[[NJB3Firmware]]

NB: WIP

Apparently there was a Yahoo group called Nomadhack - I'm trying to join it (seems that it was inactive for two years) to see if there is any relevant info.

---++NJB3 Rockbox port

----+++Why bother?

The newer CreativeZVMPort, DellDJPort and other recent creative products use a modified version on the Creative Zen MTP firmware and a similiar TI DSP - progress made in one one port should (hopefully) be related to the other...

----+++Is it upgradable?
   * Jukebox 2 - Yes
   * Jukebox 3 - Yes
   * Jukebox Zen - Yes
   * Zen NX - Yes
   * Zen Xtra - Yes
   * Zen Touch - Yes
   * Zen Micro -Yes
   * Zen Microphoto - Yes

----++++Creative Zen Touch

From Australian release Creative Zen Touch 20 Gb, (Made in HK, 2003/2004):

   * "Touchpad" is driven by a chip labeled: ==Synaptics== =T1005 0423 CM2764.00=
   * There are 4 noticeable chips on the front of the main PCB under the LCD
      * One is presumably unlabaled, I suspect it could be the IDE controller - it has the cabled connector for the hard disk just below it and it has the same piece of yellow tape over it
      * SST 39VF400A 70-4C-EK (0410148-AB)
      * Texas Instruments TMS320 - DA255GHH (4A-44A8F3W) [[http://www.tikorea.co.kr/seminar/tidc/file/Silisand%20-%20Presentation%20TIDC%202005%20SILISAND4.pdf][Ti Korea PDF Documenting TMS320DA255]]
      * Samsung 431 K4S281632F-TC75 (S2816 WQF646PBC in smaller type)
      * LCD has a label on it that reads: =FGE-CMGG160104B-01 S0-MA01267 040832-BJ=
      * Hard disk - 4,200 RPM Hitachi Travelstar
