Setting Custom JTAG Frequency - 2023.2 English

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

To set the JTAG frequency, execute the following steps.

1. Right click the connection Hardware Server or Linux TCF Agent you want to add.
2. Click the Add Target Connection button (+) on the toolbar.
3. The Target Connection Details page opens.
4. In the Target Name field, type a name for the new remote connection.
5. Check the Set as default target check-box to set this target as default. The Vitis Unified IDE uses the default target for all the future interactions with the board.
6. In the Host field, type 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.
7. In the Port field, type the port number on which the hw_server is running. By default, the hw_server runs on port 3121.
8. Select Use Symbol Server, if the hardware server is running on a remote host.
9. Click Advanced and select Automatically discover devices ON JATG chain to view the JTAG device chain details.
10. 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.
11. Click OK to save the configuration and create a new target connection. The selected frequency is saved in the workspace and is used to set the frequency before executing a connect command for the selected device.
12. 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.
