Hi,
I would suggest to use the functions directly instead of "sailing" around them
with shell commands.
You will need the following:
// the :: destination address [1]. (Alternatively it can be set anywhere using
[2] or [3])
ipv6_addr_t dest = IPV6_ADDR_UNSPECIFIED;
// your next-hop
ipv6_addr_t next = IPV6_ADDR_UNSPECIFIED;
// for example you can use [3] to get the ipv6 address from a string (or set
the values manually)
ipv6_addr_from_str(&next, "fe80::1ac0:ffee:1ac0:ffee");
// get your interface pid of your transceiver handling the address [4]
kernel_pid_t iface = gnrc_ipv6_netif_find_by_addr(NULL, next);
// prepare FIB flags with prefix length of your destination, i.e. 128 for ::
uint32_t dst_flags = ((uint32_t)128 << FIB_FLAG_NET_PREFIX_SHIFT);
// and finally add the entry to the FIB [5]
fib_add_entry(
&gnrc_ipv6_fib_table, // the FIB table is accessible when
GNRC+FIB is used [6]
iface,
dest.u8, sizeof(ipv6_addr_t), dst_flags,
next.u8, sizeof(ipv6_addr_t), 0,
FIB_LIFETIME_NO_EXPIRE // prevents auto-removing of this entry by
the FIB
);
I haven't tested the code-snips, but in general this should work.
I hope it helps a bit.
Best Regards,
Martin

Betreff: Re: [riot-devel] Adding Fibroute addr on RIOT interface
Hi Kaspar,
Thanks for the tip, but while i was waiting for the reply i did it ;)
Include the "shell_commands.h" and try something like :
char** argum[] = {"fibroute", "add", "::", "via", "fe80::1ac0:ffee:1ac0:ffee"};
_fib_route_handler(5, argum);
This above is just an example with a fixed root ipv6 address.
best regards,
Alessandro

Hi Kaspar,
Thank you for the quick response. Your suggestions were very useful.

[RH] I am targeting the nrf52dk.

[RH]I used the hello-world example, imported the shell module, and new
nordic sdk package. I was able to get the example running, but only with
the compiler optimizer on (ie, -Os). With the gcc optimizer off ( ie,
-O0 ), the hello world example still runs into the same problem. To be
clear, aside from initializing the softdevice handler (in cpu.c), there
is no code in main that interacts with the softdevice.

[RH] Using minicom, I confirmed that the first serial input character
led to the crash. (but only with optimizer off)
>> I'm looking for suggestions on what else to check. Help is appreciated.
> How I love debugging blobs. ;)
[RH] Apologies if the first email was a bit vague.
[RH] I had the optimizer off so that I could use the debugger
effectively. The optimizer was disabled by overriding the CFLAGS_OPT
variable in the example Makefile. I'm using ARM GCC (arm-none-eabi-gcc)
4.9.3 .
Is there some part of the build / OS that assumes/requires optimization
to be turned on? Or do you suppose this is simply a 'size' issue
relating to larger code size with the optimizer off?
Regards,
Robert

Hi all,
I'm trying to automatically set-up network parameters for a RIOT board, i
would like to know how to set a Fibroute address without using the
shell_commands.
Tanks all!

Take a look at the uhcp client code, it sets addresses somewhere.
