I think you're asking how to cross-compile. That is, you want to
compile C and C++ code on your Windows PC and then get it running on
your ARM board. This is quite a large topic, but in essence:
* Get cygwin installed and ensure you have all the relevant GCC tools.
This will give you a base development environment (but at this stage
only for *Windows* executables.
* Now grab and install the Cross-compiler toolkit from
ftp://ftp.embeddedarm.com/ts-arm-linux-cd/cross-toolchains/crosstool-cygwin-gcc-3.3.4-glibc-2.3.2.tar.bz2
* At this stage you have some C and C++ compilers (most likely in
C:\cygwin\opt\crosstool\gcc-3.3.4-glibc-2.3.2\arm-unknown-linux-gnu\arm-unknown-linux-gnu\bin)
which are capable of compiling C and C++ code into ARM assembly which
the development board can run.
To start with something *very* simple, make a hellow.c file and put
#include <stdio.h>
int main(int argc, char*argv[])
{
printf("hello world\n");
return 0;
}
in it. Compile this with the cross-compiler on your windows machine:
C:\cygwin\opt\crosstool\gcc-3.3.4-glibc-2.3.2\arm-unknown-linux-gnu\arm-unknown-linux-gnu\bin\gcc
-o hellow hellow.c
this will make an ARM executable called 'hellow'. You must now copy
this to the embedded system. If you're only using HyperTerminal (as
your post suggests) you must bring up the hyperterm window, type 'rz'
in it and then browse to the 'hellow' file. This should copy 'hellow'
to the ARM board.
Now, on the arm board you must mark the 'hellow' file as being an
executable: type 'chmod a+x hellow'. Now you can finally run it with
'./hellow' on the ARM board. You should see 'hello world' printed out
(yay!).
As for getting the LCD working, that's much more of a chore, though
it's possible to compile the example code and use that pretty much
as-is. Alternatively you could try using the LCDmod kernel driver
with my patch (http://xania.org/article.php/lcd_driver) though I'd
suggest that's a bit more complex than you need at the moment.
For developing larger applications on the ARM box I suggest you get a
decently-set up linux setup for your main PC and use the cross tools
there. I've also had quite a lot of success with ScratchBox
(http://xania.org/article.php/buildingbuilding) which makes for easy
cross-development. I'm now myself back to developing on a windows
machine and the cross-compiler, using various Samba and NFS-root
tricks to build directly onto the embedded box's file system.
I hope something in this rather long post is helpful to you! :)
