VIPER / VIPER-Lite Embedded Linux Development Kit Quickstart Arcom Embedded Linux (AEL)

Arcom Embedded Linux (AEL)

What’s in AEL?

AEL is a space-optimized Linux distribution based on Linux kernel version 2.6.

AEL includes many of the standard file, shell and text utilities. As well as the basic

Linux system, the default installation includes:

OpenSSH Secure Shell. •

•

Minimal X Window System.

Web server.

For a complete list of software and an explanation of how to add and remove packages

please consult the AEL Technical Manual.

Booting the system

Once the system has been connected and powered up (as described in Unpacking and

connecting up, page 10) the board automatically boots to a Linux prompt, as shown below.

The example below is typical for a VIPER-M64-F32 board:

Uncompressing Linux................. done, booting the kernel.

...

CPU: XScale−PXA255 [69052d06] revision 6 (ARMv5TE)

...

Machine: Arcom VIPER SBC

Memory policy: ECC disabled, Data cache writeback

Memory clock: 99.53MHz (*27)

Run Mode clock: 398.13MHz (*4)

Turbo Mode clock: 398.13MHz (*1.0, active)

For VIPER-Lite, the clock shows 199.07MHz instead of 398.13MHz (as

shown above).

...

Kernel command line: root=/dev/mtdblock2 rootfstype=jffs2 ro

console=ttyS0,115200

3 RedBoot partitions found on MTD device flash

Creating 3 MTD partitions on "flash":

0x00000000−0x0001f000 : "FIS directory"

0x0001f000−0x00020000 : "RedBoot config"

0x00020000−0x02000000 : "filesystem"

This partition table is for a VIPER-M64-F32 board (with 32MB of Flash

memory). The layout is different for boards with 16MB Flash memory.
