</summary>
|
||
|
||
#### Step 1: Configure the Boot Switches
|
||
|
||
Set the DIP switches as follows:
|
||
|
||
- Switch 1: **ON**
|
||
- Switch 2: **OFF**
|
||
- Switch 3: **OFF**
|
||
|
||
Then connect the board to the PC using the USB port.

|
||
|
||
Select the compiled firmware file, then click the **Program** button to start flashing.
|
||
|
||
#### Step 3: Restore the Boot Switches
|
||
|
||
After programming is complete:
|
||
|
||
1. Disconnect the USB cable.
|
||
2. Set all DIP switches to the **ON** position:
|
||
- Switch 1: **ON**
|
||
- Switch 2: **ON**
|
||
- Switch 3: **ON**

<b>Flashing Firmware with CCS and JTAG</b>
|
||
</summary>
|
||
|
||
#### Step 1: Open the CCS Workspace
|
||
|
||
Launch **Code Composer Studio (CCS)** and open the workspace that contains your project.
|
||
|
||
#### Step 2: Import the CCS Project
|
||
|
||
From the CCS menu, select:
|
||
|
||
**Project -> Import CCS Projects**
|
||
|
||
as shown in the image below.

|
||
|
||
Follow the prompts to select and import the desired CCS project.
|
||
|
||
#### Step 3: Build and Debug the Project
|
||
|
||
Build the project to generate the executable file.
|
||
|
||
Then connect the JTAG debugger to the target board and start a debug session to download and run the firmware.
