TS-7250 MANUAL

INTRODUCTION

Linux OS Support

The ARM processor (the EP9302) comes from Cirrus and the platform is very similar to
the Cirrus EDB9302 evaluation board. Cirrus has strongly promoted running Linux on this
chip and has done most of the legwork in creating a patch set to the Linux 2.4 kernels, but
we have also had to modify the Linux Kernel (TS-Kernel) so it can support the 8MB on-
board Flash chip (via mtd drivers), the compact flash IDE driver, and the A/D converter. If
you want to use Linux and aren't tied to the x86 architecture, the TS-72XX boards can be
very cost-effective.

The  TS-72XX  SBC's   are  shipped  standard  with  the
compact   TS-Linux   embedded   operating   system
installed   in   the   on-board   Flash   memory.   The   full-
featured Debian Linux can also be used with an NFS
root   file   system   or   larger   Flash   drives,   such   as
Compact   Flash   cards,   SD   cards   and   USB   flash
drives. The TS-Kernel used is based upon the version
2.4.26, patched and compiled for the Cirrus EP9302
ARM920T   processor,   and   is   real-time   capable
through RTAI.

The root file system used by the Linux OS can be any of the following:

✔

JFFS/YAFFS file system image in the on-board Flash (if using RedBoot, it should
include the option root=/dev/mtdblock1 to instruct the kernel to boot here)

✔

EXT2 file system image in the Compact Flash card (if using RedBoot, it should include
the option root=/dev/hda)

✔

NFS root, via Ethernet port (if using RedBoot, it should include the option root=/dev/nfs
nfsroot=<IP>:<DIRECTORY> ip=dhcp)

Note

The TS-Kernel supports the

Real-Time

Application Interface (

RTAI

project),

making the embedded operating system capable of handling applications with
hard real-time restrictions.

Other OS Support

The

TS-7250

can be loaded with other operating systems such as Windows CE, NetBSD,

etc. Technologic Systems will provide support for these, and possibly other operating
systems, in the future. Currently, only

Linux

and

NetBSD

are supported on the

TS-7250

.
