Hi,

Query No : 1

I am working with EVMC6670 board. I want to receive a Ethernet packet from a PC to the core 0 of the DSP. My query is that, whenever an Ethernet packet is to be received by the DSP core, is it compulsory that the packet has to take path

                   SGMII -> Gigabit Ethernet Switch -> Packet Accelerator -> Packet Streaming Switch -> PKTDMA -> QMSS -> Cpre 0. ..... ?

I dont want to use Packet Accelerator module. Is it possible to receive a Ethernet packet from a external PC without using Packet Accelerator and Security Accelerator modules .....? Is the below path possible.....?

                   SGMII -> Gigabit Ethernet Switch -> Packet Streaming Switch -> PKTDMA -> QMSS -> Cpre 0. ..... ?

My requirement is to send and receive Ethernet packets from core 0 to external PC..

Query No : 2

The example code shared by TI uses Packet Accelerator to send and receive Ethernet packets. Is there any example projects on usage of EMAC module, to send and receive Ethernet packets without using Packet Accelerator and Security Accelerator, shared by TI ....? Also is there any reference document for EMAC module for C6670 shared by TI ....?

Thanks and Regards,
