PP12 AUD_2V5 (for PWM audio drivers)
PP13 Goes from 3V3 to 2V on ACT activity
PP21 RUN signal (reset)
PP22 Goes from 3V3 to 2V on activity of green (link) ethernet jack LED
PP23 Goes from 3V3 to 2V on activity of yellow (speed) ethernet jack LED
PP27 VBUS (USB 5V power)
PP28 ETH_CLK (25.000 MHz)
PP35 GPIO6 of LAN9514
PP36 GPIO7 of LAN9514
None of these test points has ever been documented to be useful for anything that isn't already provided via the I/O connectors where they're duplicated. Of what possible use are the Ethernet clock, GPIOs for the LAN9514 or CSI, or VC_TMS, VC_TRST_N, VC_CLK, VC_TDI, VC_TDO, etc., especially where the associated software isn't accessible at the source level that runs at the binary level on the BCM-2835/6? As the supermarket tabloid "The National Enquirer" states in its ads, "Enquiring minds want to know!"

In theory, theory & practice are the same - in practice, they aren't!!!
