Hi,

The dpdk-pdump tool cannot be run as a standalone. The ``dpdk-pdump`` tool can only be used in conjunction with a primary
application which has the packet capture framework initialized already. This point is added in latest doc $dpdk/doc/guides/tools/pdump.rst.

In DPDK test-pmd is already modified to initialize packet capture framework. 
So, you must run test-pmd first to do Rx/Tx of the packets and also to initialize Packet capture framework.
Once test-pmd started , in another window run dpdk-pdump tool, then you will be able to see the packets in pcap file.

If any questions do let me know.

Thanks,
Reshma
