Feed ist per default falsch in der /etc/opkg.conf - ar71xx statt ar71xx_mikrotik. Nach Umstellung:

Lösungvorschlag:

Das postinst-Script von kmod-batman-adv verwendet wohl insmod, welches zu blöd ist die Abhängigkeit aufzulösen - vielleicht können wir ja modprobe verwenden.

root@f2a-core-rt:~# rmmod batman_adv
root@f2a-core-rt:~# rmmod crc16

root@f2a-core-rt:~# insmod /lib/modules/3.10.49/batman-adv.ko
kmod: failed to insert /lib/modules/3.10.49/batman-adv.ko
root@f2a-core-rt:~# 
root@f2a-core-rt:~# modprobe batman-adv
root@f2a-core-rt:~# lsmod | grep batman
batman_adv            107888  0 
crc16                    944  1 batman_adv
libcrc32c                496  1 batman_adv

Achso, quick & dirty Workaround: batman-adv einfach auch bei ar77xx_mikrotik defaultmäßig einbauen - dann wird es beim ersten booten korrekt geladen. Daher tritt der Fehler bei den anderen Architekturen auch nicht auf (ar77xx, mpc88xx)...

[booo]

Das postinst-script sollten wir wahrscheinlich im Upstream Repo fixen (http://github.com/openwrt-routing/packages).

Wenn batman-adv teil von allen anderen default images ist, dann sollten wir das angleichen. Problematik mit dem insmod und insbesondere der falschen Url besteht weiterhin.

[andrenarchy]

batman-adv will be in the default images as of #187. The opkg feed bug is tracked in #185, so I'm closing this.
