test
programs from the Files section on this group, but am unable to get the
programs to work. It compiles fine from the command line via make and
also within the Keil IDE but running them via FlashMagic does not work.
I have verified that FlashMagic is functioning as expected by
downloading the realview generated blinky prog.
I suspect I am having problems with the startup files (CRT0), would
someone please point me to a working blinky program for the MCB2300
using gcc with the startup files and also a confirmed hex file so I can
figure out what I am screwing up?
Thanks a ton
Jay

Shroffja,
U dont need startup file for WinARM.
U have to make Makefile and then compile..
U can try any example pgm mentioned in WinARM example codes.
It gets compiled and executed nicely.

The files section has a project from sahi_ono for the MCB2300 that
compiles fine but I cannot seem to get it to work.
The LPC23XX folder has a GNU project but compiling it results in the

Actually, you definately DO need that!!! There is no requirement that
it be named startup.s or CRT0.s, or whatever, but the function
performed by such a code file is definately required. The minimum
function of such a code file is to set up the exception vector table,
set up the required stacks, and perform RAM initialization before any
C code runs. There are a few other things that might be done in the
startup file, but the minimum functions are required for the C code to
even run properly. The last action performed in the startup file is a
jump to C's main().

Your linker script needs to define the above.

And you are missing the newlib stubs. As I recall WinARM uses newlib-lpc
to provide these. You can use that or provide a similar set of stubs.

Hi Jay,
Thats true, As I have LPC2148, I never seen whether LPC2300 examples are there or not.
I'm sorry I was wrong for startup.s file, definately u dont need that but there are two files required for linking.
one is *RAM.ld and other one *ROM.ld
I think project for KEIL does not work directly on WinARM,
both need different set of files other than source code.

Hi Ravi,
Don't you need the CRT0.s file? That is what I was referring to as
the startup file...
Anyway's what examples within winARM are you referring to it seems
most examples are for the 21xx series?
Thanks
