[yocto] PXE Boot NFS not working

[Raymond Yeung]

I've an Intel Xeon-D board.  I could boot up the board with PXE booting.  However, this seems to be always looking for "removable media"; if there is none, it would hang (in a .sh file).  I want to explore NFS approach.  So far, I've read up, experimented on NFS setup via pxelinux.cfg/default file.  I'm able to manually perform nfs mount from client side, but doing it via configuration file doesn't seem to work.


Now, I'm wondering if my bzImage and initrd files are built correct.  According to this article here:


https://wiki.yoctoproject.org/wiki/Poky_NFS_Root


Two requirements must be met.  First one is that the network driver must be built into the kernel rather than being a module.  Second one is to disable network init script.


Does anyone know how to do the above two items?  What recipe file(s) should I modify?


Thanks,

Raymond
