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.

Wolfson Codec

Main article: WM8753

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.

Pinout: [5]

base = ground 
speaker left  (internal impedance 33R) to ground. (+jackinsert detection)
speaker right (internal impedance 33R) to ground.
tip = mic electret condenser type, to ground. 
      bias (power for mic) 2K2 from +3.3v(wolfson codec) 
      (+HoldButton shortcircuit to ground)

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

Alternate cases

A number of alternate case designs have been suggested and requested.

  • GSM_EN - R1501 (not present) - ungrounded end

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.

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

Hardware        : GTA01
Revision        : 0240

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.
