Embedded Linux Announced for JUMPtec DIMM/PC

Sep 21, 1999 — by LinuxDevices Staff — from the LinuxDevices Archive — 7 views

Apex, NC — Using Linux for embedded applications on the tiny JUMPtec DIMM-PC/486 embedded PC just got easier, thanks to the new EMJ-Linux distribution, developed by EMJ Embedded Systems.

EMJ has compiled a small distribution that runs Linux on JUMPtec's DIMM-PC/486, saving hardware developers the hours of time required to modify Linux to run on the tiny embedded PC. The DIMM PC is a full featured 486 PC in the size of a 144-pin memory DIMM.

This development presents a welcome alternative to engineers wanting to use the DIMM-PC with Linux or those finding themselves with a Linux project and tight space restraints. EMJ Vice President Mark Estill elaborates, “Linux is the perfect operating system for embedded applications. Because it is flexible and an open source code, it speeds development time and reduces development costs. Our solution is perfect for embedded web servers and wireless applications, and we are very excited to be able to offer this to our developers.”

About the DIMM-PC/486

The DIMM-PC/486 from JUMPtec measures 40×68 mm (1.57 x 2.68 inches) but packs the same punch as a standard 486 PC. The DIMM-PC is ideal for use in high performance applications such as security apparatuses, medical instruments, factory automation and global positioning systems. It ships with 16 MB of DRAM, 16 MB of IDE compatible flash and supports two serial ports and a parallel port, as well as floppy and hard drive interfaces, a real time clock and watchdog timer, and an I2C-bus.

About EMJ-Linux

The EMJ-Linux distribution consists of a 1.4MB boot disk. This boot disk contains everything needed to do a network install of EMJ-Linux. Currently v0.9 is a 5.7MB compressed file (9.8MB uncompressed), designed to download directly to DIMM-PC's 16MB Flash Drive, or to an IDE Drive. Once loaded, the DIMM-PC with Linux will support Ethernet, TCP/IP, Telnet, FTP, WWW (Apache 1.3.9), as well as two serial ports, parallel, floppy, IDE and VGA.

EMJ-Linux is based roughly on Slackware v4.0 which uses the current Linux kernel 2.2.x. It will be kept up to date by EMJ as Linux revisions occur. EMJ will also develop similar Linux solutions for other JUMPtec products. The EMJ-Linux distribution is available on EMJ's Web site,
