Revision as of 14:16, 17 October 2007
Many people are more interested in getting a completely (and openly) documented hardware platform than in getting one with "just" all drivers under GPL. Why is this so? Just imagine an open source kernel which is released under a copyleft license which is incompatible to the GPL. These poor developers would have to reverse engineer a so called "open platform" as they cannot use the available drivers and header files. If you are a GPL-is-the-only-true-license guy/girl: Don't be offended by this, it's simply about choice. :)
This page tries to give you an overview how open the GTA02 hardware is documented and where to get the documentation. Your help is needed! If you know anything which is missing just add it, if possible with a reference where the info is coming from.
Component | Name | Openness |
---|---|---|
CPU | Samsung S3C2442 | Docs still missing on Samsungs site, but here is a copy: http://www.elektronika.opatnet.cz/datasheet/U/um_s3c2442b_rev12.pdf |
NAND flash | Samsung? | Standard NAND command-set. |
GSM modem | TI Calypso? | Speaks standard protocols with proprietary extensions. Most of the proprietary extensions are present also in some BenQ and/or Enfora Enabler modems which have open documentation available on internet. See also GTA01 gsm modem. No further documentation available? |
Quad-band transceiver | TRF6151? | No interaction with software. |
Analog baseband | TWL3014? | No interaction with software. |
WiFi | Atheros AR6K | No documentation available! GPL'ed driver only. |
Bluetooth | Delta DFBM-CS320 Class2 Module using CSR BlueCore4? | Documented at http://www.bluetooth.com/Bluetooth/Learn/Technology/Specifications/ |
GPS | u-blox/atmel ATR0635 | http://www.u-blox.com/customersupport/gps.g3/ANTARIS_Protocol_Specification(GPS.G3-X-03002).chm |
Graphic Accelerator | SMedia 3362 | Documentation will be released in the future according to http://lists.openmoko.org/pipermail/community/2007-September/010175.html . Speaks OpenGL ES 1.2 according to vendor homepage. |
MicroSDHC | ? | Connected to the SMedia 3362 |
LCD | TD028TTEC1 module using a Toshiba JBT6K74 TFT LCD Driver Chipset? | No open documentation available! GPL'ed driver only. |
Touch Screen | ? | Connected to the s3c2442 similar to GTA01 |
Vibrator | Simple motor attached to the PWM output of the s3c2442 | |
Sound Codec | Wolfson Codec | Full data sheet available at http://www.wolfsonmicro.com/uploads/documents/en/WM8753.pdf |
Sound Amplifier | National Semiconductor LM4857 | Full data sheet available at http://www.national.com/ds.cgi/LM/LM4857.pdf |
Power management | Philips PCF50606 | Documented at http://www.rockbox.org/twiki/pub/Main/DataSheets/pcf50606.pdf |
Battery | Proprietary | Thankfully it seems to be compatible with a widely used and cheap other one ;) |
JTAG | ? | Standardized, BSDL file for the CPU will hopefully become available |
