Hi KLing4 ,

 

Can you check your JTAG connection first whether it is working or not? (jtagconfig)

 

open Command Prompt/Terminal ---> go to Quartus directory <Quartus installation directory>intelFPGA\18.1\quartus\bin64> ---> run jtagconfig

Hi KLing4,

 

Did the 'jtagconfig' in LINUX is successful?

 

 

And one more thing, did you change the permissions on the the device files? If not, you can try this step:

 

I hope this will help you.

 

Thanks
