Creating Network Interface (or get right BSP) - Yocto Project


I've used Yocto Generic x86_64 to boot up my board with Intel Xeon D 1500 family processor. On Yocto's website, I don't see any BSP for this processor (or any eval platform).

After boot up, I couldn't find any network interface (other than lo and sit for 6to4). I don't need the 6to4 (or sit) interface, but instead need an external network interface for common IP functions. How do I do that?

In the past, I'd dealt with other OSs, e.g. QNX. It came as part of a BSP. Network interfaces were created/defined within BSP. So in this particular case (or in other distribution), how would one proceed? I suspect the kernel I'm using misses other devices also.

If there're any good training courses that could help, please also let me know.

Never heard of BSP for Linux, but I'm not familiar with embedded, so maybe there is. Anyhow, you can get kernel sources, configure it for your board and build and install your own kernel.

Issue Resolved

Firstly, I found out that there's actually a BSP (well, close enough) for my board. Intel Xeon-D used to have a codename "Broadwell DE", and it has a reference board codenamed "Camelback Mountain". There's in fact a BSP from Yocto Project for that. I picked up a rebuild there and was able to resolve this network interface issue. The trick here is to use the full build (i.e. -sato, though not sure whether this is an acronym for something), instead of the -minimal build. The latter would give you a "sit0" interface and a "lo" interface, without any of the eth0/eth1 etc. interfaces that you need.
