<p class="MsoNormal">Hi, <br>
<br>
i am running DPDK 22.03 on a NXP platform, using 2 eth ports (dpmac, dpni, dprc config should be OK, as i get bursts of packets with testpmd and in a little customized app<br>
which is just checking if packets are bursted in mempool.<br>
<br>
So then i tried to use pdump and pcapng to write out a capture.pcapng file.<br>
<br>
I created mempool and ringbuffer according tot o the dumpcap-example, (rte_eth_dev_configure, rte_eth_dev_adjust_nb_rx_tx_desc, rte_eth_rx/tx_queue_setup, rte_eth_dev_start with the portid i have and which was veryfied by my little customized app as working
properly) <br>
but when i call enable_pdump i am running into a segmentation fault.<br>
<br>
Validation of port, ring, mp, flags are ok.<br>
the problem seems to come from snprintf. There is no different behaviour no matter if i use enable_pdump or enable_pdump_by_deviceID or enable_pdump_bpf.<br>
PDUMP seems to have trouble whith my portID or deviceID.<br>
<br>
<o:p></o:p></p>
<p class="MsoNormal">Can you give any hint, what might go wrong here? Or what i could try to get this stuff running?<o:p></o:p></p>
<p class="MsoNormal">Thanks in advance.<o:p></o:p></p>
