This feature of the AMD Vitis™ environment allows you to run and debug application projects, program the bitstream/PDI, and program the flash using multiple JTAG cables or multiple devices on a single JTAG chain. The main use cases are as follows:
- Multi-cable
- This use case assumes you have more than one board connecting to the system
and you want to work on all of the boards. The following is a multi-cable
target connection view. Regarding target connection, refer to Target Connections.
- Multi-device
- This use case assumes you have multiple devices in a JTAG chain and you want to work on all of the devices. The following is a multi-device target connection view. Regarding target connection, refer to Target Connections.

Debugging an Application with Multi-cable or Multi-device
- Navigate to the debug launch configuration file (refer to Launch Configurations for details).
- Click Select beside the
Device field.Figure 2. launch.json Tab
- Deselect Auto Detect
Figure 3. Select PL and PS Device Screen
- Select the PS and PL device in this dialog according to your requirement.
- Click Select and Start to start debugging.
Programming a Device Using a Multi-Device/Multi-Cable Setup
- Go to →
- To select a device from the multiple cable or multiple device setup, click the Select button to the right of the Device field.
- Choose the appropriate device or cable from the drop down menu and click
Program to program the FPGA/PDI file.Note: If the device status is Auto Detect, the Vitis tool automatically picks up the first device or cable from the list.Note: Use the same method to choose the PS and PL device when programming a flash.
