| <h2>Purpose</h2> |
| |
| <p>The purpose of this project is to write an Open Source replacement |
| firmware for the Archos Jukebox <i>6000</i>, <i>Studio</i> and <i>Recorder</i> MP3 players. |
| |
| <p>The main emphasis and first target is the Jukebox 6000. |

| <h2>Warning</h2> |
| <p>All firmware mods on this page are still <i><b>highly experimental</b></i>. |
| Try them on your own risk. If you are not 100% sure of what you are doing, keep cool. |

| <a href="lock.html">harddisk password lock problem is solved</a>! |
| Development can now resume at full speed! |
| |
| <p><i>2002-01-29</i>: If you have feature requests or suggestions, |
| please submit them to our |

| |
| <p><i>2002-01-09</i>: Nicolas Sauzede |
| <a href="mail/rockbox-archive-2002-01/0096.shtml">found out</a> |
| how to |
| <a href="mail/rockbox-archive-2002-01/0099.shtml">display icons and custom characters</a> on the Jukebox LCD. |
| |
| <p><i>2002-01-08</i>: The two LCD charsets have been |
| <a href="notes.html#charsets">mapped and drawn</a>. |
| |
| <p><i>2002-01-07</i>: |
| <a href="mail/rockbox-archive-2002-01/0026.shtml">Jukebox LCD code</a>. |
| I have written a small test program that scrolls some text on the display. |
| You need |
| <a href="mail/rockbox-archive-2002-01/att-0026/01-archos.mod.gz">this file</a> |
| for units with ROM earlier than 4.50 and |
| <a href="mail/rockbox-archive-2002-01/att-0050/02-archos.mod.gz">this file</a> |
| for all others. (The files are gzipped, you need to unzip them before they will work.) |
| |
| <p><i>2001-12-29</i>: Recorder LCD code. Gary Czvitkovicz knew the Recorder LCD controller since before and wrote some |
| <a href="mail/rockbox-archive-2001-12/att-0145/01-ajbr_lcd.zip">code</a> |
| that writes text on the Recorder screen. |
| |
| <p><i>2001-12-13</i>: First program |
| <a href="mail/rockbox-archive-2001-12/0070.shtml">released</a>! |
| A 550 bytes long |
| <a href="mail/rockbox-archive-2001-12/att-0070/01-archos.mod">archos.mod</a> |
| that performs the amazing magic of flashing the red LED. :-) |
| |
| <p><i>2001-12-11</i>: Checksum algorithm solved, thanks to Andy Choi. A new "scramble" utility is available. |
| |
| <p><i>2001-12-09</i>: Working my way through the setup code. The <a href="notes.html">notes</a> are being updated continously. |
| |
| <p><i>2001-12-08</i>: Analyzed the exception vector table. See <a href="notes.html">the notes</a>. Also, a <a href="mail.cgi">mailing list archive</a> is up. |
| |
| <p><i>2001-12-07</i>: |
| 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. :-) |
| |
| <p>I've set up a mailing list: rockbox@cool.haxx.se. |
| To subscribe, send a message to <a href="mailto:majordomo@cool.haxx.se">majordomo@cool.haxx.se</a> with the words "subscribe rockbox" in the body. |

| <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> |
