get_service_paths jtag_debug returns null

Hello, 

 

I am using a DE0-Nano FPGA and I got the follow error every time that in system-console I write the following tcl script command: 

 

set jtag_path [lindex [get_service_paths jtag_debug] 0]; 

 

jtag_path does not getting any value and fails in successive steps (ie. opening the service etc..) 

 

I did try the same command with different numbers ie. 

set jtag_master [lindex [get_service_paths master] 1]; 

set jtag_master [lindex [get_service_paths master] 2]; etc... without luck 

 

 

Appreciate your inputs, 

 

Thanks
