Hi Philipp,
Unfortunately, this is a known issue. The only workaround available right now is increasing RAM. Which I guess is not possible for you with your ARM device.
Matthias Schiffer has been working on a solution:
https://lists.open-mesh.org/pipermail/b.a.t.m.a.n/2015-June/013339.html
Not sure whether he would still be inclined to work on that after the lack of feedback he had gotten or whether he still has the time for that.
Regards, Linus
PS: How much (free and in total) RAM does your device have, which device is it exactly? Just that others know how much RAM is needed to read from debugfs with a 300+ nodes setup right now.

Hi all,
I've got this error with
# batctl -v batctl 2016.0-4-g7a3d563 [batman-adv: 2016.0-83-g884fb2d]
on
# uname -rmpio 3.4.107-01996-g67bdc52 armv7l ARMv7 Processor rev 4 (v7l) sun7i GNU/Linux
I know the kernel is old, I can take a recent one if needed, but maybe this is not necessary.
The module has been compiled with CONFIG_BATMAN_ADV_DEBUG=y CONFIG_BATMAN_ADV_BLA=y CONFIG_BATMAN_ADV_DAT=y CONFIG_BATMAN_ADV_NC=y CONFIG_BATMAN_ADV_MCAST=y CONFIG_BATMAN_ADV_BATMAN_V=n
and batctl as usual but without stripping. The problem occurs while calling “batctl o”. There should be an output of 336 lines …
Please tell me if you need more information. Thanx in advance and thank you for B.A.T.M.A.N. advanced.
Best regards, Philipp
