Your Peek must remain active during the processing of each command so you may need to move the scroll wheel or press a button intermittently during the process to keep it on. You must also have the Peek cable and Peek upgrade software installed on your computer before you start.
 +
 
 +
Power on Peek and connect Peek to PC using the Peek Upgrade cable. Determine wich port the Peek is connected to. Either Check Device Manager - Start > Run > devmgmt.msc OR right click My Computer > Properties > Hardware Tab and Look at LPT&COMM, expand + sign and you should see what COMM port your cable is on
 +
 
 +
Open a command prompt. If you plan on copying files to the computer you must right click "Command prompt" and run it as an administrator even if you are already logged on as an administrator. It should be located under "Accessories" in the start menu.

The Device

In The News

Basic Specifications

  • 320x240 TFT LCD with backlight
  • 47 Key QWERTY keyboard
  • 360 degree jogwheel with button
  • Vibrator Motor
  • Small Speaker
  • Side Push Button
  • Top Power Button
  • Standard SIM Socket
  • Micro-B USB Charging Socket ( USB connectivity is not supported, this is really just a TTL Serial port and a charging socket.)
  • Internal Coin Backup Battery
  • E-Mail Notification LED
  • Battery Door Contacts Switch

Discussions about the Current OS

  • It's a lightweight, purpose-built OS called PeekUX. [1]
    • Starts with TI's very own version of the real-time OS called Nucleus ( by Mentor )
    • TI has compiled in device drivers, and other stacks and turned it into their own platform.
    • Peek SW developers then took what TI gave them and wrap it with their own proprietary GUI and network libraries to create Peekux.
    • The email application then runs on top of that.
    • The whole thing is built as a single image. Thus the distinction between OS and App is blurred.
  • "Hacking maybe difficult" article at Peek Forums. [2]

Wireless Network and FCC stuff

  • Uses T-Mobile's nationwide GSM network.
  • Also can use AT&T's GSM network as a secondary network.
  • FCC ID is listed as: V6LPEEK0001
  • Uses the GSM850 band. TX: 824-848MHz RX: 869-893MHz
  • Maximum RF Radiated Power (GPRS850): 26dBm EIRP
  • RX Sensitivity: -109dBm ?
  • Antenna: PIFA type

Mail Handling

  • Currently, the very large computing resources at Amazon AWS (Seattle, WA) is being used to handle the mail polling and forwarding for the Peek users. The mail handler was worked out at Peek HQ and then unleashed at AWS. AWS's "EC2 Service" is immensely flexible and allows Peek to keep up with the growing user base.

Chip List

  • Spansion 71NS128NB0BJWRN 32Mb Psram + 128Mb NOR Flash datasheet Additional flash info
  • TI D6591BQA - TCS2310 - The original TI link is dead, but there's a snapshot on the Internet Archive
  • TI T3031FZH - TWL3031 power management and IO control
  • RFMD RF7115 Quad Band GSM850/GSM900/DCS/PCS TRANSMIT MODULE datasheet
  • ST STMPE2401 - Port expander with Keypad and PWM controller Datasheet
  • 26.00 MHz XTAL for the TCS2310
  • 32.768 kHz XTAL for the TWL3031

Battery

  • Model: PK-BAT-001
  • Voltage: 3.7V
  • Capacity: 700mAh
  • Maximum Charge Voltage:4.2V
  • Standard: GB/T18287-2000

Peek Accessories

  • Upgrade Cable for upgrade/hacking (No longer available).
  • Replacement Battery (No longer available).

Opening the Case

  • The case has 4 tiny "torx" style screws. The size is T6. You will need a Precision Torx Screwdriver set.
  • Obviously, opening your Peek voids the warranty.
  • There are 3 tiny screws immediately visible when you take off battery cover. And the fourth screw is hidden under the red "Do not remove" sticker.
  • After the screws are removed, start from bottom of unit and carefully pry the top and bottom housings apart.
  • To understand what I mean, see this picture from Maushammer on Flickr. On the left side of image is the bottom housing. Notice the four screw holes. The rest of the housing attaches with tabs that easily pry apart.

