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

Support 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.

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 <blockquote> #define BF533_HZ 50 </blockquote> to a value like 70000

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 your apt.sources

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.

Hardware Debugging

During devolping of this BSP the Icebear JTAG adaptor has proved to be very helpful. ​http://www.section5.ch/icebear

Wishlist

• Proper support for Data and Instruction Cache
• Filesystem support for the on-board flash
• GDB Stub for debugging via Serial Port
