Kit Contents
The LAUNCHXL-F28379D LaunchPad kit includes the following items:
• C2000 Delfino LaunchPad Board (LAUNCHXL-F28379D)
• Mini USB-B Cable, 0.5m
• Quick Start Guide
2.1
Revisions
The first production revision of the LAUNCHXL-F28379D in 2016 was Revision 1.1. In late 2017 the
LAUNCHXL-F28379D revision changed from 1.1 to 2.0 to fix various issues and make improvements to
the design.
All Revisions:
• Resistor R7 in the oscillator circuit is incorrectly placed or should not be installed. This resistor may
impact startup time or robustness of the clocking circuit over the full operating range of the MCU or
different physical layouts of this circuit. The probability is low that this resistor will have any impact on
the functionality of this EVM as is not intended to be operated outside of Standard Temperature and
Pressure in a lab or prototype environment. Do not use this circuit as reference. Follow the
requirements for the Oscillator schematic as documented in the MCU Datasheet.
• The SCIA pins routed to the XDS100 v2 are not valid SCI boot mode pins. In addition, the other bootable SCI pins are not routed to any external connector. In other words, this LaunchPad is not capable
of using the Boot to SCI boot mode. The TMDSCNCD28379D can be used to evaluate this feature.
Revision 1.1:
• ADCINA2 is shorted to VREFHIB. It is recommended that users avoid using the ADCINA2 channel.
• The VIN+ signal of component U1 may be shorted to ADCINB4 and/or ADCINC4 due to variance in
manufacturing tolerances. No issues have been reported, but the clearances violate manufacturing
rules and a short may occur.
• The silkscreen for the ADC channels on J3 and J7 are mixed up and some may be incorrect.
Reference the schematic for the proper pin positions.

J3 and J7 connectors are labeled incorrectly on the backside silkscreen. Refer the Rev 1.1 schematic
for the proper signal locations on the connector
Revision 2.0:
A revision was made to resolve the layout issues present on revisions 1.1. In addition to the fixes for
aforementioned issues, additional changes were made to the schematic and layout to improve available
features and increase usability.
• User LEDs and current limiting resistor values were changed to prevent the LEDs from being too bright
to look at directly.
• The CAN signal header J12 was shifted towards the center of the board and the silkscreen properly
aligned. PGND was removed and replaced with GND for the proper grounding of the CAN signals.
• J11 and J13 were removed and replaced with a 0Ω resistor selection tree for routing between the
BoosterPack headers and the backside high-density connector J9. For more information on how to
configure these resistors for the desired routing, see Section 5.5.
• Additional EMIF1 signals were routed to J9 to enable SDRAM support. These signals are also routed
to the BoosterPack headers. As such, these signals have a resistor selection network for routing the
signals to either the BoosterPack headers, J9 or both. For the information on how to configure these
resistors for the desired routing, see Section 5.5.
• An additional jumper, J16, was added to the lower left corner of the board for an additional connection
point for supplying +5 V externally.
• ADC input signal conditioning circuit was updated for proper operation under additional operating
conditions. C4 is now 180 pF; R60/R61 are changed to 10k-Ω and are placed between the VOUT
signal of U13 to the VOCM of U1.
• Backside silkscreen for J3 and J7 have been corrected and reflect the proper signals at the noted
location on the connector.

