I build image from [lx2160a\_build](https://github.com/SolidRun/lx2160a_build) with DPDK，and deploy to LX2160A. But when I run this command, ```auto dpdk-devbind.py -s ``` give me some error meeags,like those, ```auto lspci: Unable to load libkmod resources: error -12 lspci: Unable to load libkmod resources: error -12 lspci: Unable to load libkmod resources: error -12 lspci: Unable to load libkmod resources: error -12 lspci: Unable to load libkmod resources: error -12 lspci: Unable to load libkmod resources: error -12 lspci: Unable to load libkmod resources: error -12 lspci: Unable to load libkmod resources: error -12 No 'Network' devices detected ============================= No 'Baseband' devices detected ============================== No 'Crypto' devices detected ============================ No 'Eventdev' devices detected ============================== No 'Mempool' devices detected ============================= No 'Compress' devices detected ============================== No 'Misc (rawdev)' devices detected =================================== No 'Regex' devices detected =========================== ``` how to fix it? ---

And you are following the instructions in NXP’s documentation? [NXP](https://docs.nxp.com/bundle/GUID-E5527A77-2F97-4244-BF9C-D08F068EFD16/page/GUID-B305DA25-E082-4C6A-B8F2-50C903505A27.html) ---

Yes,it’s completely step by step. And there is no any Network devices detected. ---

I try to install dpdk from HomePage of DPDK,there is no this problom. But I don’t think it can work with LX2160A, because no DPAA2 driver in that DPDK. ---

I am pretty sure dpaa2 support has been merged into mainline DPDK, or at least partially. I will need to double check that. ---

I expect a DPRC needs to be created with dynamic\_dpl.sh ---

Yes ,I run ```auto dynamic_dpl.sh dpmac.10 export DPRC=dprc.2 ``` and then run dpdk\_testpmd ,it is work. I’m wondering why there are no any network devices displayed and how to fix “Unable to load libkmod resources: error -12”. ---

ok , I will install mainline DPDK,and test it again. ---

You don’t use dpdk-devbind.py on DPAA2. You need to control driver binding using the datapath device trees (DPL / DPC) and/or the NXP run-time scripts - dynamic\_dpl.sh, ls-listmac, ls-addni, etc. If by “no any network devices displayed” you mean in Linux (e.g. ifconfig / ip link) then you need to bind native interfaces to the dpmacs using ls-addni. ---

that is to say,dpdk-devbind.py has no use in DPAA2.
