2.3 Factory Test Link (P1)

This link is for factory test use only and should not be fitted.

2.4 Flash Boot Image Select Links (P2 1-2 and 3-4)

The Boot Flash is divided into four sections, with all sections accessible all of the
time. This allows for three user boot images to be stored in the Flash, along with a
factory-programmed recovery boot image. Using these links, the four sections can be
swapped around in the memory map, selecting which image is used at boot time.
The state of the links is reflected in
jumpers fitted, the IMP2B boots from the default (Main) boot image; when a jumper
is fitted on either of the links, the IMP2B boots from another boot image, as follows:
