<p class="MsoNormal"><span lang="EN-GB">I’m recently compiled my rtems for a Xilinx board bsp included in RTEMS. In a future I will add TCP/UDP connections to my application so I just want to assure I did the correct installation. At RTEMS compilation I included
the –enable-networking option. I have worked with RTEMS using the rtems-libbsd implementation with –disable-networking option. So I’ve got the following questions, why the use of rtems networking in some cases and libbsd in others? Does arm need rtems-libbsd
or it can work with the RTEMS networking implementation?</span></p></div></div></blockquote></div></div><div dir="auto"><br></div><div dir="auto"><div dir="auto" style="font-family:sans-serif;font-size:12.8px">The network stack in the RTEMS source tree is old (now called legacy) and IPV4 only.
