Starterware DDR test enhancement

OMAP-L138

CCS 6.1.1

Starterware 1.10.04.01

All:

In our board testing, we are using the ARM to test DDR memory prior to loading DSP code into it from NAND flash memory.

There is an enhancement request to be able to "immediately stop" the DDR test if an "ESC" key has been depressed.

I was able to make changes to the UartEcho.c to detect an "ESC" and print an "E" to the UART when it was detected.

However, when I tried to make changes to the DDR memory code, as soon as I enabled the UART interrupt, the normal

flow of the test output stopped, and about the only thing I was able to see was the "echo" of characters.

Present DDR test did not use UART interrupts.

The UartEcho code works with 3 interrupt flags: 

UART_INT_LINE_STAT 
UART_INT_TX_EMPTY 
UART_INT_RXDATA_CTI

If I am trying to monitor only RX, do I need to set up the first two flags?

Thanks for any help!
