Lpc2000

I've used keil uvision3 demo for some test lpc2106, i like it, but
the cost of running version is out of my budget (vendors ask about 
1700eu.+tax), so i ask me if someone can help me in building the
arm compiler/linker gnu for windows.xp (i hate pc-windows ,but, for 
now, i must live with them), ok - in any way - greats thanks at 
anyone!
enjoy life!

Bill Gatliff have on his Homepage a good instruction to build the gcc 
for a ARM. The link is : 
http://www.billgatliff.com/articles/gnu/gnu-arm7t.html/index.html

For the lpc2106 , use as target "arm-thumb-elf"  and if you ready
to Compile you need the switch  "-mcpu=arm7tdmi"  for the gcc.

 sincerely yours

Keil uses GNU, don't they? You could just use the GNU tools from the command
line when their IDE etc. expires.

uVision supports integration either with the GNUPro tools [which Keil 
supplies] or with the ARM tools, if you have them.

The IDE does not expire, or at least the version I was given doesn't. 
The limitation on it is that the debugger can only handle 16K of code, 
and you are not permitted to ship commercial apps that have been 
debugged with the debugger.

I am still trying to get a positive answer on whether it is permissible 
to ship commercial apps that just happened to be compiled with the demo 
IDE.

(BTW: Hi, Leon. I'm getting "heavily" involved in the LPC2129, as part 
of a book project. Expect to see me around here a lot :).

I suppose we can put up with that. 8-)

Have you actually got hold of any '2129s?

Hi Leon,

> Have you actually got hold of any '2129s?

I have one on the desk next to me. However, there are apparently only 
four other EVBs of this model in the United States, so supply may be a 
little thin right now. I'm also not sure how secret it is at the 
moment. All the datasheets I have are festooned with dire warnings, 
predictions of seven plagues, photographs of four horsemen, etc.

Keil uses GNUpro which does not expire and can be used without
having to purchase it.  HOWEVER, the version of GNUpro that Keil
is shipping was built with uClibc (not newlib).  uClibc is LGPL
licensed, so be VERY cautious about creating and shipping product
built with it.  For open source work it may do just fine.  For
commercial work, you may be required to make at least the object
code available to your customers on demand.

  You can help us test the distro if you use it ;^)

I built the toolchain last night in anticipation of producing code
for chips that are anticipated shortly. :)  The default instructions
didn't work for me, so I made a few changes.  I also made some
changes to customize the generated tools for the lpc21xx family.

For the final gcc build, I did:
../gcc-3.3.2/configure --target=$TARGET --prefix=$PREFIX --with-gnu-as --with-gnu-ld --disable-shared --with-newlib --disable-threads --with-cpu=arm7tdmi --enable-target-optspace --enable-languages=c --with-headers

The only important part was the --enable-languages=c, I think.  It was
having trouble building the C++ standard library--why, I'm not sure.
The other stuff just looks like it would be handy.

--disable-shared -- well, there's no OS on there to provide shared
libraries, so no point in building in support for them.

--disable-threads -- I'm not building a multithreading executive

--with-newlib -- it's not obvious if this was needed, but it seemed save
to add as I was using newlib.

--with-cpu=arm7tdmi -- this just tells the compiler that the default target
for which to produce code is the arm7tdmi, so we never have to specify it on
the command line when we build code.

--enable-target-optspace -- I have no idea if this makes any difference
at all, but it might.  It tells the compiler to optimize for space on
generated code.  Seems handy for these little chips.

--enable-languages=c -- tells it to just build the C compiler.  It's all
I plan to program in--aside from assembly.  I used this to keep it from
building C++ and the problems that was having.

--with-headers -- this tells it to build with a different set of system
headers.  It should get the path correctly from the --prefix option.

Oh, I think you can speed up the build by adding a '--enable-languages=c'
to the bootstrap build of the compiler as I don't think the other ones
are used.

I was doing this on a Linux host.  Running RH9 with all current updates.

Good luck!

Cheers,
David

Hi,  
the GNU chain is available prebuilt at the following location:
 
http://www.ariusdsp.com/gnuarm/index.html
 
 
this was posted to comp.sys.arm recently. Hope this helps.
