It should suffice to create a file "cc110x_params.h" with the correct
SPI/pin parameters and put it in your include path, then add "USEMODULE
+= cc110x gnrc_netdev2 gnrc_cc110x" to your makefile, in addition to the
other gnrc modules. I use gnrc_networking as a base and just add those
modules.
Check "boards/msba2/include/cc110x_params.h" for an example parameters
file, but make sure to adjust the settings.
Last time I tried there was a problem with 6lowpan IP header
compression, so if you can't communicate between nodes using IPv6, try
disabling iphc (by adding "DISABLE_MODULE += gnrc_sixlowpan_iphc" to the
application's Makefile).
Have fun!

On native platform (linux) I had no problems running RPL using this
tutorial:
https://github.com/RIOT-OS/RIOT/wiki/Tutorial%3A-RIOT-and-Multi-Hop-Routing-with-RPL
I tried in many ways above configuration with CC1101. After reboot one
frame is sent. After initializing RPL another one. When "rpl root 1
2001:db8::1" command is executed no more frames are transmitted.
A new RPL DODAG was successfully added. "rpl" command gives reply with
instance table and dodag table marked.
I turned on DEBUG in gnrc_rpl_dodag.c, so on native I've got many
messages like these:
> Instance with id 1 exists
> DODAG with id: 2001:db8::1 does exist
> trickle callback: Instance (1) | DODAG: (2001:db8::1)
On my own platform with CC1101 no messages appears.
I also tried with "DISABLE_MODULE += gnrc_sixlowpan_iphc" and it was the
same. I noticed that despite disabling IPHC phrase
-DMODULE_GNRC_SIXLOWPAN_IPHC is present in CFLAGS list (make info-build).
Transceivers are OK. After one module sends message, another one is
receiving it. So SPI and CC1101 is probably working correctly.
I have no ideas how to overcome these problems. Could you give me some
clues?
