5Software features

As provided by Boundary Devices, the Neon￿R board supports either Win- dows CE 5￿R or Linux.

To simplify the installation of either, the Das U-Bootboot loader is in- stalled on our evaluation boards, and two MMC cards are shipped to allow the use of either operating system.

5.1Das U-Boot

The Das U-Boot Boot Loader is a full-featured loader for either Linux or Windows CE that supports a wide variety of options for loading your Op- erating System and application.

Boundary Devices ships U-Boot both as a binary image and as source code in the form of a patch that adds support for either Neon or BD-2003 devices.

The binary image may be burned directly to sector zero of the on-board flash.

The source code will require a set of Linux or Cygwin(Windows) tools for cross-compilation. The following section will detail the requirements and steps for building.

5.1.1Requirements for building under Linux

Since the Das U-Boot project uses GNU tools, most of the required compo- nents will generally be available on a GNU/Linux system.

The three pieces which may not commonly be installed are the bzip2 and wget packages and an ARM cross compiler.

Boundary Devices typically uses GCC-2.95.3 to create U-Boot images, since that matches what we use to build the Linux image to run on the Neon itself, but the binary distribution of GCC-3.4.3 from GNUARM is a nice alternative.

5.1.2Requirements for building under Windows with Cygwin

There are two primary requirements for building under Windows.

The first, Cygwin, provides a set of Unix utilities under the Windows operating system. Since the Cygwin installer allows components to be se- lected individually, the following list shows the requirements for building a Das U-Boot image with Neon￿R support. Note that this list is probably incomplete, but these should be the only required items which differ from the Cygwin installation defaults.
