I just wrote this web page to announce descramble.c.

I've disassembled one firmware version and looked a bit on the code, but no real analysis yet.

Summary: Lots of dreams, very little reality. :-)

<h2>About the hardware</h2>
|
|
|
|
<p>I wrote a <a href="internals/bjorn.html">"dissection" page</a> some months ago,
|
|
showing the inside of the Archos and listing the main components.
|
|
I have also collected a couple of <a href="docs/">data sheets</a>.
|
|
Also, don't miss the <a href="notes.html">research notes</a>
|
|
from my reverse-engineering the firmware.
|
|
|
|
<h2>About the software</h2>
|
|
|
|
<p>The player has one version of the firmware burnt into flash ROM.
|
|
The first thing this version does after boot is to look for a file called
|
|
"archos.mod" in the root directory of the harddisk.
|
|
If it exists, it is loaded into RAM and started.
|
|
This is how firmware upgrades are loaded.
|
|
|
|
<h2>Dreams</h2>
|
|
<p>Ok, forget about reality, what could we do with this?
|
|
|
|
<ul>
|
|
<li>All those simple mp3-play features we sometimes miss:
|
|
<ul>
|
|
<li>No pause between songs
|
|
<li>Mid-song resume
|
|
<li>Mid-playlist resume
|
|
<li>No-scan playlists
|
|
<li>Unlimited playlist size
|
|
<li>Autobuild playlists (such as "all songs in this directory tree")
|
|
<li>Auto-continue play in the next directory
|
|
<li>Current folder and all sub-folder random play
|
|
<li>Full disk random play
|
|
<li>REAL random (if press back it goes to the previous song that was played)
|
|
<li>Multi song queue (folder queue)
|
|
</ul>
|
|
<li>Faster scroll speed
|
|
<li>Archos Recorder support. Most of the hardware is the same, but the display and some other things differ.
|
|
<li>All kinds of cool features done from the wire remote control, including controlling your Archos from your car radio (req hw mod)
|
|
<li>Ogg Vorbis support [unverified: the MAS is somewhat programmable, but enough?]
|
|
<li>Support for megabass switch (req hw mod) [unverified: I just saw the DAC docs shows how to do it switchable. we need a free port pin to be able to switch]
|
|
<li>Player control via USB [unverified]
|
|
<li>Memory expansion? [doubtful: the current DRAM chip only has 10 address lines. we'd have to pull off one heck of a hw mod to expand that]
|
|
</ul>
|
