Hi, can you please give a few more details about your setup? What version of the Intel DPDK are you using? I tried using the command you give below on my system with 82599-based NICs and testpmd starts up without any issues.
Here's the (clipped for brevity) output that I get: $ sudo ./testpmd -c 0x0f -n 2 -m 512 -- -i --portmask=0x3 --nb-cores=2 --pkt-filter-mode=perfect --rxq=2 --txq=2 EAL: No free hugepages reported in hugepages-2048kB EAL: Detected lcore 0 as core 0 on socket 0 EAL: Detected lcore 1 as core 1 on socket 0 ... <snip>... Interactive-mode selected previous number of forwarding ports 4 - changed to number of configured ports 2 Configuring Port 0 (socket 1) Configuring Port 1 (socket 1) Configuring Port 2 (socket 1) Configuring Port 3 (socket 1) Checking link statuses... Port 0 Link Up - speed 10000 Mbps - full-duplex Port 1 Link Up - speed 10000 Mbps - full-duplex Port 2 Link Up - speed 10000 Mbps - full-duplex Port 3 Link Up - speed 10000 Mbps - full-duplex Done testpmd> Perhaps you could also try turning on some of the IXGBE debug options in your compile time config e.g. defconfig_x86_64-default-linuxapp-gcc. Setting "CONFIG_RTE_LIBRTE_IXGBE_DEBUG_INIT" and "CONFIG_RTE_LIBRTE_IXGBE_DEBUG_DRIVER" to "y" might provide some useful output.
