Hi Steve!
The default routing table size is at 128 entries, that's too much for
the samr21-xrpo :)
Can you try the following:
BOARD=samr21-xpro make clean all RPL_MAX_ROUTING_ENTRIES=6
and see how this works out for you?
You can even play a little bit around with the entry size, maybe you
will find better values for your use case.
Cheers,
Cenk

Hi RIOTers,
I am trying to compile the latest rpl_udp example for my SAMR21 Xpro.
The compile was fine but I had an error message from the link. It
bailed out with a ram overflow error.
~/RIOT/examples/rpl_udp$ make BOARD=samr21-xpro

The toolchain version is "gcc version 4.9.3 20141119 (release)
[ARM/embedded-4_9-branch revision 218278] (GNU Tools for ARM Embedded
Processors)". The RIOT source code was pulled off github as of today.
Any suggestion? Thanks.
