Eagle hardware version

Eagle I : AD6484 (usb) AD6482 (uptopia) AD6483 (pci)
Eagle II : ADIKE6485
Eagle III : AD/IKE6486
Eagle Plus (adsl2+) : IKE6487 (utopia) AD/IKE6505 (usb)

The Eagle usb chipset can be split in 3 components :
- a Analog Front End that do the analog/digital conservion
- a front end that do some computing on the digital signal
- an usb device chipset

Analog Front End for eagle III, IV

It come as an external chip.
For adsl2+ : AD/IKE6488

Analog Front End for eagle I,II

It come as an external chip.
For adsl : AD6480

Front end for eagle IV

Eagle IV uses the stratiphy core.

It seems to be a ARC core.
There is some arc datasheets.
A gnu binutils support ARC platform. A binary toolchain can be found

Front end for eagle I,II,III

The dsp processor in the eagle is based on ADI dsp processor.
With the information included in the driver (24 bits instructions, 16 bits data) and the fact that ADI make some ADSL modem with adsp processor, we found that it is an adsp processor.

Looking at ADSP datasheet we can see similar features to eagle dsp :

IDMA boot
24bits instruction
16bits data
Internal memory and overlay stuff.

According to a sumary of adsp chip, IDMA overlay (p17), the dsp could be a ADSP-2187, ADSP-2188 or ADSP-2189.

The adsp insctruction could be found on the analog website : http://www.analog.com/processors/epManualsDisplay/0,2795,,00.html?SectionWeblawId=432&ContentID=33133&Language=English.

Software for adsp :

disassembler for adsp218x : http://www.dce.bg/~vladitx/adsp2181/ or http://download.gna.org/ueagleatm/deadsp.tar.gz
tool chain for adsp : http://www.bdti.com/faq/3.htm#33 (very old gcc : 2.3.3 !!!) (some links are not working anymore :( )
on analog ftp, there some dos assemblers that can be used with dosemu. Unfortunaltly it doesn't support new adsp instruction need for eagle adsp.

Firmware is sended to DSP it two stages

load main program (pageno eq 0), run CPU
load additional data/program pages at DSP request

The second stage is needed because DSP have limited memory

usb device for eagle I,II,III,IV

The usb part is based on cypress EZ-USB (the ADI driver source code give some hints).
Eagle IV don't support usb2 (we could have use new cypress).
The datasheet is can be found on the web :
