What does this mean? The debug hub core was not detected at User Scan Chain 1 or 3

Question

This warning appears every time I connect to a target in the hardware manager.

INFO: [Labtools 27-1434] Device xc7a35t (JTAG device index = 0) is programmed with a design that has no supported debug core(s) in it.

WARNING: [Labtools 27-3123] The debug hub core was not detected at User Scan Chain 1 or 3.
Resolution:
1. Make sure the clock connected to the debug hub (dbg_hub) core is a free running clock and is active OR
2. Manually launch hw_server with -e "set xsdb-user-bscan <C_USER_SCAN_CHAIN scan_chain_number>" to detect the debug hub at User Scan Chain of 2 or 4. To determine the user scan chain setting, open the implemented design and use: get_property C_USER_SCAN_CHAIN [get_debug_cores dbg_hub].

 

Thanks
