CM-X300: WinCE: Configuring Eboot

Introduction

CM-X300 firmware for Windows CE consists of two components: U-Boot and Eboot. U-Boot initializes hardware and transfers control to Eboot - Windows CE loader. Eboot waits for 3 seconds (default setting) and then loads the Windows CE image from the NAND Flash. To interrupt the boot sequence, press any key other than ENTER during the first 3 seconds.

Press [ENTER] to launch image stored in flash or [SPACE] to cancel.

Initiating image launch in 3 seconds.

When the boot sequence is interrupted, Eboot enters menu-driven configuration mode.
