6.3.10. OMAP-L138/C6748 LCDK Hardware Setup¶

6.3.10.1.1. Hardware¶

Information on the LCDK hardware, including DIP switches, LEDs, and user bottons, can be found in the LCDK User’s Guide at the following link.

OMAP-L138/C6748 Low-Cost Development Kit User’s Guide

6.3.10.1.2. Powering the LCDK¶

The board can be powered with 5V input through the J1 barrel connector.

6.3.10.1.3. UART Connection¶

Connect a mini-USB cable between UART port (J3) of the EVM and the host PC. Open a serial console (e.g. Tera Term) on the host PC and configure the serial port as follows.

• Baud rate - 115200
• Data length - 8 bit
• Parity - None
• Stop bits - 1
• Flow control - None

6.3.10.3.1. Hardware Setup¶

• Set the SW1 DIP switches to UART boot mode as shown in the `DIP Switches`_ section.
• Connect an external emulator to the J6 header.
• Power on the LCDK using the J1 barrel connector.

6.3.10.3.2. Software Setup¶

• Code Composer Studio IDE - Download

• Processor SDK RTOS for OMAP-L138/C6748 - Download

• Setup the software environment as described in the “Download and install software” section of the Processor SDK RTOS Getting Started Guide

• Build an example. Below are some suggested examples to get started with.

  • No OS (Bare Metal) Example
  • TI-RTOS Kernel Example
  • GPIO LED Blink Example

6.3.10.3.3. Creating a Target Configuration File¶

• In CCS, navigate to View -> Target Configurations.
• In the Target Configurations window, right-click and select “New Target Configuration.”
• For Connection, select your external emulator.
• For Board or Device, select LCDKC6748 or LCDKOMAPL138 as shown in the following image, and click Save.

• Navigate to the Advanced tab and ensure the GEL file is loaded for the ARM9_0 core (OMAP-L138) or C674X_0 core (C6748).

6.3.10.3.4. Connecting to Target and Loading/Running Program¶

Connecting to Target

• In CCS, navigate to the Target Configurations window.
• Right-click on the newly created target configuration and select “Launch Selected Configuration.”
• Right-click on the ARM9_0 core for OMAP-L138 or C674X_0 core for C6748, and click “Connect Target.”

The following GEL outputs should appear in the CCS Console view.
