USB Host

The USB Host controller is inside the S3C2442

It should also be possible to use host mode with externally-provided power. This will allow the FreeRunner to be connected to a USB device and powered at the same time.

  • Connect gnd, d+, d-, +5 to your USB device
  • Connect a 15k ohm resistor between d+ and ground
  • Connect a 15k ohm resistor between d- and ground
  • Connect a 47.5k 1% ohm resistor between the ID pin and ground
  • Connect gnd, +5 to your >500mA power source

The last two points are taken care of by the external AC charger, so you could use a Y cable that brings the AC adapter together with a cable that connects up the rest.

USB Device

Information from [1].

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.

Certification

FCC

    • 850/1800/1900 Band, FCC ID: EUNGTA02
    • 900/1800/1900 Band, FCC ID: EUNGTA02E

NCC

USB Host

The USB Host controller is inside the S3C2442

It should also be possible to use host mode with externally-provided power. This will allow the FreeRunner to be connected to a USB device and powered at the same time.

  • Connect gnd, d+, d-, +5 to your USB device
  • Connect a 15k ohm resistor between d+ and ground
  • Connect a 15k ohm resistor between d- and ground
  • Connect a 47.5k 1% ohm resistor between the ID pin and ground
  • Connect gnd, +5 to your >500mA power source

The last two points are taken care of by the external AC charger, so you could use a Y cable that brings the AC adapter together with a cable that connects up the rest.

USB Device

I2C Devices

The I2C is a simple communication standard intended to move small amounts of data a few inches between chips. Please see Neo I2C Devices for more information & a list of devices & the addresses currently in use & documented for the Neo1973.

Audio

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.

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

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 for 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
  • Mass production A5 trial run start from 2008 March, including some resistor/capacitor change compare with inital 100 pcs prototypes A5, and prototypes for GTA02 developers was tracked in the Prototypes Page
  • Coulomb counter issue fixed
  • USB host power switch fixed
  • Need add capacitor for PMU Vbat input for stability issue, this could be done by direct SMT or hand rework
  • Need rework (still using SMT in production) add capacitor for PMU Vbat input for PMU stability issue.
  • Need manual rework GSM IR UART path a 100k pull down for better GSM deep sleep
  • ATAG_REVISION: 0350

GTA02v6

Mass production candicate version 3/Mass production version

A6 will be fine tune version of A5, only minor schematic change for better product quality and version control. Capacitor and resistor change A6 also on mass production A5

  • First 100 pcs might start from end of 2008 March
  • Add capacitor space for Vbat, reduce the SMT effort
  • Add GSM IR resistor for better GSM deep sleep
  • Reserve 3 GPIO for hardware version control

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.
