Rio Karma

[jacoby]

I see nothing of the sort on the CD... maybe they stopped sending those files with the CD at some point?

The Ecos diff from last-rhepl is on the CD that came with every Rio Karma. Subsequent firmware releases didn't include any new modifications to Ecos itself. I believe that the licensing conditions allow anyone with that CD to repost the diff (but check first!); I don't have a copy to hand myself any more.

That's good to know - hopefully someone can track it down.

However, the firmware is still being distributed on rioaudio.com - shouldn't that website also be hosting a copy of the source diff, as per the RHEPL?  It's possible for someone to download the firmware from that website without ever having received the CD.

krazykit is going to send me a slightly banged up Karma soon, so I can start tearing it apart and getting pics of the mainboard and components. But I feel that like my Dell DJ, this is going to end up in pieces in a hardware box I have... all in the name of Rockbox.

If anyone has one fully working, intact Karma, PM me.

hi there!
my beloved karma died some time ago (harddrive issues, srollwheel broken...) so i teared it apart and did a scan of the pcb.
you can find it here

//edit: wrong link corrected//

i only scanned one side of the pcb as all the chips are located on that one side. on the back side there are only two buttons for volume control and the harddisk connector - the rest of the pcb is left free to provide space for the harddrive itself.

if you need anything else please let me know!

best regards,
spaceghost

With your kind permission, space_ghost, I'd like to post this to the wiki page for the Karma.

Hooray! 1000th post!

[space_ghost]

  that's perfectly fine for me!

[LambdaCalculus]

GodEater, have you heard any word from the eCos discussion list yet?

[GodEater]

Nothing at all - I gave up.

[LambdaCalculus]

Ah, crap. Back to the drawing board.

In the meantime, here's the output of lsusb -v on my laptop with the Karma attached:

Hello all. I hope this idea hasn't died out yet. I'd love to get rock box on my karma.

I wish I had more time to help. All I can really do is email people and pester them into submission. I've tried emailing DNNA, to no avail. However, I emailed Ecoscentric, the commercial arm of eCos, and got a prompt response as below. I'm going to give Red Hat a try next in the hope that something comes of it. I'm not holding my breath though.

Cheers,
Dave.

Hi Dave.

Unfortunately circumstances are against you. Your best chance of
acquiring the code is to politely persist with DNNA. Red Hat were under
no obligation to either publish the code online or make it available -
that is the responsibility of the authors - and I suspect the
contribution was lost within Red Hat after we left.

You could try and contact Red Hat who were the copyright holder and who
provided the license, but unfortunately I doubt you will get any
response or assistance from Red Hat in this regard as Red Hat no longer
have any interest in eCos. The current copyright holders, the FSF, will
be unable to help because this was all before their time.

I have a taken apart rio karma I'm willing to ship to anyone within the continental US.  The power button snapped off the PCB and I tried to take it apart and fix it.  I realized after some hours with a soldering iron that my fingers are not stable enough.  Since then I bought an e200 v1 and am incredibly happy with it as a replacement.

I'd just like it to go to someone whom could use it.  As a development platform it should still work perfectly.  It includes the dock also.  Email me off list.

can these picture of PCB be useful?

Depends if they're better then the ones already on the wiki.  If so, feel free to upload them there.
