Philips GoGear 3125
« on: March 11, 2008, 11:13:17 AM »
This will be a new Thread for the porting of Rockbox to the GoGear 3125

I take any Advice I can get! Fee free to help me since this is my first porting :-D I hope I don't make any mistakes!

Step 1:
The scan of the Hardware:

(It's just a photo because I have difficulties to take away the case)

Step 2:
List of components (and discription):

-Hynix KOR HY27UU08AG5M-TPCB 744A

-Chip-Set: SIGMATEL STMP3504 LAE-SB6 T05030 0738 CN
I think It's the CPU... but I'm not very sure
Documentation:

http://www.rockbox.org/twiki/bin/view/Main/SigmaTelSTMP3xxx

-FM tuner: TEA5767

-LCD: Giantplus
I don't know which model it is but here you have a picture:

Great to see another port! I would advise you to place all the info in a wiki page instead of the forum so it doesn't get lost.

One other component I see is the FM tuner: TEA5767

It's Sigmatel-based; the chip is a SMTP3054. More details here.

We need that you get a picture of the other side of the mainboard as well, because there may be more chips on the back.

Like you were told in IRC, you have to be willing to open your device entire to get shots. So you'll have to try and get the board out of the casing.

Another step you should also take is getting a firmware updater from the Philips website and see how the update process is done. This can provide lots of good information as well.

I should also take a moment to remind you to please follow forum guidelines and not double post. If you have anything additional to say and no one has responded to your previous post, then use the "Modify" button to add to your post.

I found a datasheet for the TEA5767 FM chip, and will post it up on the wiki page.

Also, I'll edit the page a little bit and make it look a little more professional. You can follow along with what I'm doing so you can see how to edit the wiki. ;)

BTW, there should be a (working) TEA5767 driver in Rockbox, so you (normally) don't have to code that one anymore :)

Yes, amiconn pointed that out to me on IRC. That handles one small portion, at least.

It's going to be getting a free toolchain for the SigmaTel chipset that'll be the real show-stopper, though.

I also found out something about the Display. It's made by Giantplus... Picture's coming soon. :-D I have to get the Scanner running under Linux *blow away the dust from the top* xD

But here are sum IDs which are on the LCD:

H-KLM167E71-1B-071103-R

and

KFM167E71-1A/41

If possible, can you scan the back of the LCD? I tried searching Giantplus' site, but can't find the LCD model we're looking for.

Also, look at the chips on the back of the device and post what you find on the wiki page.

Its great that you guys are interested, but without a compiler, I think you're just wasting your time.

There are no devices than the Buttons for the navigation on the Back and the LC Display.... But I'm working on it...

I think in about 20minutes the Scanner should work :-D
and after that I will post the Images in the wiki and look for an firmware upgrade :-)


Edit:

hmm I sent a mail to Sigmatel and got THIS replay... -.-

I am sorry but we only provide datasheets to qualified customers and distributors after appropriate legal documentation is in place.

That's to be expected. Not many chip manufacturers will just hand you datasheets if you ask. Most of them won't even let you see one without signing a whacking huge NDA, which effectively renders asking for datasheets moot, since we won't be able to read them. (NDAs usually state that you have to keep the information in datasheets confidential and not share them with anyone else.)

Also, as I stated above, having no free toolchain for the SigmaTel chips is going to be a big problem. Unless you're willing to pay around $12,000, and be the only one allowed to use the kit, there's not many options we have.

However, with Freescale Semiconductor recently purchasing SigmaTel, things may change; details on that are here if you're interested.

thank you for introducing me into another part of capitalism :-D I think I'll have to pay for the Datasheet... 12$ isn't too much... especialy now... ( I think one € is aboeut 1.5$)

The Partt with Freescale I don't understand... What does this contract me to us?
(I'm not a native Englishspeaker and didn't understand everything :-/ )


EDIT:
I read the wiki on how to work for a new port several times now... and also the Wiki PortingHowTo but I don't understand what I exectly have to do after I found everything about the Hardware... Do I only have to take an existing Built and change the values? Or do I have to write a totaly new Firmware?
