No Nios II target connection paths were located error in NIOS II EDS 10.0

[Altera_Forum]

Hi, 

 Using Windows Xp, I upgraded Quartus II (32bit) and Nios II EDS from version 9.1SP1 to 10.0 and now I have a problem in connecting to the NIOS II processor through the JTAG USB Blaster.   Running the configuration in NIOS II EDS, when I go "run as --> Nios II Hardware", in the "Target Connection" Tab I get the message:   " no nios ii target connection paths were located. check connections and that a nios ii .sof is downloaded."    This happens even with the Terasic Cyclone III FPGA starter kit board downloading their reference design "cycloneiii_3c25_start_niosii_standard.sof" and creating an "Hello World" application program.   Is there anybody who had the same problem with NIOS II EDS 10.0 and can help me?   Michele

Hi, 

 I just fixed my problem using the NIOS II 10.0 Command Shell. I report what happened as someone could find it useful:   I tried to connect to the NIOS II processor using:    nios2-terminal    but the shell prompted that I had to specify the --cable option as it appeared I had more than one cable active. So I enumerated my JTAG cable using:   jtagconfig --enum    and I discovered that it was seeing a ByteBlaster cable that I am actually not using:   bash-3.1$ jtagconfig --enum 1) ByteBlaster [LPT1] Unable to lock chain (Bad port name) 2) USB-Blaster [USB-0] 020F30DD EP3C25/EP4CE22   I deleted this cable by using the command:   jtagconfig --remove 1    and now I can see my NIOS II processor and run my firmware on NIOS II EDS again! :)    Michele
