How to use DPDK& Ethercat IGH master station

[ruziniu]

The description at the URL 【https://eci.intel.com/docs/3.2/components/ethercat.html#install-igh-ethercat-master-stack】 is not very detailed. Is there a more detailed tutorial that can help me use DPDK to run the IGH master in user space?

Hi ruziniu,

Please take a look at this page, I believe this is what you are looking for.

Thank you for your reply. I followed the instructions on the website you provided. However, I encountered a new issue and hope you can help me resolve it:I used the source code to install dpdk, version: dpdk-stable-24.11.3.

When executing the following steps:

cd ighethercat

./bootstrap

./configure --enable-sii-assign --disable-eoe --enable-hrtimer --disable-cycles --enable-usermode --enable-daemon --enable-dpdk

make

I got the following error message while running make.
