Hi,
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
which is just checking if packets are bursted in mempool.
So then i tried to use pdump and pcapng to write out a capture.pcapng file.
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)
but when i call enable_pdump i am running into a segmentation fault.
Validation of port, ring, mp, flags are ok.
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.
PDUMP seems to have trouble whith my portID or deviceID.
Can you give any hint, what might go wrong here? Or what i could try to get this stuff running?
Thanks in advance.
