Hi,
i just tried both and batmand_0.3-beta-rv674 gives a segmenation fault and batmand_0.2-rv502 doesn't start (probably segfault as well). can someone confirm/deny this? has someone a link for a working (with batmand) openwrt-g-freifunk-1.6.x-x.bin/trx ?
are you sure it segfaults or is it simply not running ? Please check "logread -f" to see if batmand is complaining. If you are missing the kmod-tun module batmand will exit and write an error to syslog. Another option is to try the statically linked binary in case some libs changed recently.
Greetings, Marek
