The 'NN' should be 'II', but that IS NOT the source of your problem. I recommend you turn on Win32::API's undocumented debug logging, before calling new(). To do this, put "$Win32::API::DEBUG = 1;" before new(). Alot of console logging will be outputted. Either 'JtagWriteReg' is not exported, or jtagvsdll is a 32 bit DLL being loaded into a 64 bit process, or jtagvsdll.dll does not exist.
