No problem Marcus. The chart is a spreadsheet, so click on the tab at the top to see the second bus
I have finished checking the I/Os on the Pi P5+ bus, and all the expected I/Os work. i.e. all the pins are controllable except for power, gnd, the ethernet ones and the SPDIF pin, so a total of 9 unique I/Os, and the bottom two shared with the Pi-2 bus header.
I threw this quick script together to do the tests... just give it the GPIO export number, and it will attempt to set the pin up, and toggle it five times (led blinky ). I suppose I should be nice and build the python script functionality into it, and also a 'capture current state and restore when finished' process... maybe... someday
