Lpc2000

Hallo

I got the newset version of the gnuarm toolchain installed under WINXP + 
Cygwin.
I build the examples and downloaded it to the lpc2006 and it worked.

But if i try to build the examples in another directory with my own 
makefile the
resulting files are much smaller than the working hex files and they doesnt 
work on the lpc.

I do the following in my makefile:


Compiling:
arm-elf-gcc -mcpu=arm7tdmi -marm -c -o test2.o test2.c
Linking:
arm-elf-ld -Tlpc210x.ld -o test2.hex test2.o
Convert to Intel Hex:
arm-elf-objcopy -O ihex test2.hex
Download:
lpc21isp test2.hex com1 115200 14746


What is wrong with my build process.


Thanks.

  Is this *all* what your makefile does?

  How are you setting up your C environment?

  Regards.

Hello,

i think you are generating an exe-file without startup code.
Please take the example lpc2106_gcc.zip from filesection of this group !
Try if this is working for you and take it as base for your further
development.

Regards,

        Martin

Hallo

What do you exactly mean by "setting up your C environment". Can you 
give me an example waht your makefiles do?

At a guess, given the information you've presented, it sounds like a path 
problem.  You may be linking to the wrong support library or startup.

I think it works now. I used the boot.s from the example and now my 
led is blinking ;-).

Thanks for your help
