Re: [dpdk-users] issues with dpdk-pdump

Hi Rami,
Thanks for replying to my message.

I followed the procedure like you said and here is what I get when I run the dpdk-pdump after running the testpmd.

I actually past the crash (because of rte_memconfig) that I reported earlier.  It seems to be because of the --no-shconf that we are passing for rte_eal_init. Once I removed it I got past the error but now I get the following error

These are the arguments now that we pass to rte_eal_init ' -c ff -n 4 -r 1 -m 800'. 

And, here is how I start the dpdk-pdump
./dpdk-pdump --  --pdump 'port=0, queue=*, rx-dev=/tmp/rx.pcap, tx-dev=/tmp/tx.pcap'


And I am running with DPDK 18.05. 

Any help is greatly appreciated.

Thanks.

Hi Srinivas,
Can you do a simple test to make sure your setup is ok ?
The suggested test is: instead od running you app, simply do the following:
First, bind a port to DPDK.
Then, run testpmd app (build/app/testpmd; as testpmd calls
rte_pdump_init() if RTE_LIBRTE_PDUMP is defined).
Then run again the dpdk-pdump, and post the result.
For me this works with dpdk-18.08, I am aware that you are using an older version, but it should work also for you I believe.
Please note that I had to remove the while spaces in the command, but anyhow these whitespaces did not cause the error about rte_eal_config_attach() you had, but a parsing error; after I removed these whitespaces, everything was fine, no errors; what I actually ran is; ./build/app/dpdk-pdump --  --pdump 'port=0,queue=*,rx-dev=/work/rc.pcapng,tx-dev=/work/tc.pcapng'

and the log shows:
