Hi everyone,
what do I need to do to get the IEEE802.15.4 and 6LoWPAN stack working on
my computer? I built the net-next kernel [1] with all the drivers compiled
as modules and the linux-zigbee userspace tools [2].
Everything compiles without errors.
Then I more or less follow the Getting started guide in your wiki [3], I
use the fakelb driver for testing. Everything seems to work fine, I bring
up my wpan0 interface and see a "ieee802154fakelb: added ieee802154
hardware" in the kernel log.
Then I try an 'iz assoc', which is killed immediately and I get a kernel
oops in the kernel logfile (see below for logfile).
Can anyone help get this working?
Thanks.
