  • 456-MHz ARM926EJ RISC CPU (OMAP-L138 only)
  • On-Chip RTC


  • 128 MByte DDR2 SDRAM running at 150MHz
  • 128 MByte 16-bit wide NAND FLASH
  • 1 Micro SD/MMC Slot


  • One mini-USB Serial Port (on-board serial to USB)
  • One Fast Ethernet Port (10/100 Mbps) with status LEDs
  • One USB Host port (USB 1.1)
  • One mini-USB OTG port (USB 2.0)
  • One SATA Port (3Gbps)
  • One VGA Port (15 pin D-SUB)
  • One LCD Port (Beagleboard XM connectors) 
  • One Composite Video Input (RCA Jack)
  • One Leopard Imaging Camera Sensor Input (36-pin ZIP connector)
  • Three AUDIO Ports (1 LINE IN & 1 LINE OUT & 1 MIC IN)
  • 14-pin JTAG header (No onboard emulator; external emulator is required)


  • The LCDK does not have an onboard emulator. An external emulator from TI or a third-party will be required to start developing on it.
  • The LCD port connector was designed to support off the shelf LCD panel that is no longer available from any vendor. We are not aware of any other off the shelf LCD panel that will work with LCDK. To evaluate an LCD panel using the LCDK board, will require users to create their own adapter board.
  • TI has released new versions of the OMAPL138 and C6748 LCDK boards. The new boards do not support the Authentec fingerprint swipe sensor. This decision is predicated upon Authentec’s decision to discontinue production of this sensor. TI has no plans to replace the sensor with an alternative solution at this time. The change is effective immediately. Any boards shipped from Dec 2012 will reflect this change. If you have placed an order that you want to review in light of this information, please contact the channel through which the order was placed. We apologize for any inconvenience this may cause.

Description Provide connectivity to CircuitCo ULCD7 Lite LCD

User Interface

Switches (SW1)

Switches 1-4 on SW1 are used to set the BOOT as follows:

Switch # UART2 NAND 16 MMC/SD0

Switches 5-8 on SW1 are user switches connected to GPIOs according to the table below. When the switch is ON, the pin is pulled low. When the switch is OFF, the pin is pulled high.

Switch # Pin
5 GPIO0[1]
6 GPIO0[2]
7 GPIO0[3]
8 GPIO0[4]

Push Buttons

There are 3 push buttons on the board connected according to the following table. When a button is pressed, the attached signal is pulled low; otherwise it is pulled high.

Button Pin
S1 Reset
S2 GPIO2[4]
S3 GPIO2[5]


There are 7 LEDs on the board which function according to the following table.

LED Signal Lit when...
D1 5V_IN 5V power is applied to J1
D2 VOLT_ERR Input voltage is > 5.8V
D3 VCC_5VD_IN Board is powered from either J1 or USB
D4 GPIO6[13] Signal is high
D5 GPIO6[12] Signal is high
D6 GPIO2[12] Signal is high
D7 GPIO0[9] Signal is high


The board can be powered with 5V input through either J1 barrel connector or through J2 mini-USB connector. Current draw for the board can exceed 500 mA under normal operating conditions, so it is not recommended to use the USB power.

USB UART Port (J3)

The board contains FD232 USB UART IC, which can be connected to a host PC via a standard mini-USB to USB cable, and it acts an external serial port. It is connected to the OMAP-L138/C6748 UART2 peripheral.

Windows and Linux drivers for the chip can be found on the FTDI Product Page.

Configure your serial terminal application (such as Tera Term or HyperTerminal) for 115200 baud, 8 data bits, 1 stop bit, no parity, choosing the COM port corresponding to the USB device:

AM18x OMAPL138 WinCE 6 0 BSP Quick Start Guide 01.png

In Windows, you can determine which COM port the USB serial port is using in Device Manager, as shown below:


Procedure to Flash and boot the LCDK

The NAND may be flashed either through the USB-serial port or through CCS. The following software provides both tools:

The following AISgen config file has the correct settings for NAND16 boot, with the CPU running at 300MHz, and DDR2 at 150MHz:

  • Serial Port Method

First determine what serial port is assigned to the on-board UART->USB IC as show in this section

Next set the boot pins to UART2 boot mode as shown in this section

The following actions can then be performed, where "COMx" refers to the COM port found in the previous step (i.e. COM8). For C6748 boards, replace "OMAPL138_LCDK" with "C6748_LCDK".

