Hi all,
Just got down to trying this again.
Thanks to Joao for spotting this patch issue - I recompiled to get our spi
pin back! :)
Following the instructions, I run the echo command to load the DT for the
MRF24J40. Had to enable the root account in Ubuntu, since simply doing
"sudo echo ..." was not enough permission-wise.
It seems to work fine, as dmesg shows:

I then go on to run the setup script, but it seems the "iz add" command
fails to link the physical device to an interface.
This is the script output:
root@arm:/home/ubuntu# ./setup
++ set -e
++ ifconfig lowpan0 down
lowpan0: ERROR while getting interface flags: No such device
++ /bin/true
++ rmmod mrf24j40
++ modprobe mrf24j40
+++ iz listphy
+++ grep wpan-phy
+++ tail -n 1
+++ awk '{print $1, " " }'
++ DEV='wpan-phy1 '
++ iz add wpan-phy1
Receive failed: Netlink Error (errno = Invalid argument)
When manually reproducing the script, I can see the MRF (I think..):
root@arm:/home/ubuntu# iz listphy
wpan-phy1 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
But iz add fails:
root@arm:/home/ubuntu# iz add wpan-phy1
Receive failed: Netlink Error (errno = Invalid argument)
Using -d to get a more detailed report, I get:
root@arm:/home/ubuntu# iz add wpan-phy0
Receive failed: Netlink Error (errno = No such device)
root@arm:/home/ubuntu# iz add wpan-phy1
Receive failed: Netlink Error (errno = Invalid argument)
root@arm:/home/ubuntu# iz -d add wpan-phy0

Any ideas would be welcome!
