Details

See also the explanation in german language I wrote in the passed Wehavemorefun Wiki.

The AR7RD is the original Reference Design by TI to build an AR7 based DSL router.
The WLAN variant adding the ACX-111 Reference Design by Radia is the AR7WRD.

These 2 IDs were the original values of the ProductID variable, to identify the board a firmware is running on.

Hardware

There are hundreds of routers based on the AR7RD design, their hardware mostly is the same.
The main thing where they differ is the selection of a possible switch chip for routers with 4 LAN ports.

Note that the AR7 was the first single-chip DSL router of the world.

SDK

The SDK for the AR7 was a ready-to-use router OS named PSP (Platform Support Package) or NSP (Network Support Package).

Bootloader

TI provided the ADAM2 bootloader, or its successor PSPboot.

The Bootloader-Environment originally was accessible at /proc/ticfg/env or at /proc/avalanche/env.
It contains many variables we all know, including the TIATM-Environment. Some variables have differung names in PSPboot.
Some vendors added custom variables or removed some variables.

Example from a CastleNET AR801 which uses PSPboot. The comments show ADAM2 variable names:

# cat /proc/ticfg/env

Kernel

It contained a MontaVista Linux with Kernel 2.4, typically 2.4.17_mvl21-malta-mips_fp_le.
This kernel is still used for early Box-Models which did not have the ressources for an upgrade to Kernel 2.6.
Besides this TI provided a bunch of proprietary Kernel-Modules as binary blobs:

Like all TI modules these have a Proc-Filesystem interface at /proc/avalanche.
Example from a Sphairon Turbolink AR860:

# ls -1 /proc/avalanche

Webinterface

The following screenshots come from a Sphairon Turbolink AR860, an AR7RD router with one LAN port, a DSL port and
a connector for the Power-Supply. Its hardware equals the smallest of all Box-Models, the FRITZ!Box SL.

Design und colour of the Webinterface equal the original from the TI SDK, all Branding is just replacing the TI logo top left.
