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 -inculded, interrupt routing etc). +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, - -the following files should be -modified: - -- c/src/lib/libbsp/powerpc/virtex/startup/linkcmds - for the memory layout required - -- c/src/lib/libbsp/powerpc/virtex/startup/bspstart.c - Here you can select the clock source for the timers and the - serial interface (system clock or external clock pin), the clock - rates, initial baud rate and other stuff - -- c/src/lib/libbsp/powerpc/virtex/include/bsp.h - some BSP-related constants - -- c/src/lib/libbsp/powerpc/virtex/* - well, they should be generic, so there _should_ be no reason - to mess around there (but who knows...) - - +For adapting this BSP to other boards, you can specify several configuration +options at the configure command line (use "./configure --help" in this +directory).
