21469 Link Port RX Stalls

I have two ADSP-21469 SHARCs exchanging a small amount of data almost constantly (@ approximately 3KHz).  The master DSP is also receives data over the UART.  Something about the LINK PORT and the UART receiving data at the same time is causing the LINK PORT receive to fail.  I am masking the UART interrupt during the LINK PORT transfer in an attempt to prevent the UART interrupt from executing at the same time.

 

NOTE: I have tried both a CORE transfer and a DMA transfer with the same results.

 

Anyone seen this before.

 

Thanks,

Joe
