SBC2440-I User Guide (Please read the instructions of the User Guide thoroughly first before operations, and be aware not to damage system bootloader)
Preface SBC2440-I is an ARM9-based embedded computer platform designed and manufactured by Embest Info & Tech Co., LTD. Based on SAMSUNG’s ARM processor S3C2440X. S3C2440X uses ARM920T kernel, with whole-performance MMU. It is suitable for movable handheld device, characterized by high performance, low power consumption, diverse ports and compact size. SBC2440-I is designed to meet various features of this chip. SBC2440-I design satisfies features of S3C2440X embedded chip, integrates the features of latest PDAs/handheld devices, so it serves as an embedded computer platform suitable for both single board computers and development board. Entire board occupies an area of 134mmx93.5mm only. As the first choice of software, we employed the free embedded operating system arm-Linux in the open source code, based on this platform and its development toolkit, we compiled and transplanted colorful softwares for your use and reference, e.g. Mp3 player in console mode, Web server ,Ftp and its server, Telnet and its server etc. The binary executable programs and its source code of these softwares are included in the supplied CD, and have been pre-installed in SBC2440-I, user can use it immediately after start-up. In addition, SBC2440-I can also run Windows CE4.2.net. Windows CE system including Word reader, Excel reader, Power Point reader, photo browser, Pdf reader, Word editor, IE, media player, and some games, etc. Finally, welcome to use SBC2440-I, and present your valuable comments.
