Hello, David!
I'm sorry asking specifically you, I have wrote about my problem in
threads TinyOS-help & TimyOS-devel, but didn't get any answer :(
In our research laboratory in Institute of Radio-Electronics of
Russian Academy of Science we develope wireless
transmitters/receivers based on chaotic communication. And the core of
our platform is Atmel's microcontroller ATmega168.
I have wrote a test platform (based on Mica2's files - actually changed
ATm128 registers to appropriate ones of ATm168) that allows me to
perfom application Blink.
But when I'm trying to compile it, compiler exclaims, that "atmega168 is
unknown target". Indeed, when I saw supported targets by avr-gcc,
there wasn't ATmega168.
That is, AVR toolchain with TinyOS 2.0 is older that I need.
So, I have configured & installed Binutils 2.16.1 (./configure
--target=avr), GNU GCC 3.4.6 (./configure --target=avr
--enable-languages="c"), and the latest AVR Libc 1.4.4. I changed paths to new
versions of tools and tryed to compile Blink for mica2 platform, but
compiler showed me:
We use a patched avr-binutils to allow $ in identifiers (used by the
nesC compiler), so you need to apply the attached patch. In a binutils
tree, the following should work:
patch -p1 <tinyos-binutils.diff
This patch is for 2.15, I expect it should work for 2.16 too (the
changes are small).
FWIW, nesC 1.2.8 will have an option to use a different separator than
"$" (I can hear the crys of joy already ;-)).
Btw: this patch modifies both the AVR and msp430 assemblers.

What is it? Version conflict? I have chosen these versions of
GCC&Binutils which are described in readme of AVRLibC. Maybe, the
problem is in Nesc compiler? What I have to do with it?
Please, dont ignore my request!
