Virtex only supports single processor operations.

Configuration

This board support package is written for a typical virtex/PPC FPGA system. The rough features of such a board are described above.

When a new virtex FPGA system is created (using the Xilinx design software), a parameter file "xparameters.h" is also created, which describes the basic features of the hardware (like peripherals included, interrupt routing etc.).

This BSP normally takes its basic HW description for the file "xparameters_dflt.h", which describes my FPGA system. When this BSP should run on a different hardware, a path to the proper "xparameters.h" can be provided on the "configure" command line.

For adapting this BSP to other boards, you can specify several configuration options at the configure command line (use "./configure --help" in this directory). Here is an example for the top-level configure invocation:

/path/to/rtems/sources/configure \
  --target=powerpc-rtems4.11 \
  --enable-rtemsbsp=virtex \
  --enable-maintainer-mode \
  --enable-posix \
  --enable-tests \
  --disable-networking \
  'RTEMS_XPARAMETERS_H="/path/to/xparameters.h"' \
