TCI6486CSL: TMS320TCI6486 DSP EMAC Rx DMA SOF Overrun Problem

Part Number:TCI6486CSL

Hi,

On TMS320TCI6486 DSP, there is problem where after some run DSP EMAC0 Receive Channel DMA Head Descriptor Pointer Register becomes null leading to all packets drop on EMAC by incrementing DMA Rx SOF Overrun counters. I am suspecting it is due to some bug in the EMAC module, which is leading to buffer overflow in the EMAC driver. There is only one EMAC port in use. Any details/hints for the problem will be helpful.

Thanks!