  • Erase the entire NAND (optional):

sfh_OMAP-L138.exe -targettype OMAPL138_LCDK -flashtype NAND -p COMx -erase

  • Flash bootable AIS image (ais_image.bin) to block 1 of the NAND:

sfh_OMAP-L138.exe -targettype OMAPL138_LCDK -flashtype NAND -p COMx -flash_noubl ais_image.bin

Run the commands and then power cycle or reset the board to initiate the process.


Due to recent reports on TI E2E regarding the out of box demonstrations on C6748 LCDK and OMAPL138, we are providing the binaries that are used by the board manufacturer to flash and run demo on the board so that if you run into similar issue, you can either restore the flash with factory images or run diagnostics to confirm functionality
  • CCS Method
  1. Connect to the ARM or DSP with the GEL file loaded, which will auto-initialize the DDR
  2. Open (CCS3) or import (CCS4, CCS5) the NANDWriter_ARM or NANDWriter_DSP project
  3. Modify the #define "NANDWIDTH_8" to "#define NANDWIDTH_16" in nandwriter.c
  4. Rebuild and run the code

SD/MMC Flashing

See the following wiki for details: [6]

Power Sequencing


To keep the cost low, the L138/C6748 LCDK has not followed the right power sequencing recommended by L138/C6748 datasheet. The designer need to implement the right power sequencing for reliable operation. See the following application note for details.

Cool Project Demonstrations!

Finger Printing Demonstration

video platform video management video solutions video player
Finger Printing on C6748 kit

C6748 LCDK comes with pre programmed Flashed demos. Authentec Finger print sensor mounted on the board is capable of sensing finger with 100% accuracy. The finger print demo provides flexibility to create multiple finger selection for different users by swipe sensor technology. The finger prints are matched in fraction of seconds. Enrollment for each user is completed in four steps and it takes fraction of a second to match the finger print on 300 MHz on the C674x floating point DSP. This demo is also 100% percent accurate for results and has an easy connection to the PC for running the demo and viewing the results.

Note: This demo can be recreated only on initial versions of LCDK that were populated with the fingerprint sensor.

Face Detection Demonstartion

Face Detection on C6748 kit

Second pre flashed demonstartion is Face Detection. This demo supports frontal face detection by using an OpenCV based Haar detect object algorithm. The demo can detect multiple faces in a frame and uses a composite camera to capture and VGA to display the image. The demo also supports D1(720x480) resolution image processing and real time video capture and display This requires additional hardware to be connected to the board to take VGA capture through composite  camera interface and output is displayed on the VGA display connected to the VGA port.

Above demonstartions comes with the C6748 BIOS C6 Software development Kit with the source code of the projects.

Note: The demo code is provided as part of the C6BIOS SDK. The DSP compiled version of OpenCV libraries are provided only in object code.

FAQs (in progress)

The target is being held in reset

Would get "target is being held in reset" error while connecting target like below screen shot.

Reset error2.png

If this issue comes from OMAPL138, then we might have tried to connect the DSP core which should be wakeup by ARM core since OMAPL138 is ARM boot master device, that means ARM comes out from sleep first when RBL code executed then application code or user should wake up the DSP.

To resolve this issue, you should connect the ARM core first and respective gel file get initialize all the peripherals and wake up the DSP.

You should give the following gel file for ARM core.

If CCSv6 C:\ti\ccsv6\ccs_base\emulation\boards\lcdkomapl138\gel\OMAP-L138_LCDK.gel

If CCSv5 C:\ti\ccsv5\ccs_base\emulation\boards\lcdkomapl138\gel\OMAP-L138_LCDK.gel
