+
 
+
===== GTA01Bv3 Errata =====
+
====== PMU unable to resume from suspend ======
+
Due to use of wrong GPIO/EINT pin, the PMU cannot wake-up the phone after suspend.  This means, specifically, '''the following events can not bring the phone back from suspend-to-ram''':
+
* PMU RTC Alarm
+
* Power button press
+
* Charger events (charger insertion/removal/error)
+
* Low battery
+
 
+
====== Stand-by time extremely low ======
+
This is due to a design bug resulting in at least 30mA additional standby current, since we cannot properly switch off the power supply to the S3C2410 PLL's.  There is nothing we can do to change this with post-production fixes.  GTA01Bv4 will address this issue.
+
 
+
====== GSM doesn't resume phone from suspend ======
+
The GSM modem currently doesn't signalize a wakeup interrupt to the S3C2410 in case there's some noteworthy event, such as incoming call, loss of network, incoming SMS or the like.
+
 
+
This is a serious issue, but can be fixed with a GSM Modem Firmware update.
+
 
+
====== GSM Sidetone too loud ======
+
The local feedback sidetone (see [http://en.wikipedia.org/wiki/Sidetone]) is too loud.  This will be addressed in a GSM firmware update
+
 
+
====== Bad block ======
+
Due to an error in the production process, the factory-programmed NAND bad block information has been lost.  This means that some blocks in the flash will wear out rapidly, which might become as bad as rendering the device unusable.
+
 
+
==== GTA01Bv4 ====
+
This is the version that will be shipped in Phase 1
+
 
+
===== Changes from GTA01Bv3 =====
+
# Fix all Errata items from GTA01Bv3
+
# Add I2C, SPI and one irq and wakeup capable GPIO pin to debug port plus have test pads for all these signals (for soldering wires directly on the pcb)
+
# Fix a number of production related details and minor hardware details that are not user-visible

Neo 1973
sold out

(Other phones)

Openmoko is a software distribution stack that sits on top of a hardware platform. The Neo1973 phone is the first hardware platform to take advantage of Openmoko. You can find specifics of the Neo1973 Hardware by reviewing this introduction page and the pages in the category as shown at the bottom of this page.

Note that this page is about the first Openmoko phone which is now discontinued. See details on the second Openmoko phone at this page - Neo FreeRunner GTA02 Hardware.

[edit] Distinguishing hardware revisions

[edit] Inside the U-Boot

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

[edit] Inside the Kernel

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

[edit] From Userspace

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

??? So does GTA01Bv4 equal the cat /proc/cpuinfo output of

Hardware        : GTA01
Revision        : 0240

[edit] Approval

  • CE compliance is needed before a product can be sold in the EU. The CE mark indicates that a product complies to the relevant legislation, defined in the harmonised standards. This refers also to the most relevant, for the Neo1973, Directive 89/336/EEC on electromagnetic compatibility (EMC is the art of assuring electromagnetic compatibility between products). The standards are defined by CENELEC (European Committee for Electrotechnical Standardization), but not verified by any authority. It is the responsibilty of the manufacturer to convince himself that a product is in compliance, and is obligated to be able to prove this (with relevant technical documentation) for a specific product to the authorities on request. Whether the current Phase 1 devices are actually tested against the directives are unknown, no documentation has been disclosed, other than the fact that the devices bear the CE mark.

  • 184 +/- 5 g (6.5 ounces)

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 NDAs. However, this is not neccessarily required, since it interfaces using a standard UART serial line with the S3C2410. On that interface, GSM 07.05, GSM 07.10 and other standardized protocols are used.

-- xkr47: Could we at least know the GPRS capabilitiy class and the GPRS multislot class ?

TWL3014 analog baseband

Key Features:

Single-chip transceiver with quad-band support
Direct conversion architecture
GPRS Class12/CS4 compliant
Full integration of VCO and VCO tanks
Integrated voltage regulators, PA control loop, PLL loop filters and VCXO
N-fractional synthesizer
7 mm x 7 mm, 48-pin QFP package

AGPS

Hammerhead AGPS from Global Locate.

This will not have a working driver till at least mid April.

microSD-Card

The Neo1973 has one microSD aka Transflash slot. It should support SDHC, but this has not been tested. If this works, cards >2G should work with no problems. As there are no microSD cards over 2G at the moment, it hasn't been tested. MicroSD slot is under battery.

LCD Display Module (LCM)

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

Audio

See also: Neo1973 Audio Subsystem

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'.

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-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.

Power Management

A Philips PCF50606 is used for power management.

Battery

The Neo1973 Battery is compatible with a Nokia BL5C battery. According to this post on the mailinglist. Photo of the battery inside the Neo1973.

Buttons

The Neo1973 features two buttons:

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

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

GTA01Bv3 Errata
PMU unable to resume from suspend

Due to use of wrong GPIO/EINT pin, the PMU cannot wake-up the phone after suspend. This means, specifically, the following events can not bring the phone back from suspend-to-ram:

  • PMU RTC Alarm
  • Power button press
  • Charger events (charger insertion/removal/error)
  • Low battery
Stand-by time extremely low

This is due to a design bug resulting in at least 30mA additional standby current, since we cannot properly switch off the power supply to the S3C2410 PLL's. There is nothing we can do to change this with post-production fixes. GTA01Bv4 will address this issue.

GSM doesn't resume phone from suspend

The GSM modem currently doesn't signalize a wakeup interrupt to the S3C2410 in case there's some noteworthy event, such as incoming call, loss of network, incoming SMS or the like.

This is a serious issue, but can be fixed with a GSM Modem Firmware update.

GSM Sidetone too loud

The local feedback sidetone (see [1]) is too loud. This will be addressed in a GSM firmware update

Bad block

Due to an error in the production process, the factory-programmed NAND bad block information has been lost. This means that some blocks in the flash will wear out rapidly, which might become as bad as rendering the device unusable.

GTA01Bv4

This is the version that will be shipped in Phase 1

Changes from GTA01Bv3
  1. Fix all Errata items from GTA01Bv3
  2. Add I2C, SPI and one irq and wakeup capable GPIO pin to debug port plus have test pads for all these signals (for soldering wires directly on the pcb)
  3. Fix a number of production related details and minor hardware details that are not user-visible
