.SH NAME

tos-storage-pxa27xp30 - Generate storage volume description code
.SH SYNOPSIS

\fBtos-storage-pxa27xp30\fR
.SH DESCRIPTION

\fBtos-storage-pxa27xp30\fR reads a user specification describing the
layout of storage volumes on an embedded P30 flash in the Intel Xscale
PXA27X series processor, and generates code describing that layout for
use by the TinyOS 2.0 storage subsystem.  The user specification is in
XML and is read from standard input. The code is written to standard
output.

This program is normally invoked automatically by the TinyOS build system
when your application directory contains a \fBvolumes-pxa27xp30.xml\fR file.
.SH EXAMPLES

  tos-storage-pxa27xp30 <volumes-pxa27xp30.xml >build/telosb/StorageVolumes.h
.SH SEE ALSO

.IR tos-storage-pxa27xp30 (1)
