Hi all I'm still using a Spartan3e starter kit for various issues (it's aged but still very usefull). For my current project i need to program the Spartan using an external uP that i want to connect to the connector for extended JTag (J28). Now i become unsecure how this should work. The s3e1600 board provides an integrated JTag programmer. Unfortunally it is not documented in the schematic's since it is an Xilinx proprietary design. Moreover J28 does not provide anything like the PGND signal, found i.e. at the Xilinx platform cable USB II. Hence the S3e1600 board can't detect a connected JTag
