@appendix Writing @sc{sdbfs} image in standalone configuration
If you use @sc{spec} board in a host-less environment, or you use custom
hardware and @sc{spec} drivers and tools cannot be used, there is still a
possibility of writing @sc{sdbfs} through Xilinx JTAG.
@sp 1
In case of @sc{spec} running a reference bitstream provided with a stable
@sc{wrpc} release, you can simply program your Flash with @i{spec_top.mcs}
provided with the release binaries using for example Xilinx ISE Impact tool.
This @i{mcs} file already includes both @sc{sdbfs} image and FPGA bitstream.
In case of a custom gateware or hardware, you can download a standalone
@sc{sdbfs} image:
@example
$ wget http://www.ohwr.org/attachments/download/4144/sdbfs-standalone.bin
@end example
and generate a custom @i{*.mcs} file with your own FPGA bitstream. You should
use the following layout:
@multitable @columnfractions .1 .7
@item @code{0x000000} @tab your FPGA bitstream
@item @code{0x170000} @tab @sc{sdbfs} image
@end multitable
@sp 1
For example, to generate the @i{*.mcs} file for M25P32 Flash on @sc{spec}, the
following @i{promgen} parameters should be used:
@example
promgen -w -spi -p mcs -c FF -s 32768 -u 0 <your_bitstream>.bit \
-bd sdb-standalone.bin start 0x170000 -o output.mcs
@end example
After that, you can use the Xilinx JTAG cable and Xilinx ISE Impact tool to
write your @i{output.mcs} file to the Flash memory.
