OpenMoko is a software distribution stack that sits on top of a hardware platform. The Neo FreeRunner phone is the second hardware platform to take advantage of OpenMoko. You can find specifics of the hardware by reviewing this introduction page and the pages in the category as shown at the bottom of this page.

NOTE: This page is about hardware that is currently in design/prototype phase, changes are frequent

  • 184 +/- 5 g (6.5 ounces)

Main components

Processor

The main Processor (CPU) of the Neo1973 GTA02 is a Samsung S3C2442B B54 (running at 400 MHz)

Flash

256MB integrated Samsung NAND flash inside the 2442 multi-chip package, attached to the S3C2442 NAND controller

GSM/GPRS

The GSM (including GPRS) modem is Texas Instruments Calypso based.

CALYPSO digital baseband

Unfortunately we cannot provide many details on the GSM chipset due to very tight NDAs. However, this is not neccessarily required, since it interfaces using a standard UART serial line with the S3C2442. On that interface, GSM 07.05, GSM 07.10 and other standardized protocols are used.

  • Driver: none needed, talks standard NMEA
  • Datasheet: Atmel ATR0635

microSD-Card

The Neo1973 has one microSD aka Transflash slot. It should support SDHC, and 4GB card has been tested. Anyone with 8GB card? MicroSD slot is under battery.

LCD Module (LCM)

This is a 2.8" diagonal (1.7" x 2.27" - 43mm x 58mm) 480x640 toppoly (tpo) TD028TTEC1 module, using a Toshiba JBT6K74 TFT LCD Driver Chipset.

Wolfson Codec

There's a WM8753 Wolfson Microelectronics CODEC (This is not a 'smart' codec that can interpret MP3/... it is a simple dumb 'sound card'.

Mono Amplifier

There's a National Semiconductor LM4853 Mono Amplifier at the analog audio output of the WM8753

Analog wired Headset

There's a four-ring 2.5mm stereo jack which provides connectivity to old-fashioned wired headsets.

The headsets used by Motorola smartphones (A780,A1200, ...) and the V-360 have a compatible configuration.

Bluetooth Headset

This one is wired via PCM bus from the CSR Bluetooth chip to the Wolfson codec.

A Philips PCF50633 04 N3 is used for power management.

Battery

The Neo FreeRunner (GTA02) Battery is mechanically and electrically compatible with the Neo1973 GTA01 Battery, as well as limited compatibility with a Nokia BL5C battery. According to this post on the mailinglist. Photo of the battery inside the Neo1973.

Buttons

The Neo1973 GTA02 features two buttons:

  1. The Power Button
  2. The "Aux" button

Accelerometers

Two ST LIS302DL

History

GTA02v1

First generation of prototypes that was given to internal OpenMoko software developers. Total 30 pcs fabricated.

  • It is working just fine, but still based on 2440, with external NAND/SDRAM and no NOR flash
  • Using the PCF50633 05 N3 due to 04 N3 not available, re-work power for basic schematics verification
  • Using GTA01 SIM socket
  • Add external debug port
  • Still using Global locate A-GPS
  • ATAG_REVISION: FIXME

GTA02v2

Second generation of prototypes, Total 50 pcs run at Taipei SMT factory MOUNT

  • Ideal is have 256 MB NAND on Samsung package, Due to chip availability Start using S3C2442 B43
  • Using correct PMU PCF50633 04 N3
  • Change new SIM socket
  • Change to u-blox A-GPS
  • Change LCM power from 3.3v to 1.8v
  • USB power switch layout/pin assignment mistake, could not verify USB host supply 5v function
  • GPS function verified ok with good senstivity

GTA02v3

Production verification version, 2007/10/11 28 pcs fabricate at FIC SuZhou

  • Still using S3C2442 B43 for hardware verification
  • Using control pilot run to verify S3C2442 B54 chips


GTA02v4

Mass production release candicate version 1

2 weeks after v3 gerber out, release the v4 gerber, and 2007/10/20 20 pcs fabricate at FIC SuZhou

  • Change LCM power from 1.8v to 3.3v from display stability issue
  • fabricate another 200 pcs for yield rate/production verification
  • fabricate 50 pcs with S3C2442 B43 (128 MB NAND) for quality comparsion
  • USB host power chip have some output voltage stability issues with Vb/Vcc comes from different power source, need layout change to fix the issue
  • Battery Coulomb design not working on A4

GTA02v5

Mass production candicate version 2/Mass production version

  • First batch fabricate 2008/1/14 at FIC SuZhou
  • Coulomb counter issue fixed
  • USB host power switch fixed

Debug Connector

This is the connector used to connect the Debug Board and possibly other hardware.

Connections are:

  • 39 - GND
  • 38 - STDI
  • 37 - _RESET
  • 36 - STMS
  • 35 - STCK
  • 34 - STDO
  • 33 - GSM_EN
  • 29 - _STRST
  • 19 - X_I2C_SCL (H-TP4703)
  • 18 - X_I2C_SDA (H-TP4704)
  • 17 - SPI_CLK0
  • 16 - SPI_MOSI0
  • 15 - SPI-MISO0
  • 14 - SS0
  • 13 - EINT3 (H-TP4705)
  • 3 - CONSOLE_TXD (H-TP4701)
  • 2 - CONSOLE_RXD (H-TP4702)

Distinguishing hardware revisions

Inside the Bootloader

Every hardware revision has its own u-boot image type. Thus, the bootloader has the revision hard-coded. The hardware revision is passed on to the kernel via the ATAG mechanism (ATAG_REVISION)

Inside the Kernel

The kernel receives the ATAG_REVISION during bootup, and saves its contents in the "system_rev" global variable.

From Userspace

The kernel exports the system_rev variable in /proc/cpuinfo as "Revision :" line.
