Hi all, Im working on trimode Ethernet Mac core on Virtex 4. There is a tool in thie core called ":Xilinx Hardware Demonstration Platform" which acually displays the peckects being send and you can also set some parameter for the packet like destination address, length etc. Now the problem is with the destination address. Im entering a destination MAC address in its parameters but in the "frames read from FIFO" the value of the DA doesnt change. it reamins FF:FF:FF:FF:FF:FF; . So plz help me in this regard as how to change DA. plz reply ASAP.
