Error (209040): Can't access JTAG chain

Hello, 

 

I am trying to use the DE0-Nano board with Quartus Prime 18.0.0 (Linux) and I am experiencing problems when I try to load the .sof file to the board. 

The loading always fails and the only output message from console is: 

 

Error (209040): Can't access JTAG chain Error (209012): Operation failed  

 

It's likely to be a problem related to the software itself or some bad configuration, because I remember I used the board a few years ago, but now it's impossible... 

 

The "Load" LED beside the "Power" LED turns on when I try to upload the file, but always fails.. 

 

Do you have any helpful suggestion to solve this problem ? 

Many thanks in advance. 

 

Regards,

SOLVED 

 

The problem was due to the fact the bin path of the installation directory was not included into the PATH environment variable, so Quartus could not launch the jtag binary files.
