Post by: leub on August 31, 2005, 08:03:30 PM
Hello (excuse me for my english, but i'm french !:)
I would like to knows if someone knows if rockbox can work on an archos AV120???
And if somebody (if nothing exists) will made a version for this type of ARCHOS ???

Thanks a lot

No, Rockbox doesn't run on the multimedia/AV models.

Feel free to start the work to make it happen!

Time to drudge up the old threads! :)

A friend of mine gave me an Archos Video AV120 that needs some repairs; mostly a new battery and possibly a new hard drive as well. But I figured: whilst I make the repairs, why not check out the chipset and perhaps write up a few documents? Then I will post them for the whole fora to see! Then the message came: "Pinky! Are you pondering what I'm pondering?"

I'm not much of a coder, but I do have some knowledge of C, and I can read code. I'm willing to get the ball rolling on a Rockbox port for the Video AV100 series. Besides, we're long overdue for another Archos port, hee hee!

Even better would be to post all the info in the wiki so it doesn't get lost

I'm getting most of the notes I took together for that. I'll try and get the wiki page up this weekend.

I was also directed to ArchOpen (http://www.archopen.org/tiki=index.php) on IRC, so I'm checking out what info they have as well.

Great, this is what happens when you have too much to do all at once.

I'm having a little trouble getting a wiki page started (can anyone help me with starting a wiki page from scratch?), but here are some of the specs, as per the ArchOpen site.

http://www.archopen.org/tiki-index.php?page=AV1xx_Chipset

Apparently the AV1xx series are the AV3xx models with some minor hardware changes. If there's an AV3xx port, either being worked on or partially worked on, how hard would it be to adapt it to the AV1xx?

The CPU seems to be a TI TMS320DSC25; ARM7TDMI core; this one's different from the CPU in the ZEN and Dell Digital Jukebox players. The iPod and H10 use ARM7TDMI already.

Sound DSP looks to be another MAS chip; the MAS3587F. I don't quite know if it's hardware or software decoding; I've got to get the data sheets out again.

There's a ATMEL ATF1504ASV 15AC100 0238 Programmable logic device as well. I have the data sheet for this as well, I think. If not, then I'll look for it.

Two IS42S16400A ISSI chips for RAM; the device has 16MB of RAM [64 Mbit - 8 Megabyte]; used for the audio buffer.

The Flash is a SST39VF400A chip with 256kB Flash ROM; the device is easily firmware upgradeable like most of the older Archos devices via a simple firmware download. I figure this one can be flashed to make Rockbox a permanent replacement as well.

USB is handled by a CY7C58300 56LFC USB 2.0/ATA/ATAPI bridge chip.

The AV1xx have a RTC, powered by a M41ST84W STMicroelectronics Serial RTC.

The LCD is a L2E1811D from Epson; I'm not sure exactly what the model is. Hell, I'm afraid of even taking it out of the device (it's very, very flimsy and may easily break!)

I have most of the data sheets already. But can someone give me a little info about starting a new wiki page?

Sure - just typed the name for the new page in the "Go" text box at the top, hit enter. The wiki will notice there's no such page, and offer suggestions for what you wish to do. You'll note one of those suggestions is   "If you would like to create this page" - and then there's a big "Create this topic" button at the bottom of the page. Away you go ;)

Thanks GodEater! Time for me to get the data sheets I have together and get this page started!

Okay, here's the initial wiki page. Tell me what you think:

I think I should at post an update about the Archos AV1XX port while I have a moment.

I have to set this aside for a while, because the AV120 I was fixing up is back in its original owner's hands as of July 5th, and I can't exactly purchase another one now, since I need to save money for a trip to Boston soon. I'll try to get another one off of eBay for research purposes after I return.

In the meantime, I'm going to continue to at least gather up more information about the AV120, but I also am waiting for wind of the Zen Vision:M port (http://forums.rockbox.org/index.php?topic=3320.0), since both of these systems (as well as another port I want to work on, the Dell Digital Jukebox) use the Texas Instruments TMS320 family of CPUs. If there's some work done, I could adapt it to the Archos AV120 and the Dell DJ and I should get some results with the appropriate tweaking and coding.

So for now, please do NOT ask about port progress, because I had to put this on the back burner for a while, and I don't know when I can get another AV120. The other devs can contact me about information if they wish, however.