Getting Started With the LAUNCHXL-F28379D
4.1
Getting Started
The first time the LAUNCHXL-F28379D board is powered-on a demo application will automatically start.
Connect the LAUNCHXL-F28379D to a free USB port using the included mini-USB cable. The demo
application will start with LEDs D9 and D10 blinking to show the device is active. If your board does not
start the demo application, try setting switch S1 in the following positions and resetting the board: 1-UP, 2UP, 3-DOWN.
4.2
Demo Application, ADC Sampling
The LAUNCHXL-F28379D includes a pre-programmed TMS320F28379D device. When the LaunchPad is
powered via USB, the demo starts with an LED blink sequence. After a few seconds the device switches
into an ADC sample mode.
Every 1 second the ADC samples pin ADCIN14 and the sampled data is represented as follows: If the
sample is above mid-scale (2048), the blue LED D10 will illuminate. If the sample is below mid-scale, the
red LED D9 will illuminate.
In addition to the LED indicators, ADC sample information is also displayed on your PC through the
USB/UART connection. To view the UART information on your PC, first determine the COM port
associated with the LaunchPad. To do this in Windows, right click on My Computer and click on
Properties. In the dialog box that appears, click on the Hardware tab and open Device Manager. Look for
an entry under Ports (COM & LPT) titled "USB Serial Port (COMX)", where X is a number. Remember this
number for when you open a serial terminal. The demo applications UART data was written and debugged
using PuTTY, and for the best user experience we recommend you use PuTTY to view the UART data.
PuTTY can be downloaded from the following URL:
http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
Open your serial terminal program and open the COM port you found previously in device manager with
the following settings: 115200 Baud, 8 data bits, no parity, 1 stop bit. After opening the serial port in your
serial terminal, reset the LaunchPad with the reset push button S3 and observe the serial terminal to see
the TI logo in ASCII art.
4.3
Program and Debug the ADC Sample Demo Application
The project and associated source code for the C2000 Delfino LaunchPad demo is included in the
C2000Ware software package and should automatically be found by the TI Resource Explorer in Code
Composer Studio. In the resource explorer, navigate C2000Ware to find the
device_support\f2837xd\examples folder. Expand this item and LAUNCHXL-F28379D, then select the
LaunchPad Demo Application. Follow the steps in the main pane of the resource explorer to import, build,
debug, and run this application.
4.4
Using Other C2000Ware Examples
Including the LaunchPad demo example described above, C2000Ware provides many examples
demonstrating a majority of the features of the F2837x MCU. Most examples are configured by default to
use the TMDSCNDC28379D ControlCARD, which has a different on-board clocking circuit. As such, some
examples may not work as intended without minor modification. To make this easier on the designer,
compiler switch has been added to automatically pick the proper clock configuration based on adding
"_LAUNCHXL_F28379D" as a predefined symbol in the project properties. Refer to Section 8for more
information on how and where to define this symbol.

Hardware Configuration
The F28379D LaunchPad provides users with several options for configuring the board.

Hardware Configuration
5.1
www.ti.com
ADC Resolution
The F28379D had 4 independent 16-bit/12-bit ADCs. The resolution of each ADC is SW selectable.
ADCA, ADCB, and ADCC are all routed to the BoosterPack headers for use with different booster packs.
Most BoosterPacks will use the ADC in 12-bit mode which supports Single Ended (SE) inputs. ADCD has
been routed to a special side connector with ability to drive through a differential amplifier to support 16-bit
mode with Differential Ended (DE) inputs.
5.2
Power Domain
The LaunchPad has several different power domains to enable JTAG Isolation. Jumpers JP1, JP2, JP3
control JTAG Isolation, supply GND, 3.3 V and 5 V to the rest of the board. There are also other jumpers
that provide different methods for powering the device.
Table 1 describes the different methods by which 3.3 V can be supplied to the device. It can be derived
from USB in configuration 1. Here, the on-board regulator steps the 5 V from the USB port down to 3.3 V
to be used by the XDS100v2 debug probe as well as connected to the device side of the LaunchPad
through JP1. Configuration 1 is a non-isolated configuration. Alternately, in configuration 2 the debugger
and USB connection are isolated from the device. The 3.3 V source must be provided externally through
the BoosterPack headers or through J10.

The LaunchPad also has a 5 V power rail. It can be supplied directly from the USB (not isolated)
generated from a 3.3 V to 5 V step-up regulator through JP6, or supplied externally through the
BoosterPack Headers or J16. Table 2 describes these various configurations.
The debug probe and USB are not isolated in configuration 1 since JP2 and JP3 are connected. The 5 V
supply is coming from the USB directly to the device side of the LaunchPad and can be used to power
other devices connected to the BoosterPack headers. In this configuration, do not connect JP6 as there
may be contention between the 5 V from the USB (JP3) and the 5 V from the on-board step-up regulator,
U12.
Configuration 2 is an isolated configuration where 3.3 V is supplied any way other than through JP1. In
this configuration, JP6 is connected allowing the 3.3 V to be stepped up to 5 V with the on-board step-up
regulator, U12. In this configuration ensure that no other 5 V source is connected to the BoosterPack
headers or through J16.
Configuration 3 is another isolated configuration since JP2 and JP3 are not connected. With JP6
disconnected, 5 V must be supplied through an external connection on the BoosterPack headers or J16.
Notice that this configuration does not rely on the 3.3 V supply being powered to provide the 5 V. To
supply 3.3 V to the device in an isolated configuration, see Table 1.

Boot Mode Selection
The LaunchPad's F28379D device includes a boot ROM that performs some basic start-up checks and
allows for the device to boot in many different ways. Most users will either want to perform an emulation
boot or a boot to flash (if they are running the application standalone). Switch S1 has been provided to
allow users to easily configure the pins that the bootROM checks to make this decision. The positions on
S1 correspond to those shown in Table 3.

