RTOS/TMS320C6678: packet accelerator paSimpleExample receiving external packets

Part Number:TMS320C6678

Tool/software: TI-RTOS

hi all,

i am working on trying to use packet accelerator to route packets from external device into each of the dsp cores on a C6678 chip. i am starting with the paSimpleExample provided by pdk_C6678_1_1_2_6.

The packet sent by "sendPacket ()" in paExample.c was received correctly , but  when i try to send packets from an external computer into the DSP, the DSP doesn't seem to receive the packets. 

what do i need to modify in this example so that the dsp can receive packets from external device using PA? 

Thanks. 

my development environment setup,

i have the DSP card plugged into an AMC chassis connected to a common switch with a linux server.

on the linux server, I did "arp -s  172.31.16.87 c4:ed:ba:98:18:93" . i also modified the "config.h" to use the actual mac address of the chip instead of the fake one. 

i'm using code composer studio v7 with MCSDK 1.1.2.6 and sysbios 6.46.5.55.
