LOSA is the much more progressed module type than LOC. Its capability is almost the same as the Pentium II PC, therefore the usage of LOSA is different with LOC. The specifications are as follows :
 
 
 
The best solution for adopting Linux onto Embedded product

Possible to adopt all the H/W and S/W that is related to the development of those product which is planed to connect with internet. E.g. internet appliances, industrial controllers etc.

Building the development environment through the Console (Desk top Linux environment)

Only to make application S/W is enough to develop product on the basis of powerful multitasking OS

Materializing of real time kernel(possible to Interrupt driven control)

TCP/IP protocol stack

Materializing file system in the flash ROM not in Hard Disk

Possible to save and access of development program through NFS(Network File System)

It doesn’t need additional emulator to develop applicable program because On-Line (target board) debugging is materialized.

Low electronic consumption setting (Maximum 100mA)

Built-in LAN(Ethernet

Built-in LCD controller

Built-in web server

Possible to connect by PPP

It is a tool for evaluation able to be used as a simple development tool for testing LOSA functions. If you connect the RS-232C port of PC in which a terminal emulator program such as Linux minicom or Windows HyperTerminal is stored to the RS-232C port of the evaluation board and supply electric power, the booting process is displayed on the terminal screen and finally a prompt is displayed.

LOSA operates as a Linux machine providing the same interface as desktop Linux. The user, after he/she sets up the IP address suitable to his/her own LAN(The setting example is showed in the operating manual) can visit the basic home page stored in LOC by using the provided GCC compiler, or immediately perform a simple function test after he/she prepares/complies the same program as "Hello Linux " on the host PC and stores it in the LOSA using NFS and implementing it. The user familiar with TCP/IP or other technology can implement a gateway that is able to connect the equipment with built-in RS-232C to Ethernet using only the evaluation board.
