Hi,

I'm new to DPDK.

I have gone through the user guide, set up environment, hugepages. I can
get the helloworld app work. Now, when I tried to play with the testpmd
app, I got the following issue:

[root@localhost dpdk-1.8.0]# build/app/testpmd -c 0x2 -n1 -- -i
--nb-cores=1 --nb-ports=0x1

.....

EAL: TSC frequency is ~2594110 KHz

4: [/lib64/libc.so.6(__libc_start_main+0xf5) [0x7f06df8e2af5]]

.....

It says the core mask is not right. I set it to 0x2 because my CPU
only has 2 cores. I don't quite get it.

Can someone help me with this? And has anyone else encountered the same issue?

Thanks!
