The MTX-1 board (AMD Alchemy) is using a similar GPIO-based watchdog: http://lxr.linux.no/#linux+v3.1.4/drivers/watchdog/mtx-1_wdt.c such a driver could be made generic by the way. > > (I've also posted to the forum: > <https://forum.openwrt.org/viewtopic.php?pid=150278#p150278> but didn't > get any answers, hope it's better suited here...) > > Regards, > Mathias Adam > _______________________________________________ > openwrt-devel mailing list > openwrt-devel@lists.openwrt.org > https://lists.openwrt.org/mailman/listinfo/openwrt-devel -- Florian _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
