Build the Toolchain

Preparations

Before you can install the toolchain, you need the following software packages

Build Essentials (make,...)
GNU C++ Compiler
Blackfin Cross Compiler Toolchain (bfin-uclinux-xxx)
Git or wget+tar+gzip, according to how you want to download the toolchain-package

To get the latest version of the toolchain, simply checkout the appropriate git repository with the line:

git clone git://github.com/krater/rigol-toolchain.git

Switch to the resulting directory and start a make with

cd rigol-toolchain;make

If this works without errors and warnings you can install the toolchain with

sudo make install

Now you are prepared for patching your firmware and building the examples.
