Toolchain Install

You will need to install the Blackfin Toolchain in order to work with Blackfin open source. Basically, visit the toolchain download page and download these files (where <version> is the latest version available):

  • blackfin-toolchain-<version>.i386.tar.bz2
  • blackfin-toolchain-uclibc-default-<version>.i386.tar.bz2

Then unpack them to /opt/uClinux/ by running the following command on each tarball:

$ sudo tar jxf <tarball> -C /

Then update your environment by running (you will need to do this in every new console; some people put this into their ~/.profile):

$ export PATH=/opt/uClinux/bfin-uclinux/bin:/opt/uClinux/bfin-linux-uclibc/bin:$PATH

If everything went as planned, you can run:

$ bfin-uclinux-gcc --version
bfin-uclinux-gcc (ADI-trunk/git-e311b75) 4.3.5
