Hello List,
I apologize in advance for the long email and my obvious lack of experience
at this.
I've been working on trying to get a couple of dev boards (very similar to
SAM9G20) and AT86rf231 radios working.
I have followed the instructions found in [1] and [2] and have gotten the
boards to boot the latest kernel . However I cannot get RF data out to the
air. I have confirmed this by using a sniffer.
I am fairly confident that the board is talking to the radio as I see the
following debug messages:
[ 1.197000] at86rf230 spi1.0: Detected at86rf231 chip version 2
[ 1.203000] at86rf230 spi1.0: Melvin Was here
[ 1.207000] at86rf230 spi1.0: Status: 08
When listing the physical devices I get the following response:
electrum100:~# iz listphy
wpan-phy0 IEEE 802.15.4 PHY object
page: 0 channel: n/a
channels on page 0: 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26
following with the directions when I try to initiate the coordinator
(izcoordinator -i wpan0 -s 1 -p ABCD -c 26 -l lease -d 2) I get the message:
"izcoordinator[825]: genl_ctrl_resolve: Out of memory", but looking at the
source code it doesn't not appear to be an issue. Could anyone confirm this?
The next few steps appear to succeed without any issues. The interfaces look
are as follows:
lowpan0 Link encap:UNSPEC HWaddr
BA-BE-CA-FE-CA-FE-00-00-00-00-00-00-00-00-00-00

However when I try to ping no data is seen by the sniffer and I get the
following response:
electrum100:~# ping6 -Ilowpan0 fe80::11:22ff:fe33:4438
PING fe80::11:22ff:fe33:4438(fe80::11:22ff:fe33:4438) from

>From fe80::babe:cafe:cafe:0 icmp_seq=1 Destination unreachable: Address

Is there anything I am doing wrong here?
Mainline Kernel was updated to remove NLA_PUT*() macros as of commit sha:
b3fe91c53a0a2e1a665b451bd306bcb5e56c2e97. Looking at iz tools NLA_PUT*
macros are widely used, is this going cause a problem with iz tools?
Thanks in advance
