Hey William, yea i read this article and wonder if there is logic in the Xilinx for wiring the LEDs to the known GPIO-Pins.
It would be really nice to get some Informations (from soekris?) what the current bitstream contents. Its nice that they promote a box with "user programmable" fpga, but the lack of information how to use it in an appropriate way without bricking something is bad :\ Thanks for replay and i hope we will get soon more informations about how to use! Another Idea, wouldn't it be possible to reflash the Xilinx on runtime in a similiar way the boot up routines does? Maybe thats a more secure way to play arround without messing thinks if we get no proper Informations?
