SONY NWZ E43x (E435/E436/E438)
marmatty:
Cheers mates , my first time posting on rb forums.
Ok , so the player i'm talking about is a Sony NWZ E43x series [i personally got my hands on a 436F].
The player appears to be using a Sigmatel chip [maybe a 3600 , dunno for sure] and the firmware appears to be encrypted.
The firmware update program is done through a Sony-branded Sigmatel update-program-thingie [discovered it after dissasembling the .exe ].
So , altrough this might be against forum rules to ask , does anyone wanna start porting rb to this little thingie ?
[oh , btw , sorry if i posted some nonsense or stupidity , my skills don't quite match the job of rb developer]
Later Edit :
I have discovered that the chip is indeed Sigmatel based , and I'm also pretty sure it's the 3600 so this kinda makes rb development easy
The firmware structure complies to what is already available in the wiki , that is :
* bootmanager.sb
* hostlink.rsc
* hostlink.sb
* player.rsc
* player.sb
* stmfgmsc.sb
* updater.sb
Using the Sigmatel firmware extractor i was only able to get "bootmanager.sb" out of the player , but what i've found more interesting is an update program that is not Sony-firmware bound , this means we can upload our own files to the player , the program can be found at
http://www.maxfield.de/index.php?id=16&tx_maxproductslist_pi1[pro_uid]=131&L=0
along with the firmware for that player [bricks the sony if you try to upload it]
Also , i've discovered that the player can be unbricked by the use of the original Sony update program.
Hope this will get someone's attention

Did you read the sticky? If you plan to work on this then feel free to start a port page for this in our wiki. Just don't expect anyone else to do the work for you. Feel free to visit user forums for this device and get skilled users/owners interested in Rockbox. You're more likely to do this than to convince people here who don't own this device to drop cash just to work on a new port.
