 +**Worry free GPIO pins(tm):**
 +If you have some DIY project use GPIO pins 18, 19, 20, 21, 22 and 23 without any worries, these pins are not used during booting. Other GPIO pins are not suitable for use if you don't know exactly what you are doing because they are used during boot process (bootstrap).
Based on experiments and knowledge acquired in [[https://forum.openwrt.org/viewtopic.php?id=36471&p=1|the corresponding OpenWRT Forum thread]] (thanks to everyone there :-)), using the kernel interface to GPIOs and a digital multi-meter, it has been possible to locate most of the GPIO pins.
