9 5 Software 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. 5.1 Das 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.

In particular, the distributed copy currently expects a Windows BMP file named bdlogo.bmp to be present on the MMC card and writes it to the display, then loads an operating system image from a file named nk.nb0 to RAM address 0xa0030000 and executes it. Both of these are defined by the lines which resemble this: #define CONFIG_BOOTCOMMAND "mmcinit; " \ "fatload mmc 0 a0000000 init.scr ; " \

5.1 Das U-Boot 13 5.1.6 U-Boot Init Script The Das U-Boot boot loader comes with scripting facilities in the form of the Hush parser and the autoscript command. You should notice when first compiling the package that the Boundary Devices sample uses this to defer most board initialization to the MMC card. It does this by setting the CONFIG BOOTCOMMAND environment variable as follows. #define CONFIG_BOOTCOMMAND "mmcinit; fatload mmc 0 a0000000 init.scr ; autoscr a0000000 " In English, this instruc

5.3 Linux Support 16 5.3 Linux Support The Linux Environment for Boundary Devices boards consists of four pri- mary pieces, a toolchain, the kernel and device drivers, a user-space build tool based on PTXDist and a Javascript runtime used to demostrate the capabilities of the hardware. 5.3.1 Crosstool Linux Toolchain Before the kernel and applications can be built, it is first necessary to have a cross-compiler toolchain. The following examples show how we at Boundary Devices set up our toolchain

5.3 Linux Support 20 5.3.6 Userland build tool As mentioned before, we at Boundary Devices use a variant of an older version of the PTXDist tool to keep track of the cross-compilation needs for various libraries. This allows inter-library dependencies to be expressed, and also allows the canonical source locations to be used during a build. This should really be better documented, but the short and simple build instructions are as follows. $ wget http://boundarydevices.com/userland_20051126.tar.
