Hi,<br>
<br>
Few options you can double check<br>
1)Make sure your primary application is calling rte_pdump_init()/ret_pudmp_uninit() to initialize/uninitialize the pdump library.<br>
2)If you are using a shared library build, double check you are linking pcap pmd properly in primary build as explained in below link<br>
<a href="https://www.mail-archive.com/users@dpdk.org/msg05039.html" rel="noreferrer" target="_blank">https://www.mail-archive.com/users@dpdk.org/msg05039.html</a><br>
<a href="https://stackoverflow.com/questions/62795017/dpdk-pdump-failed-to-hotplug-add-device" rel="noreferrer" target="_blank">https://stackoverflow.com/questions/62795017/dpdk-pdump-failed-to-hotplug-add-device</a><br>
3)If you are passing any pci device using eal "-w" option to primary, try to pass the same device to secondary also using "-w" option . <br>
<br>
If you still see the issue please paste the full primary and secondary application run log with command that you are running.<br>
Also what kind of build you are using.<br>
<br>
Thanks,<br>
