5.1 Introduction

The TREK72x platform is one embedded system with Windows® Embedded CE 6.0.
The Windows® Embedded CE 6.0 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 spe-
cific 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 possi-
ble, which implies higher robustness to harsh environments.

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 Win-
dows CE image from external storage card. After download image done.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 Win-
dows CE image to DRAM and launch WinCE from DRAM, whenever loaded by exter-
nal storage card or system on-board flash chip.
