Welcome

You have found the home page for the Blackfin Toolchain project. This is the central site for all toolchain components whether you are targetting to run Linux or bare metal on the Blackfin. These components consist of:

• The GNU Binutils, which is a collection of binary tools, the main ones being as (the GNU assembler) and ld (the GNU Linker). The mainline binutils project can be found on the GNU pages, where a comprehensive manual can be found.
• The GNU Compiler Collection (gcc), which includes front ends for C (stable), C++ (stable) , Objective-C (Not ported), Fortran (stable), and Ada (not ported). The mainline gcc project can be found on the GNU pages, where a comprehensive manual can be found.
• The GNU Debugger (gdb), allows you to see what is going on `inside' another program while it executes -- or what another program was doing at the moment it crashed. The mainline project can be found on the GNU pages, where a comprehensive manual can be found.
• The generation of uClinux's flat format - elf2flt,
• Tools to support embedded file system generation for a variety of types, including:
  • ext2 with genext2fs
  • cram with cramfs
• Tools to support bare metal application development and booting - ldr-utils - which takes standard gcc elf files, and converts it into a format which the Blackfin bootloader can understand (called a loader file, or LDR)
• Libraries, including libdsp, newlib, libgloss and uClibc.
• Toolchain components support Canadian Cross Compiler. This means you no longer need to have a Linux host. You can develop bare metal applications, and Linux applications (not kernel) on a Microsoft Windows PC.
• JTAG tools: (both urjtag and gdbproxy) to program flash over JTAG, or debug a standalone application.
• Integrated Development Environments (IDE). The Blackfin GNU Toolchain plugs into many IDEs and graphical debuggers including Eclipse, Insight, DDD, the GNAT Programming Studio, Dev-C++ and Kdevelop or any of your other favorite editors like Kate, emacs, or insert your favorite editor here.

The source for all of these tools is avalible from our svn, and any of these tools should build on almost any host system, including all Linux and Unix based OSes (including Mac OS-X), and run on Windows in a coLinux or native ming32 environment. We try to provide stable binary releases for many architectures (x86/Linux, x86/Windows, x86/Mac OS-X), and will continue to increase this list.

Getting Help

We try to provide complete documentation about the GNU toolchain for the Blackfin processor. If you can't find what you are looking for ask in the support forums - and we can either add something, or point you to the right place.

Bugs

If you see a message like this:

internal compiler error: Segmentation fault
