OMAPL138 LCDKC6748 Starterware UART example issue

Hello,

I am using OMAPL138 LCDK, with CCSv6.1.1. I have installed BIOS C6SDK 2.0. As per the getting started guide, I managed to check the Linux kernel boot from SD/MMC Card. My issues start as follows:

1. Boot mode switch is set to: 2-ON, 3-ON, 4-ON, all others are OFF

1. I tried to create a DSP based hello world application using CCS and tested it.

2. I wanted to test the RASTER example from Starterware, the project builds fine but does not show any output on the VGA  Display. I also tried other examples from Starterware UART, and  few related to USB, but could not verify the output.

3. From the rt-dsp.com  website, I came to know about reflashing the OMAPL138 LCDK with WINDSK8 for proper operation of the LCDK. So, i did that and retried the RASTER, FACEDETECTION AND VIDEO LOOPBACK  examples, everything worked without any issues.[ Boot mode switch is set to: 2-ON, 3-ON, 4-ON, 8-ON].

4. Now, I wanted to test UART-USB communication, so I imported the UART_ECHO example from starterware and tried executing it. I use hyperterminal to check the communication, and i get the following

Since, its an Echo example, I press the buttons on the keyboard, however I cannot see any characaters printed on the Terminal window. I tried to debug the code and found that the execution never enetrs the ISR, but waits infinitely at the while(1) loop. One thing to note is that RTC example from Starterware also uses UART to communicate with the Terminal to update the Time, this works fine, but examples such as HOST_MSC, USB_dev_Serial which utilises the UART module does not receive any data fro the terminal.

Any suggestions will matter a lot to me.
