change the clock frequency of the USB-Blaster II download cable

Honored Contributor I

Hi everyone,  

I wanna change the clock frequency of the USB-Blaster II download cable from 24MHz to 6MHz and I saw they said we have to use the command: 

jtagconfig --setparam <cable> JtagClock <frequency> 

but could someone tell me what should i do exactly? 

Because when i try it in the terminal, it shows me jtagconfig --setparam 1 JtagClockThMjtagconfig: command not foundEven when i try to use that command sudo apt-get install jtagconfig 

[sudo] password for jiang:  

Reading package lists... Done 

Building dependency tree  

Reading state information... Done 

E: Unable to locate package jtagconfig 




Thank you in advance

jtagconfig it's located in <quartus-intallation-path>/bin/ . Move to this folder and then run ./jtagconfig. Be sure that jtagd is running.
