6.1 Introduction
The TREK510 platform is one embedded system with Windows® Embedded CE 5.0. The
Windows® Embedded CE 5.0 is a compact OS that occupies less storage space or system
resources compared with other operating systems such as Windows
®
XP. By its modular
nature, it is possible to choose those functions that are useful for specific application. Not
only reducing the system resources required, but also reduces start ‐ up time. In the field of
embedded applications, this is an appealing feature because the impact of downtime would
be minimized.
Furthermore, the small storage space it needs makes OS on solid-state disk possible, which implies higher robustness to harsh environments.

6.2 Windows CE Startup Procedure
Windows CE image can be loaded by two methods, first way is by SD / MMC storage card, and
second way is by system on ‐ board chip. Storage card is higher boot priority than on ‐ board
system flash chip. In BOOTLOADER criteria, it will first read the Windows CE image from
external storage card. After download image done, booloader will burn image to on ‐ board
flash chip automatically. If external storage card is unavailable or no Windows CE image inside,
BOOTLOADER will load the Windows CE image from on ‐ board system flash chip. BOOTLOADER
copy Windows CE image to DRAM and launch WinCE from DRAM, whenever loaded by
external storage card or system on ‐ board flash chip.
