On my OpenWrt system, the corresponding log entry says:

/dev/net/tun is a Linux tun/tap device (tun mode)

I don't know if that is a real problem.  And I don't know how the tun
device gets created -- I don't remember having to do anything special
(but it was a long time ago when I set it up).

However, I do start tinc using "/etc/init.d/tinc start", not by running
tincd directly.

That doesn't look good!

My /etc/tinc/NETWORK/tinc-up file contains:

#!/bin/sh
ifconfig $INTERFACE 1.2.3.4 netmask 255.255.0.0
/etc/init.d/firewall reload

(with the real IP address for this node of the VPN instead of 1.2.3.4,
of course).

I do remember some work being needed to get the firewall set up
correctly.  But you aren't getting that far.

I would support Maxim's suggestion: make sure you have a simple tinc
network working on ordinary Linux systems first, to make sure you know
how the keys and addressing work.
