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 ? ?
GSM modem TI Calypso? Speaks standard protocols with proprietary extensions. No further documentation available?
Quad-band transceiver TRF6151? ?
Analog baseband TWL3014? ?
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? ?
Touch Screen ? Connected to the s3c2442 similar to GTA01
Vibrator Simple motor attached to the PWM output of the s3c2442
Sound Codec Wolfson Codec Data sheet available at http://www.wolfsonmicro.com/uploads/documents/en/WM8753.pdf is that enough?
Sound Amplifier National Semiconductor LM4857 Data sheet available at http://www.national.com/ds.cgi/LM/LM4857.pdf is that enough?
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
Personal tools
