After planning for a long time, we registered 2 domain names, freetechnologyfoundation.org and freetechnologyfoundation.com . We were looking for some smaller name like ftf.org but it was already taken :(
We have planned to use the content management system Joomla
and it looks very simple and easy to use. Right now it is being hosted in Yahoo.com, but soon we'll get a permanent hosting space. We got to get the site ready and put the contents. Also, i have created a blog in that name freetechnologyfoundation.blogspot.com
Go to the homepage to know about its activities. I'll put up the history soon.

GCC Tool Chains for ARM processor
Cross Compiler for ARM processer:
www.arm.com provides a realview IDE software for the ARM processer. But its costly for a normal person to buy. It also provides a 30 day trial version CD. But there is also a free cross compiler for ARM processor, as GCC toolchains for ARM-ELF. It can be obtained from http://www.codesourcery.com/gnu_toolchains/arm/. All the tools can be downloaded separately and compiled following the instructions from any site. I followed the steps from http://www.6809.org.uk/gp32/build-cross-compiler.shtml.
http://www.codesourcery.com will surely answer any of the compilation and building problems. I could compile it very easily. But i had problems when i tried to compile a C file with the arm-elf-gcc. It gave me lots of errors while linking the object files. I was sitting with that for a day or so.
Error Message:
Just compile gcc with --with-fpu=fpa option to correct it :)

GCC Tool Chains for BF533
Free Cross Compiler for BF533 Processer is now comes with GCC and you can get it @ http://blackfin.uclinux.org/
Analog Devices gives the Visual DSP++ IDE for a 90 day trial period, which is really a good IDE for BF533. But my affinity towards Free Softwares made me to search for a Free cross compiler. http://blackfin.uclinux.org/ has the Gcc Toolchains for BF533 Processors and it can be downloaded from that site which is very active. I have downloaded it and installed it also. Its very simple to install. After extracting it, just run the install script in the Buildscripts directory.
Eg:
Assumption:
Am in my home dir. Created a build directory called Bfin-build. I have also extracted the toolchain in my home dir.
$ cd Bfin-build
$../bfin-gcc-3.4.05r4-2/buildscript/BuildToolChain -s /home/madhan/bfin-gcc-3.4.05r4-2
Thats it, it'll build everything by itself.
Append the path variables to the existing path variable.
Eg:
export PATH=$PATH:$HOME/Bfin-build/bin:$HOME/Bfin-build/sbin:$HOME/Bfin-build/libexec
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/Bfin-build/lib
Now you can try out the tools, like bfin-elf-gcc, etc :)
