Vivado Hardware Manager - How to change the 'Auto Connect' cable frequency from default to the slower cable speed?


By default, the Hardware Manager 'Auto connect' option to connect to hardware uses the fastest cable frequency.

How can I change it to a slower speed?


If the slower cable frequency needs to be set, you can start the hw_server with a slower frequency using the following option before launching the Hardware Manager.

For instance, the following will set the default cable frequency to 1Mhz:

hw_server -e "set jtag-default-frequency 1000000"
