SDRAM

128MB SDRAM (64MB inside 2442 MCP, 1x Samsung K4M51323PC) attached to S3C2442 SDRAM controller

GSM/GPRS

The GSM (including GPRS) modem is Texas Instruments Calypso based and supports 2.5G tri-band GPRS/GSM. The two available models support either the 850/1800/1900 MHz bands (suitable for USA), or 900/1800/1900 MHz band (suitable for rest of the world).

CALYPSO ASIC 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.

The NDAd documentation for the calypso, register definition and hardware definition was leaked onto a public forum on the 4th of March by persons or persons unknown. The legality of reading these files may vary according to your local laws, as may generating code from them.

LCD Module (LCM)

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

Touch Screen

Bluetooth Module

Delta DFBM-CS320 Class2 Module, using CSR BlueCore4

Bluetooth Audio

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

WiFi Module

Accton (WLAN 802.11b/g SiP-M WM3236AQ(Flash Ver:2.0 Atheros AR6001GZ)

Vibrator

USB Host

The USB Host controller is inside the S3C2442

  • Driver: Stock Linux kernel ohci_hcd
  • USB version 1.1
  • Supply USB 5v in Host mode using usb power switch AAT1275IRN-5.0-T1
  • A net EN_USBHOST is controlled by PMU GPIO "GPO", this one signal when asserted (high)
    • enables generation of 5V for external device using a charge pump
    • enables connection of 15K pulldowns to D+ and D- to allow device insertion and removal detection for host mode
    • DISABLES the path for USB power to charge the battery

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 be powered and charging the battery if present at the same time. This method is called the Y-cable and was invented by Joerg Reisenweber. For additional info and circuit diagrams see Specialized USB Cables.

  • Connect 0V, 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 0V, +5 to your >1A power source
    • If your power source was not the Openmoko 1A charger, additionally connect a 47K ohm 5% resistor between the ID pin and ground to pretend to be the 1A charger.

In addition you need to make sure EN_USBHOST signal that enables the physical Host mode power generation and disables the USB -> PMU charging path is deasserted. This may be taken care of automatically shortly by detection of the 48K resistor on a USB insertion leading to forcing EN_USBHOST deasserted. The charge pump that generates the 5V in host mode doesn't seem to mind getting external 5V given to it, but the real issue is that the battery will not be charged at all if we leave EN_USBHOST asserted since one of its jobs is to stop that happening.

USB Device

The USB Device controller is inside the S3C2442

I2C Devices

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

Distinguishing hardware revisions

Inside the Bootloader

Mass production devices (A5 and later)

The bootloader reads the hardware revision from the PCB.[3]

Prototypes (A4 and earlier)

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

Mass production devices (A5 and later)

The kernel reads the hardware revision from the PCB.[4]

Prototypes (A4 and earlier)

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.

SDRAM

128MB SDRAM (64MB inside 2442 MCP, 1x Samsung K4M51323PC) attached to S3C2442 SDRAM controller

GSM/GPRS

The GSM (including GPRS) modem is Texas Instruments Calypso based and supports 2.5G tri-band GPRS/GSM. The two available models support either the 850/1800/1900 MHz bands (suitable for USA), or 900/1800/1900 MHz band (suitable for rest of the world).

CALYPSO ASIC 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.

The NDAd documentation for the calypso, register definition and hardware definition was leaked onto a public forum on the 4th of March by persons or persons unknown. The legality of reading these files may vary according to your local laws, as may generating code from them.

USB Host

The USB Host controller is inside the S3C2442

  • Driver: Stock Linux kernel ohci_hcd
  • USB version 1.1
  • Supply USB 5v in Host mode using usb power switch AAT1275IRN-5.0-T1
  • A net EN_USBHOST is controlled by PMU GPIO "GPO", this one signal when asserted (high)
    • enables generation of 5V for external device using a charge pump
    • enables connection of 15K pulldowns to D+ and D- to allow device insertion and removal detection for host mode
    • DISABLES the path for USB power to charge the battery

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 be powered and charging the battery if present at the same time. This method is called the Y-cable and was invented by Joerg Reisenweber. For additional info and circuit diagrams see Specialized USB Cables.

  • Connect 0V, 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 0V, +5 to your >1A power source
    • If your power source was not the Openmoko 1A charger, additionally connect a 47K ohm 5% resistor between the ID pin and ground to pretend to be the 1A charger.

In addition you need to make sure EN_USBHOST signal that enables the physical Host mode power generation and disables the USB -> PMU charging path is deasserted. This may be taken care of automatically shortly by detection of the 48K resistor on a USB insertion leading to forcing EN_USBHOST deasserted. The charge pump that generates the 5V in host mode doesn't seem to mind getting external 5V given to it, but the real issue is that the battery will not be charged at all if we leave EN_USBHOST asserted since one of its jobs is to stop that happening.

USB Device

The USB Device controller is inside the S3C2442

I2C Devices

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

  • Product Homepage: LM4853.html
  • Data Sheet: LM4853.pdf
  • Connects to (LM4853 pin):
    • S3C2442 GPIO: HP_IN, AMP_SHUT (shutdown);
    • Wolfson WM8753: LOUTL (LEFTIN), LOUTR (RIGHTIN);
    • speaker4102: (LEFTOUT/BLTOUT-, BLTOUT+);
    • headset-jack: ring 2 (RIGHTOUT), ring 3 (LEFTOUT/BLTOUT-) via 1uF-33R each

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, as does the headset for an LG muziq 570.

Case

The case for the FreeRunner is all black, as seen on the front page of the wiki.

Openmoko has released the CAD files for the case of the Neo1973 and Neo FreeRunner. These were created using Pro/ENGINEER (also called Pro/E). They are available in the Pro/E (.asm/.prt) format, but alternative formats are also available.


We welcome your assistance in providing other formats. If you are able to convert CAD files from Pro/E format to other formats, please contact [1]. We are especially interested in the DXF format and in images rendered from these files.

Distinguishing hardware revisions

Inside the Bootloader

Mass production devices (A5 and later)

The bootloader reads the hardware revision from the PCB.[3]

Prototypes (A4 and earlier)

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

Mass production devices (A5 and later)

The kernel reads the hardware revision from the PCB.[4]

Prototypes (A4 and earlier)

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.
