Hello. I'm working on getting the BBB booting over network, for our CI
testbench. I've got it booting the kernel over tftp:
setenv autoload no
setenv bootdelay 2
setenv ipaddr 192.168.0.2
setenv gatewayip 192.168.0.1
setenv netmask 255.255.255.0
setenv serverip 162.x.x.x
tftp 0x80300000 /boot/one/vmlinuz-3.8.13-bone70
tftp 0x81600000 /boot/one/initrd.img-3.8.13-bone70
setenv initrd_size ${filesize}
tftp 0x815f0000 /boot/one/am335x-boneblack.dtb
setenv bootargs 'console=ttyO0,115200n8 root=/dev/nfs
nfsroot=162.x.x.x:/root/one
ip=192.168.0.2:162.x.x.x:192.168.0.1:255.255.255.0:one:eth0:off quiet
init=/lib/systemd/systemd'
bootz 0x80300000 0x81600000:${initrd_size} 0x815f0000
but connecting to the NFS root filesystem times out:

It's timing out, but under DHCP it doesn't even get that far. It doesn't
list the "rootpath" so I wonder if that got passed to the kernel?
Here is the exports file on the server:
/tftpboot/root/one 162.x.x.x/28(rw,nohide,insecure,no_subtree_check,async,
no_root_squash)
I can mount the nfs share on another device:
root@beaglebone:/# mount 162.x.x.x:/ /mnt
root@beaglebone:/# cd /mnt/
root@beaglebone:/mnt# ls
tftpboot
I'm not sure what to try next. Any ideas?