Debugging/Programming Tools

External MicroUSB Charge/Upgrade port

This is the MicroUSB port that is exposed on the left side of the peek.
It's used for both charging and upgrading the Peek. The upgrade cable uses
a serial TTL to USB level shifter to convert the serial TTL into a USB com port.
a bootlog can be viewed using serial settings 115200,n,8,1

Pin Function
1 +5V(USB Standard)
2 TXD +1.8V TTL
3 RXD +1.8V TTL
4 N/C
5 GND
Shield Drain wire

Internal UART Header

This is on the inside of the Peek under the SIM (this is also covered by the warranty sticker).
a bootlog can be viewed using serial settings 115200,n,8,1
Note: This is not a new, hidden serial port. This port is electrically the same as the External Charger/Upgrade port shown above.

Pin Function
1 Ground
2 nPowerButton (active low)
3 UART_RX +1.8V TTL (input to Peek)
4 USB_PWR +5V
5 UART_TX +1.8V TTL (output from Peek)
6 Bat+ 4.2V

Picture from Maushammer on Flickr

JTAG Pads (vias)

These vias are found on the bottom side of printed circuit board just below the white antenna strip.
*Note: You will need to remove the solder mask and solder small wire to the vias. 26AWG or 30AWG is best.
Obviously, the four signals TDO, TMS, TCK, and TDI are the most important ones. Connect these signals straight to your JTAG dongle.
You should also pick up a Ground signal somewhere near the DC Power circuity on the lower left section of PCB.
Perhaps, depending on your JTAG dongle, you could also power the Peek from the dongle itself.  ;-)

Thanks to "codeman" and "prpplague" for this (these pinouts may be wrong!).

uClinux

Bootloader

  • a bootloader, such as U-Boot or APEX, will be needed to facilitate booting uClinux
  • low level access to Flash memory via JTAG is now doable. ( see above )
  • U-Boot could be used, but is pretty large
  • APEX is small, configurable, and easily adapted for ARM7TDMI

Kernel

Root Filesystem

Tools

  • use CSST ( Cellular Systems Software Tools ) from TI for loading Flash with bootloader etc. This is the Release Notes for the CSST included in SDP2430 (OMAP2430). There is a CSST for the TI LoCosto chips included with the Peek Upgrader software from Peek. More detailed info on CSST can be found here.

The Peek update program calls a command line CSST app to actually load the new firmware to flash. In my case, the command line was:

 D:\apps\Peek\CSST\csstcli.exe -t 1 -op download -i D:\apps\Peek\software\Rel_01_09_10.m0 -dt NOR -p COM5 
This command can be executed from a command prompt. You will be prompted to reset the Peek (remove and replace the battery, then hit the power button) and the download will begin!
  • use TMSH to execute commands on the Peek itself (source):

Your Peek must remain active during the processing of each command so you may need to move the scroll wheel or press a button intermittently during the process to keep it on. You must also have the Peek cable and Peek upgrade software installed on your computer before you start.

Power on Peek and connect Peek to PC using the Peek Upgrade cable. Determine wich port the Peek is connected to. Either Check Device Manager - Start > Run > devmgmt.msc OR right click My Computer > Properties > Hardware Tab and Look at LPT&COMM, expand + sign and you should see what COMM port your cable is on

Open a command prompt. If you plan on copying files to the computer you must right click "Command prompt" and run it as an administrator even if you are already logged on as an administrator. It should be located under "Accessories" in the start menu.

Type in:

cd "C:\Program Files (x86)\Peek.1.10.00\tmsh" (or whatever your Peek directory is called)

Then type:

tmsh -psX -ttlocosto

Where X = your COMM port # from earlier.

Here's a list of TMSH commands:

Command Description
help Print help for the command name on stdout Arguments
run Run the script file named filename. Arguments
use Load the ETM module represented by the DLL “name.dll” Arguments
ping ping target Arguments [options]
