All you need is the 5 lines I showed below. As long as you define client_ip, the default u-boot env will use NFS. No need for uenvcmd, etc. Robert made NFS booting really simple: http://elinux.org/Beagleboard:U-boot_partitioning_layout_2.0#nfs_support Regards, John > > Thanks again > Giles > > > On Wednesday, 30 July 2014 17:43:50 UTC+1, john3909 wrote: >> >> From: Giles Godart-Brown <ggodar...@gmail.com <javascript:> > >> Reply-To: "beagl...@googlegroups.com <javascript:> " >> <beagl...@googlegroups.com <javascript:> > >> Date: Wednesday, July 30, 2014 at 12:24 AM >> To: "beagl...@googlegroups.com <javascript:> " <beagl...@googlegroups.com >> <javascript:> > >> Subject: Re: [beagleboard] unable to boot Beaglebone Black from NFS >> >>> Thanks for your help, but sadly, on this version a uEnv.txt just containing; >>> console=ttyO0,115200n8 >>> client_ip=192.168.10.47 >>> server_ip=192.168.10.118 >>> gw_ip=192.168.10.1 >>> root_dir=/home/bone/bbb_nfs_root >>> >>> does not work, it doesn't even fire up the ethernet port (no activity >>> lights), I'm guessing because there is no eth0 defined and its perhaps >>> trying to fire up the USB network or something. >> Make sure you are using the latest version of u-boot.
