RTOS/TMS320C6678: NDK emac client example: how to receive raw packet (Nimu_testRecvRawEth)

Sergey Shabunin

Part Number: TMS320C6678

Tool/software: TI-RTOS

Hello, I'm trying NIMU_emacClientExample from "c:\ti\pdk_c667x_2_0_7\packages\ti\transport\ndk\nimu\example\client\c6678\c66\bios\". Function NIMU_testNetworkIpAddr() creates two tasks: Nimu_testSendRawEth and Nimu_testRecvRawEth. First task sends a raw packet and I see it in wireshark, second task must receive raw packet. What should I do to make it work? What kind of packet is it waiting?

Hi,

Form the code, sraw = socket(AF_RAWETH, SOCK_RAWETH, 0x300);

So you need to send Ethernet Type 0x300 packets from PC to C6678.

Hello, thank you for the answer. I've tried to send packets with 0x0300 type. But DSP didn't receive them. And in Wireshark they were detected as type "LLC". So I changed the type to 0xffff (I tried some other like 0x0888 or 0x0801 and they worked too). And changed the code, sraw = socket(AF_RAWETH, SOCK_RAWETH, 0xffff). And catched the packets.
