2 Formatting a Bootable SD Card
The OMAP35x processor supports booting from SD and several procedures in this document
walk you through a process using a bootable SD card. This section describes how to format an
SD card so the OMAP35x Torpedo Development Kit will recognize it as a bootable device.
A requirement of the OMAP35x processor is that the SD card must be formatted without an
extended partition to boot properly. The built-in Windows formatting tool is not always able to do
this. It has been found that the HP USB Formatting Tool version 2.0.6 appears to be the best tool
for formatting an SD card so it can be used to boot an OMAP35x device. NOTE: If you are using
Linux or have access to a Linux box, you can find instructions on the Texas Instruments (TI)
SD/MMC format for OMAP3 boot2wiki page.
The most recent version of the tool available on HP's site doesn't seem to work as well as version
2.0.6. As such, the tool needs to be downloaded from any number of third-party websites. To find
these websites, perform a Google search for: HP formatting tool 2.0.6. NOTE: As with
downloading anything from the Internet, use caution in what sites you visit and what you
download. Logic PD has no association with any of these websites and makes no guarantees to
their validity or the usability of downloads from their sites.
1. After the HP USB formatting tool has been installed on your host PC, insert an SD card into
your USB card reader and open the formatting tool. IMPORTANT: Remember that formatting
an SD card will erase its entire contents; back-up the SD card’s contents before continuing or
select a card that doesn’t contain vital information.

2. Select the SD card device and FAT32 from the File System drop-down menu. Click Start.
3. You will receive a warning that the contents of the card will be erased. Assuming you have
backed-up the contents of the SD card, click Yes.

4. When formatting completes, you will receive a confirmation screen with the new file system
type and the space allocation on the card similar to the window shown below.
You are now ready to add LogicLoader files (see Section 3) or the NAND flash recovery files
(see Section 4) to the SD card and boot from SD.

3 Update LogicLoader
This section will walk you through the process of updating the LogicLoader bootloader software
on your OMAP35x Torpedo SOM.
3.1 Terminal Emulation Installation
The Zoom OMAP35x Torpedo Development Kit is designed to communicate with terminal
emulation programs using the included null-modem serial cable. The terminal emulation program
must support binary transfers in order to download software to the kit. Although Logic PD does
not support any particular terminal emulation program, we suggest using Tera Term for Windows
2000 or XP (Tera Term is not available for Linux users). Tera Term can be downloaded for free
from Logic PD’s website. To install Tera Term:
1. Download the ZIP file3from Logic PD’s website and extract the contents.
2. After extracting the contents, locate the teraterm-x.xx.exe file and double-click it.
3. Follow the on-screen instructions to install Tera Term.
3.2 Setup Tera Term
All Tera Term settings are controlled by an .ini file that you can modify as needed to make your
time in Tera Term as efficient as possible (for example you can preset the port settings).
1. Start the Tera Term program
2. From the menu, select Setup > Serial port

5 Using Displays with the Torpedo Development Kit
When using displays with the OMAP35x Torpedo Development Kit, the JP1 jumper must be set
for the proper voltage source. JP1 selects the power source (5V or battery) for the LCD backlight.
Running the backlight off the battery will affect the charging rate; for this reason, only place JP1
across pins 2–3 when running off the battery alone. Anytime the 5V power supply is being used,
JP1 should be placed across pins 1–2.
