Contents

Main components

Processor

The main Processor (CPU) of the Neo1973 is a Samsung S3C2410AL-26 (Capable of running up to 266 MHz)

Flash

64MB Samsung NAND flash (K9F1208U0B) attached to S3C2410 NAND controller.

This is the only flash memory in the device. The S3C2410 boots directly from nand, using the S3C2410 Steppingstone.

We only use free software, no proprietary flash file systems. For a full description of how it is used, see NAND bad blocks

RAM

128MB SDRAM (2x Samsung K4M511633C) attached to S3C2410 SDRAM controller

GSM/GPRS

The GSM/GPRS modem is Texas Instruments Calypso based.

CALYPSO digital baseband

Unfortunately we cannot provide many details on the GSM chipset due to very tight NDA's. However, this is not neccessarily required, since it interfaces using a standard UART serial line with the S3C2410. On that interface, GSM 07.05, 07.10 and other standardized protocols are used.

TRF6151 RF Transceiver

Product Homepage: http://focus.ti.com/general/docs/wtbu/wtbuproductcontent.tsp?templateId=6123&navigationId=12296&contentId=4701

AGPS

Hammerhead AGPS from Global Locate.

microSD-Card

The Neo1973 has one microSD aka Transflash slot.

LCD Display Module (LCM)

This is a 2.8" 480x640 toppoly (tpo) TD028TTEC1 module, using a Toshiba JBT6K74 TFT LCD Driver Chipset.

Touch Screen

Bluetooth

Delta DFBM-CS320 Class2 Module, using CSR BlueCore4

Vibrator

USB Host

The USB Host controller is inside the S3C2410

  • Driver: Stock Linux kernel ohci_hcd

USB Device

The USB Device controller is inside the S3C2410

Audio

See also: Neo1973 Audio Subsystem

Wolfson Codec

There's a WM8753 Wolfson Microelectronics Codec.

Stereo Amplifier

There's a National Semiconductor LM4857 Stereo 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-fashined wired headsets.

The headsets used by Motorola smartphones (A780,A1200, ...) have a compatible configuration

Bluetooth Headset

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

Power Management

A Philips PCF50606 is used for power management.

History

GTA01

This is the most simple, non-bluetooth version of the prototype.

GTA01v3

First generation of prototypes that was given to internal OpenMoko software developers.

Unfortunately not useful at all due to non-working touchscreen.

  • ATAG_REVISION: 0x0000130

GTA01v4

Second generation of prototypes that was given to Harald + Mickey.

Unfortunately still not useful due to half-working touchscreen.

  • ATAG_REVISION: 0x00000140

GTA01B

This is the bluetooth-enabled fork of GTA01

GTA01Bv2

This is the first produced version of the bluetooth-enabled version.

  • ATAG_REVISION: 0x00000220

GTA01Bv3

This is the second produced version of the bluetooth-enabled version. It contains mainly GPS-related fixes.

  • ATAG_REVISION: 0x00000230

This is the version that is shipped in Phase 0

GTA01Bv4

This is the version that is shipped in Phase 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.
