Hello. I'm struggling to get the Freertos to run on a SAM7-EX256 board,
with no succes so far. Does anybody has an GCC example?

Thanks,
Tudor

Hello Andreas,

compiler and the makefile is not suted for this software. What should I

It should work with WinARM. What problems do you have exactly?

When I try to "make clean" the project you sent me I get the following
message:
"touch Makefile
process_begin: CreateProcess((null), touch Makefile, ...) failed.
make (e=2): The system cannot find the file specified."

and when I try to "make" the project it says it has no rule form make
all.

I have made a project looking on the internet. I
can program the code but it doesn't work well. It has a simple serial
module that just sends characters on the serial port of the board. The
problem is that it is just sending a few characters and then it stops. I
have been looking all over to see why it does that, but still I can't
imagine where it is the problem. I may be when the FreeRTOSs' scheduler
is taking over. I tried to attach the project but the archive it is too
large (aprox 300kb). Could you please tell me where should I look for
the problem?
Thank you,
Tudor

You can take a look at one example I have used for my board here (with
some modifications).

http://www.siwawi.arubi.uni-kl.de/avr_projects/arm...

It has the same problem, I only receive one character an then nothing. I
have made some modifications to the project, as I want to receive on a
computer the sent characters.

Thanks
