A bit too fast Seems like I missed this one
(http://www.mail-archive.com/linux-zigbee-devel@lists.sourceforge.net/msg004
46.html) with respect to updating the iz-tool J - I will try this tomorrow
This being said When I have this I would still like to get any kind of
guidance on whats next step in order to test something with 6lowpan?
Can I just do a #ping6 ipv6.google.com and expect this one to start
sending out ipv6 ping packages on the link, or should I do anything
else/special?
Best regards and thanks again in advance

Linux
Hi Pierre-emmanuel, Jon, Dimitri, all,
I'm currently in the middle of porting support for cc2520 to this project
with the final goal of being able to run 6lowpan IPv6 over a cc2520 802.15.4
wireless link. I'm able to follow the instructions given in various email
and on the linux-zigbee wiki, and compile the kernel after applying the
6lowpan patch shared by Jon on email send to the list on the 25/10-2010.
Secondly I have ported the cc2420 driver to support the cc2520 chip with a
cc2591 RF frontend (and I can communicate with the chip over SPI), but after
this the progress pretty much ends - Unfortunately :-( :-)
Now to the questions:
1) Below it's mentioned that you should do:
# iz 6lowpan wpan-phyY
in order to attached the wpan-phyY to a 6lowpan network I assume? Trying to
do this "iz" complains about now knowing the 6lowpan option. I can however
do "iz add wpan-phyY" with no problem, but I assume this won't link it
properly to the 6lowpan networking? What am I missing here?
2) I'm not sure I fully understand this part:
* Create a serial Node with an 802.15.4 interface conform to Dimitri
specification (Cf Linux-zigbee Wiki),
and use an other node with Contiki IPV6 capabilities. Not necessary
during these first tests except for RS/RA behaviour.
I hope that somebodye can help me forward with this and as well let me know
what I might need to do to i.e. make the network stream out a lot of TX
packets for me to check if my TX settings are correct - Next step will then
be RX I think(?). I have a RF sniffer (based on CC2531) with which I assume
I can capture the send packets(?), but since I'm not being able to bind the
cc2520 correctly to the IPv6 networking it seems like I can't make any
packages being send by use of ping6(?). BTW: Is this the right way for doing
initial TX tests, or is there another easier/better way? Do I need any other
special options compiled into the kernel for this to work?
Best regards and thanks in advance - Any kind of feedback or help will be
highly appreciated
Søren

Hi Jon, Dimitri, all,
And many thanks.
I tried all this yesterday.
Great ! it works. I can see 6LowPan frames sended.
Basic steps to get this working for whom who begin with all this (a bit
like me) :
=====================================================================
* Create a serial Node with an 802.15.4 interface conform to Dimitri
specification (Cf Linux-zigbee Wiki),
and use an other node with Contiki IPV6 capabilities. Not necessary
during these first tests except for RS/RA behaviour.
* Get the git devel branch of linux-zigbee, (Starting from a debian dist
at least 2.6.32)
* Apply your (Jon smirl) patches (Kernel and lowpan), (use git-apply
with your patch)
* Compile the linux-zigbee kernel and lowpan tools
* Connect your serial node ad use these commands to test :
# izattach /dev/ttyUSBX
Find the new wpan-phy with # iz list-phy
# iz 6lowpan wpan-phyY
# ifconfig wpan0 up
(Use a sniffer Cf 15dot4 project from Colin O'Flyn to see frames on the
real media with wireshark more recent
than 1.3.3 the best would be 1.5.0 not my case today ...)
My current questions:
===================
- My interface Hardware address is not setted correctly ... it seems
that just 4 or 5 first bytes are setted ?
(even so i see the correct address in the return "zb0x8d..." message
with #dmesg )
- As discussed in previous posts in linux-zigbee mailing list,
I had to have my channel setted (done as a hack of
mac802154_wpan_xmit() from net/mac802.15.4/wpan.c) to see my packets sended.
- Without defining a global address this ping line
# ping6 fe80::ff:ff00:1 -I wpan0 -c1
gives a MAC header containing my own MAC address as source AND dest ?
(seen on the sniffer)
- With a Global IPV6 address defined on the interface
# ip -6 addr add aaaa::1/64 dev wpan0
# ping6 aaaa::ff:ff00:1 -I wpan0 -c1
as got very strange LL addressing and lowpan compression with 16 bit
source address ?
For whom who are interested i join the PCAP files for initial RS/RA
exchanges, and an example of Ping send with Local then global with a
Contiki IPV6 device.
