You can now operate at a different frequency supported by the JTAG cable, by setting a custom JTAG frequency.

To set a custom JTAG frequency:

  1. In the Target Connections view, click the Add Target Connection button (). The Target Connection Details page opens.
  2. Specify the name of the new remote target connection, for example test.
  3. Check the Set as default target checkbox to set this target as default. The Vitis software platform uses the default target for all the future interactions with the board.
  4. Specify the name or IP address of the remote host machine. This is the machine that is connected to the target and the hw_server is running.
  5. Specify the port number on which the hw_server is running. By default, the hw_server runs on port 3121. Select Use Symbol Server, if the hardware server is running on a remote host.
  6. Click Advanced to view the JTAG device chain details.
  7. Select the JTAG device chain and click Frequency to open the Set JTAG Frequency page.
  8. From the Set custom frequency drop-down list, select the frequency.
    Note: Current frequency can be the default frequency set by the server or the custom frequency set by a debug client.
  9. Click OK to save the configuration and close the Set JTAG Frequency page. The selected frequency is saved in the workspace and is used to set the frequency before executing a connect command for the selected device.
  10. Click OK to create a new target connection.
    Note: If only one client is connected to the server, the frequency of the cable is reset to the default value whenever the connection is closed. However, in case of multiple clients connected to the server, it is not recommended to perform simultaneous debug operations from different clients.
