The following is an example XSCT session that demonstrates selecting a target based on target properties. It shows how to connect to the Cortex® -A9 processor of the second device when multiple devices are connected in a JTAG chain (xc7z020 and xc7z045).

# connect to hw_server
xsdb% conn -ho xhdbfarmrkh1

# check the jtag targets connected, the IDs listed with jtag targets are called node IDs
