ARM Communications via UART Down

$

Hi,

I am currently working on an OMAPL138. During the development of the DSP executable, communications via a UART channel to TeraTerm was used for debugging purposes. The communication's code was based on TI's example code and worked fine.

I am now in the process of coding the ARM. The ARM is printing lines to terminal running Minicom using the printf statement. This works fine until the DSP executable is loaded and starts to run. The DSP is still able to communicate (now to TeraTerm) with the same code, but all communications to and from the ARM is lost.    

Even if I remove all UART_TxString commands from the DSP code and remove the initialization of the UART port from the DSP code, communications from the ARM is still lost when the DSP executable starts.

Can anyone please tell me why this is and how to avoid it?
