Raspberry PI and netrom

Raspberry PI and netrom

[kd1zd]

I have a Raspberry PI running the latest version of wheezy downloaded 
from the Raspberry site.

I'm getting the following error trying to configure NET/ROM:

sudo nrattach netrom
nrattach: cannot find free NET/ROM device


I have a working AX.25 setup.  I have loaded the netrom kernel module 
and verified with lsmod.

My nrports:

# name callsign alias paclen description
#
netrom   KD1ZD-6  ENFCT  235  Netrom Switch

My nrbroadcast:

# ax25_name min_obs def_qual worst_qual verbose
#
vhf     5       192     100     1



Any ideas about what might be going wrong?  I notice after running the 
nrattach command, that nr0-nr3 appear in ifconfig, even after running 
the command only once.

At this point, does dmesg have any exciting news?

Hi,

I am running two RaspBerry Pis with AX.25, NetRom and Rose network devices.
When loading ax25 modules there is no problem.
However, due to modules or kernel bugs, when loading NetRom or Rose modules
with modprobe or if netrom or rose are listed in /etc/modules, then ALL netrom
and rose devices are wrongly initialized.

This can be easily bypassed by editing ifplugd configuration file.

I suggest you edit /etc/default/ifplugd   and replace

HOTPLUG_INTERFACES="all"

by

HOTPLUG_INTERFACES="eth0"

I think I found this the other day, thanks for posting it on the list.

I was able to get my netrom working.

Thank you.
