9 5 Soft w are features As pro vided b y Boundary Devices, the Neon R  b oard supp orts either Win- do ws CE 5 R  or Lin ux. T o simplify the installation of either, the Das U-Bo ot b o ot loader is in- stalled on our ev aluation b oards, and tw o MMC cards are shipped to allow the use of either op erating system. 5.1 Das U-Bo ot The Das U-Bo[...]

The GNUARM pro ject pro vides a w ealth of information needed to build a cross-compiler for ARM pro cessors. Thankfully , it also provides an installer . As[...]

5.1 Das U-Bo ot 11 y our application. In general, the file u-boot-1.1.2/include/configs/neon.h defines thes e c hoices. In particular, the distributed copy curren tly expects a Windows BMP file named bdlogo.bmp to b e presen t on the MMC card and writes it to the displa y , then loads an op erating system image from a file named nk.nb0 to RAM a[...]

5.1 Das U-Bo ot 13 5.1.6 U-Bo ot Init Script The Das U-Bo ot bo ot loader comes with scripting facilities in the form of the Hush parser and the autoscript command. Y ou should notice when first compiling the pac k age that the Boundary Devices sample uses this to defer most b oard initialization to the MMC card. It do es this b y setting the CONF[...]

5.2 Windo ws CE 14 5.2 Windo ws CE As men tioned earlier, the Neon R  b oard ships with a runnable Windo ws CE 5.0 image on MMC card. A Board Supp ort Pac k age is also a v ailable and necessary to tailor the op erating system for a giv en application. The follo wing sections describ e the pro cess of producing an image match- ing the one shipp [...]
