16 years ago --- Quote Start --- cant add target EPCS4 to device chain while in current programing mode --- Quote End --- You apparently tried to access EPCS4 in JTAG programming mode. That can't work, you must set the Quartus Programmer to AS programming. P.S.: I also wondered, if the UP3 reference manual possibly misses an explanation of the different configuration methods and their particular purpose. I think, it basically has it at page 13 of the Version 01 manual.
