T4P4S switch running exited with error code 255 (Switch execution error)

[chenxiang2019]

Hi all.

I'm new to t4p4s. After I installed related dependencies and t4p4s, I tried to run a simple port-forwarding program using t4p4s via the following steps.

1.Bind two ethernet ports to DPDK drivers (version 17.11, Ubuntu 16.04).

2.Add one line to examples.cfg:

switch                              @nonic

3.Run t4p4s with my program switch.p4 (written in P4 16 with V1Model):

./t4p4s.sh MY_PATH_TO_P4/switch.p4

After that, I received the following messages:

 - Runtime options were: --log-level 3 -c 0x3 -n 4 -- --config "" 

How can I resolve this problem? Any suggestions will be appreciated.
