I have a SCANSTA112 device between a FlashPro Lite programmer and a ProASIC Plus device I am trying to program. My programming plan is to first place the SCANSTA112 into full transparent mode. Then I should be able to connect up my FlashPro Lite programmer and everything should work as if the SCANSTA112 device was not in the scan chain. However, I can't seem to get the SCANSTA112 to behave as a true pass-thru device with the FlashPro Lite programmer. My TCK signal gets through as expected, however my TMS, TDI, and TDO signals do not propagate through the SCANSTA112 device as expected. Sometimes the data on TMS, TDI, and TDO lines up between the master input port and the local scan port, but other times I can see clear discrepancies in the data from input to output.
