Hello,
I'm setting up an NFS server for a ROACH-1 board. I've done this a couple
of times before but this time there's an issue I've never encountered. The
ROACH board is assigned the correct ip address (dhcp is working) and seems
to load the uImage just fine. However, when it attempts to mount the root
directory it suddenly fails and the kernel panics (see attached minicom
output). My issue is very similar to this post from 2015
<https://casper.berkeley.narkive.com/5CLtX8BR/roach1-not-working> except
I'm not getting a useful NFS error. I don't have another machine on this
subnet that I can use to test the NFS mounting from, but I am able to mount
that directory using 'sudo mount 192.168.4.12:/srv/roach_boot_etch /mnt'
from the same host (I'm not sure if this undermines NFS and just remounts
the target).
Has anyone else seen something like this before? My ethernet connect is
100Mbps, my exports match what's in the dnsmasq configuration file, I've
made sure to restart all services (nfs-kernel-server, dnsmasq, etc.) after
all changes, and permissions for the boot/etch directories not restricted
(currently all is 777, but there is no change when using 755). In fact, as
far as I can tell, my current configuration is identical to others that I
have working. I've included the contents of my dnsmasq config, dnsmasq log,
the output of rpcinfo -p, exportfs -rva, and showmount -e to this message
as well. Any suggests for what to try next at this point would be greatly
appreciated!
Best,
LD
