  1. Hello Forum, My first time on a Forum, hope I get the etiquette correct. Recently got my Papilio Duo and a LogicStart wingy, itching to get it all running. Intend to VHDL, not drag and drop...that's the intention anyway. Essentially, being from an electronics background, I like to know what's going on. To that end, I've been wading my way through the plethora of Xilinx datasheets associated with the Spartan-6-LX9. At the moment I have couple of quick questions for the collective forumers The LX9 FPGA is set with M0 =1 and M1 =0, this sets the device in Serial Master Mode so it will get its configuration bit stream from the Flash on power up or if PROGRAM_B is pulled low, so : 1) How does data from the PC get programmed to the Flash? 2) I see other questions relating to the PC software configuring the FPGA directly through the USB port,, am I missing something in the circuit diagram, I cant see how this is possible? Unless there is something pre-configured, pre-programmed that we are shielded from....... hope they're not too stupid questions. Thanks Andrew