TRSTn
Keep in mind that the debug probe does not connect if the device is not in the emulation boot mode
(TRST switch in the UP-1 position). More information about boot mode selection can be found in the Boot
ROM section of the TMS320F2837xD Dual-Core Delfino Microcontrollers Technical Reference Manual.
5.4
Connecting a BoosterPack
The F2837xD LaunchPad is the perfect experimenter board to start hardware development with the
F2837xD devices. All of the connectors are aligned in a 0.1-in (2.54-mm) grid to allow easy and
inexpensive development of add on boards called BoosterPacks. These satellite boards can access all of
the GPIO and analog signals. The pinout of the connectors can be found in Section 5.
5.5
GPIO Routing Between BoosterPack and I/O Expansion Headers
This LaunchPad has a high-density connector (J9) on the backside of the board. This connector provides
for an IO expansion board to be connected. Many of the EMIF1 signals are available as well as SPI and
I2C. Some of the signals present on J9 are also available on the BoosterPack expansion headers.
On Revision 1.x LaunchPads, only two signals were dual-mapped to both J9 and the BoosterPack
Headers, GPIO40 and GPIO41. To select the destination, the three-position jumpers, J11 and J13, could
be adjusted accordingly. Placing the jumper between position 1 and position 2 will route the signal to J9.
Placing the jumper between position 2 and position 3 will route the signal to the BoosterPack headers.
On revision 2.0 LaunchPads, in addition to GPIO40 and GPIO41, four more signals may be routed to
either the BoosterPack headers or J9 independently, or may be connected to both based on the
placement of 0Ω resistors. By default, the signals are only routed to the BoosterPack headers for
alignment with the BoosterPack standards. Table 4 provides the mapping for each signal and which
resistors populate in order to route the signal as desired. Refer to the schematic at the end of this
document in Section 6.2,or located in the C2000Ware directory.

Frequently Asked Questions (FAQ)

Frequently Asked Questions (FAQ)
1. Can other programming and debug tools (such as an XDS510 debug probe) be used with the C2000
LaunchPad?
While a user could potentially connect an external debug probe to the F28379D device present on the
LaunchPad, it would require some rework of the board. It is recommended that users who want to use
an external debug probe, purchase a controlCard and docking station that includes an external JTAG
connector.
2. What versions of Code Composer Studio can be used to develop software for the C2000 LaunchPad?
It is highly recommend that novice users develop applications with at least Code Composer Studio v6.
The drivers, examples, and other associated software are tailored to make the user experience as
smooth as possible in Code Composer Studio v6.
3. Why can’t I connect to the LaunchPad in Code Composer Studio?
There are a number of things that could cause this and they all have an easy fix.
• Is S1 switch 3 in the down position?
This is the TRST pin that enables and disables JTAG functionality on the chip. This switch must be
in the up position for the debug probe to be able to connect.
• Are both power LEDs lit?
The board has two power domains because of the isolated JTAG interface. For low-voltage
application development, JTAG isolation is not needed and the power domains can be combined to
allow for convenience (that is, the board can be powered completely through the USB). Ensure that
jumpers are placed on the posts of JP1 and JP2.
• Are drivers correctly installed for the XDS100v2 present on the LaunchPad?
Right click on My Computer and select properties. Navigate to the Hardware tab in the dialog box
and open the device manager. Scroll to the bottom of the list and expand the USB Serial Bus
controllers item. Are there two entries for TI XDS100 Channel A/B? If not, try unplugging and
replugging in the board. Does Windows give you any messages in the system tray? In Device
Manger, do either of the entries have a yellow exclamation mark over their icon? If so, try
reinstalling the drivers.
4. Why is the serial connection not working?
• Are you using the correct COM port?
Right click on My Computer and select properties. Navigate to the Hardware tab in the dialog box
and open the device manager. Scroll to Ports (COM & LPT) and expand this entry. Is there a USB
Serial Port listed? If so, read the COM number to the right of the entry; this is the COM number you
should be using.
• Are you using the correct baud rate?
Most, if not all, of the examples are configured for a baud rate of 115200 when the CPU is running
at 200 MHz. If you have changed the PLL settings or written your own application you may have to
recalculate the baud rate for your specific application. For information on how to do this, see the
TMS320F2837xD Delfino Microcontrollers Technical Reference Guide.
5. Why is my program operating at half the frequency of what I expected?
• By default many of the C2000Ware examples are configured to operate on the
TMDSCNCD28379D which has a different clocking circuit, where the external clock is 20 MHz
instead of 10 MHz as found on this EVM.
• A compiler switch was added to various functions to allow a user to change the clocking
configuration based on the status of a predefined symbol.
• To ensure the PLL is correctly configured for the LAUNCHXL-F28379D, Add
"_LAUNCHXL_F28379D" to the predefined symbols list.
• Access the Predefined symbols list by accessing the Project Properties, Navigating to Build »
C2000 Compiler » Advanced Options » Predefined Symbols. Figure 22 shows the Project
Properties selection tree and the symbol added to the pre-define list.
