cmod s6 programming while in breadboard

[gpiesinger]

Can the cmod s6 be programmed using the USB connector and impact tools when the cmod s6 module is plugged into my unpowered breadboard?  That is, are the user output pins placed in high impedance when powered from the USB cable and being programmed? 

Or, should my breadboard be powered when programming using the USB cable?

That is, can the cmod s6 module be programmed without removing it from my breadboard circuit?  Thanks.

Hi @gpiesinger,

I found a thread on stack exchange here that discusses that state the I/O pins on a spartan 6 during configuration.  Here is the Spartan-6 FPGA SelectIO Resources User Guide. On page 45 it discusses I/O Pins During Power-On and Configuration. Here is the Spartan-6 Family Overview. 

cheers,
