Hi,

I think this demo is tested with toolchain GNUARM like other ARM7  
GCC demos though I’m not 100% sure. To build it with winarm, you need to  
include some extra code for system calls. I’m attaching inline my “syscalls.c”  
file. I don’t remember the exact web page which I found this code. You can use  
it to get rid of link errors. Or you can use gnuarm. Here arethe necessary steps  
in case you need them:

1) Save the attached file to somewhere in your project tree.  
2) Edit your makefile to include this file in the build process.  
&nbsp;&nbsp; For example you can add it under FREERTOS\_THUMB\_SRC.

I hope this helps.

Regards,  
Caglar

The LPC2368 docs actually recommend installing YAGARTO rather than GNUARM.&nbsp; This is just because this is what I tested it with.&nbsp; In anycase, the answer is the same.

If you are using the Eclipse projects from the [FreeRTOS.org](http://FreeRTOS.org) download then Eclipse knows nothing of your compiler or its install location, all it does is call the makefile.&nbsp; The compiler actually used will be the one that appears first in you PATH environment variable.&nbsp; If you open a command prompt and type "which arm-elf-gcc.exe" it will tell you which one its going to use (assuming you have which.exe installed).&nbsp; To use a different compiler just change the order in which they appear within your environment variable setup.

Regards.
