= EZKit533 =


This is an evaluation Board from Analog Devices for the Blackfin 533 CPU.
Information can be found here :
http://www.analog.com/en/prod/0%2C2877%2CBF533%25252DHARDWARE%2C00.html

The source for RTEMS for the Blackfin CPU is currently only available via CVS checkout.
This BSP has a Console Driver for a the built-in UART which supports
polling or interrupted mode. It does also have a driver for core
clock and timer. The BSP runs in supervisor mode.

The BSP executes on real hardware as well as on the skyeye simulator.

= Toolchain =


Thanks to Ralphs continous improvements on the RTEMS Toolchain packages you can download automatically
generated RPMS of the toolchain from [http://www.rtems.com/ftp/pub/rtems/linux/4.8]

If you do use a debian based distribution you might add a line like :
<blockquote>
deb http://www.itasat.ita.br/rtems/ unstable main 
</blockquote>
to the file /etc/apt/apt.sources and then do
<blockquote>
apt-get install bfin-rtems-binutils bfin-rtems-gcc skyeye-rtems
</blockquote>

If you want to build your toolchain by yourself : donwload binutils 2.17, gcc 4.2 and newlib 1.15,
apply Ralfs patches from RTEMS CVS (inside the contrib directory) and compile the for the bfin-rtems
target.
= Compiling RTEMS for Blackfin =


So far the source for RTEMS for Blackfin is only available in CVS trunk. See [wiki:TBR/Delete/RTEMS_CVS_Repository RTEMS CVS Repository] on instructions how to
checkout from CVS. To compile RTEMS do :

run the bootstrap script in the RTEMS source directory.

run the configure from a directory outside of RTEMS source
{{{
../rtems-cvs/configure --target=bfin-rtems --enable-posix --disable-networking --enable-cxx 
    --enable-rtemsbsp=eZKit533 --prefix=/usr/local/rtems
}}}
run
{{{
sudo make install
}}}
you can find hello world in /usr/local/rtems/bfin-rtems/eZKit533/lib/rtems-4.8/tests/
= Skyeye Simulator =

The Skyeye Simulator supports Timer and UART. The used skyeye configuration
file is :

{{{
arch:blackfin
mach:bf533
}}}

The current versions 1.2.2 as well as subversion need a small hack to get the
rtems timer running. In the file arch/bfin/mach/bf533_io.c change the line
{{{
#define BF533_HZ 50
}}}
to a value like 70000
= Hardware Debugging =


During devolping of this BSP the Icebear JTAG adaptor has proved to be very helpful.

= Live CD =


There is a Ubuntu Edgy LiveCD with a complete RTEMS Blackfin development Environment available
at http://www.itasat.ita.br/portuguese/Ubuntu/ubuntu-bfin-live.iso

Beware this CD has not yet been updated to ubuntu edgy. It is also not able to run bootstrap
from the current CVS but might be a good starting point to setup a development machine.
= Wishlist =

 * loading from flash via bfin bootloader (beeing finished by Alain Schäfer)
 * Proper support for Data and Instruction Cache
 * Filesystem support for the on-board flash
 * GDB Stub for debugging via Serial Port
= Test Reports =


CVS head -- (25 October 2006) Alain Schäfer reports sucessful execution of Hello, Ticker, Paranoia and other tests
on the Hardware as well as on Skyeye
