So our new hardware guy who is being managed by our lead embedded developer had the task of designing me an expansion board for my Linux board. The Linux board uses the 40 pin expansion like the raspberry, bananna and orange pi family and as you all know there are many different types of expansion boards for this.
I said at the start come to me and tell me what you want to connect to before deciding which pin you connect to so it is less work for me with Linux board configs and drivers.............
No no no we will sort it all... erm.....
So today they come ask me if they can use an SPI port for GPIO and I am like erm... why there is plenty of GPIO...
It turns out they have been designing the board based on the pin outs of an expansion board and not the actual connector of the Linux board.. I mean seriously WTF!
