Hi Ali, Thanks for your reply In an unmodified copy of gem5, I made the data in packet.hh as public and tried to print it in schedSendTiming. It shows 0 as value for all the packets when I print it using (int)*(pkt->data). Is the data that is fetched from cache being sent to cpu? If yes how do I track(print) it? Thank you once again for your time.
