Hi guys,

I am getting erros when I tried to compile the ARM7_LPC2368_Eclipse demo using
arm-none-eabi (from Codesourcery).
They appear to be "linker" related, because all the files compiled ok.

First one:

c:/program files/codesourcery/sourcery g++ lite/bin/../lib/gcc/arm-none-eabi/4.3.2/../../../../arm-none-eabi/bin/ld.exe: error: no memory region specified for loadable section `.ARM.exidx'

I tried to solve it (or at least, make the code compile) adding the following lines to the lpc2368.ld file (I found googling around):

/* .ARM.exidx is sorted, so has to go in its own output section. */
__exidx_start = .;
.ARM.exidx :
{
*(.ARM.exidx* .gnu.linkonce.armexidx.*)
} >ram
__exidx_end = .;

I have no idea if this is ok, but at least I dont get this error anymore...

But, now I got the following errors:

c:/program files/codesourcery/sourcery g++ lite/bin/../lib/gcc/arm-none-eabi/4.3.2/../../../../arm-none-eabi/lib/thumb\libc.a(lib_a-sbrkr.o): In function `_sbrk_r':

readr.c:(.text+0x10): undefined reference to `_read'

I am guessing it´s library related because of printf or something like it... What do I have to include explicitely ?

On the error messages, there´s references to libc.a , I tried to explicitely define -lc (no result). However in the demo projetct there is no explicit referente to any library.

Any sugestions?

THanks!

Try compiling with Yagarto. See www.Yagarto.de.

Dear Sergio,

The Yagarto tools should do it. I have the lpc2368 Eclipse demo compiling with Eclipse (Europe) and Yagarto. Check the tutorial on http://www.freertos.org/Eclipse.html for installing/configuring Eclipse.

OpenOSD might be usefull: http://openocd.berlios.de/web/.

Have fun,
Bart

Thank you guys,

I will try it, although the link for download in sourceforge is broken (yagarto). I managed to download the file googling around, although it´s not too safe to do it...

Thanks again,
Sergio P. Sider

Hi all,

I have followed the instructions to install Eclipse for testing the ARM7_LPC2368_Eclipse demo. But I have problem with the project's compilation:

**** Build of configuration Default for project RTOSDemo ****


(Exec error:Launching failed)

I would like to know if I have to install some other additional tool or setting for compiling the project without error? Please help me. Thanks.

Check that the GCC compiler is in your path.

Open a command prompt and type "arm-elf-gcc", you should get a message saying something like "no input file specified". If you get a message saying arm-elf-gcc is not a known program then you need to add the YAGARTO/bin directory to your PATH environment variable.

Next in the command prompt try typing "make". Does it recognise that command?

Regards.

Hi Richard,

It means that I have to install YAGATO as well? Anything else? Now I've just installed and configured Eclipse on my PC.

Read the following page - http://www.freertos.org/portlpc2368_Eclipse.html

Thanks Dave, I can now launch the yagarto tool but still have problem with the compilation:

make (e=2): The system cannot find the file specified.

make: *** [main.o] Error 2

What is the solution?

Now I can pass this step but still error 'cause some functions are not supported. Here some what I have from the output windows:

Any idea?

Hi all, i am facing this problem as well.
i am using codesourcery 2009q1-161-arm-none-eabi- with eclipse Galileo.
is there any update version of the demo code could be compiled by codesourcery 2009q1-161-arm-none-eabi- with eclipse Galileo?

Thanks very much.

please update me: jengoreda@gmail.com

Lao, you can fix it providin a syscalls.c file. That is because new newlib. Take a look at yagarto web site. They provide an example.

Let me help a little bit more. If you are using newlib 1.17, just create a file called syscalls.c like http://www.yagarto.de/download/yagarto/syscalls.c and compile together.

There is more information on http://www.yagarto.de/howto/yagarto1/yagarto_newlib.txt .
