2 Connect Development Kit to PC
In order to begin development work, the development kit needs to be connected to a host PC.
You can use either a serial cable (Section 2.1) or a USB mini-B cable (Section 2.2); both cables
are included in the development kit.
2.1 Connect Using Serial Cable
1. Connect the null-modem serial cable to the serial port connector on the baseboard and to an
empty COM port on your host PC. See Figure 2.1.
2. Connect the regulated 5V power supply to the appropriate power adapter for the location in
which you are using the development kit.
3. Plug the power adapter into an electrical outlet and the 5V line output connector into the
power-in connector on the baseboard. See Figure 2.1.
Figure 2.1: Connect Serial Cable
4. Before powering on your kit, you will have to install a terminal emulation program to
communicate with the development kit. Please proceed to Section 2.3 for details.
2.2 Connect Using USB Mini-B Cable
1. Connect the USB mini-B cable to the debug UART USB port on the baseboard and to an
empty USB port on your host PC. See Figure 2.2.
NOTE: The baseboard is equipped with an FTDI virtual COM port (VCP) chip that causes the
USB device to appear to your computer as an additional COM port. Settings for the terminal
emulation program will remain the same; however, a driver must be installed on your
computer for proper operation. A link to the driver and instructions for using the
USB-to-UART VCP chip can be found in Logic PD’s USB-to-UART VCP Chip Driver

Figure 2.2: Connect USB Mini-B Cable
4. Before powering on your kit, you will have to install a terminal emulation program to
communicate with the development kit. Please proceed to the next section for details.
2.3 Install Terminal Emulation Program
The Zoom DM3730 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
(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.
2.3.1 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.
3. Select the appropriate COM port for your workstation and then change the port settings to:
a. Baud rate: 115200
b. Data: 8 bit
c. Parity: None

4. Click OK.
2.4 Boot into LogicLoader
LogicLoader is a bootloader program created by Logic PD that provides the capability for loading
operating systems (OS) and applications. In addition, it provides a full suite of commands for
interfacing to the System on Module (SOM). These commands load OSs, configure hardware
platforms, bring up hardware, customize applications, perform tests, and manage in-field devices.
1. Make sure the development kit is set up as described in Section 2.1 or Section 2.2.
2. Remove the pre-built OS image SD card from the baseboard, if one is inserted. This step is
important because LogicLoader boots from onboard flash.
3. Start the terminal emulation program on your host PC.
4. Verify that the serial port settings are correct (see Figure 2.3 in the previous section).
5. Move the power switch to the ON position to boot the development kit.

3 Format a Bootable SD Card
The DM3730 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 Zoom DM3730 Torpedo Development Kit will recognize it as a bootable device.
A requirement of the 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.
Logic PD has 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 a processor based on OMAP3 technologies
(e.g., DM3730, AM3703). NOTE: If you are using Linux or have access to a Linux box, you can
find instructions in Texas Instruments’ (TI) SD/MMC format for OMAP3 boot wiki article.4
The most recent version of the tool available on HP's site does not 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 version 2.0.6 has been installed on your host PC, insert an
SD card into your USB card reader, connect the card reader to your host PC, and open the
formatting tool. IMPORTANT NOTE: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 4) to the SD card and boot from SD.

4 Update LogicLoader
1. Power on your kit and hold down the vkey on the keyboard. Doing this will provide specific
boot information in the LogicLoader output. For instance, in the image below, you see that the
image type is Elf and it booted from NAND. This is a helpful trick to use to determine if your
development kit is booting from the onboard NAND flash or the SD card.
2. Take note of what LogicLoader version number appears in this welcome prompt. This will
help you know if you need to upgrade to a new version.
3. Power off your kit.
4.1 Download New Version of LogicLoader
1. Log into Logic PD’s downloads page5using your username and password.
2. Click on the All Downloads link under the DM3730 Torpedo Development Kit heading.
3. Scroll down until you find the section header LogicLoader Bootloader/Monitor.
4. Click on the +icon next to the LogicLoader for DM3730 / AM3703 SOMs link; this expands
the list of all available LogicLoader versions. If the current version is newer than what is on
your DM3730 Torpedo SOM or DM3730 Torpedo + Wireless SOM, you should update.
5. Click on the version number marked (current) and save the file to your host PC.
6. After the ZIP file finishes downloading, extract all files of the folder to a location on your host
PC that you can access later on.
Now that you have downloaded the latest version of LogicLoader to your computer, you can
update LogicLoader on your development kit using a bootable SD card.

4.2 Update LogicLoader using a Bootable SD Card
1. Prepare a bootable SD card as described in Section 3.
2. Locate the LogicLoader files that you downloaded to your host PC in Section 4.1.
3. Copy the MLO file from that folder to the SD card. IMPORTANT NOTE: This file must be
the first added to the SD card for the kit to boot properly.
4. Next, copy the lboot.elf file to the SD card.
5. Remove the SD card from your USB card reader and insert it into the bootable SD card slot
on your Zoom DM3730 Torpedo Development Kit (see Section 1.3 for its location).
6. Slide the power switch to the ON position; you should see a screen similar to that shown
below. HINT:You can hold down the vkey on the keyboard during boot-up to verify the Boot
Device is SDMMC, indicating the kit booted from the SD card.
Notice that the LogicLoader Version number now shows the version you downloaded from
the Logic PD website. This is because you have booted from the SD card containing that
version.

7. Because NoLo and LogicLoader reside in NAND, it is necessary to erase the old LogicLoader
before updating to a new one. Type erase /dev/nand0 B0 B4096 and press Enter.
Because the kit was booted from SD, you will not be warned that you are erasing locked
areas in NAND. You now have a blank flash device to update to.
8. Type update and press Enter. Your screen should look similar to that included below.

9. LogicLoader is waiting for you to send the new version over the serial port. From the menu
toolbar, select File > Send file... to send the new LogicLoader version to your kit.
10. Navigate to the location where you extracted the LogicLoader files and select the file that
includes nolo_lolo_NAND.upd. This file contains both NoLo and LogicLoader components
necessary for updating LogicLoader. If you do not see a file that includes
nolo_lolo_NAND.upd, please refer to the Release_Notes.txt file included in the LogicLoader
version download for special instructions.
11. Verify that the “Binary” checkbox is checked. Click Open.
