Message: No debug cores, when trying to use ILA

tcl console上显示

WARNING: [Labtools 27-3361] The debug hub core was not detected.
Resolution:
1. Make sure the clock connected to the debug hub (dbg_hub) core is a free running clock and is active.
2. Make sure the BSCAN_SWITCH_USER_MASK device property in Vivado Hardware Manager reflects the user scan chain setting in the design and refresh the device. To determine the user scan chain setting in the design, open the implemented design and use 'get_property C_USER_SCAN_CHAIN [get_debug_cores dbg_hub]'.
For more details on setting the scan chain property, consult the Vivado Debug and Programming User Guide (UG908).
WARNING: [Labtools 27-3403] Dropping logic core with cellname:'u_ila_0' from probes file, since it cannot be found on the programmed device.

Hi, @xiangxiang ,

Please try to connect the clock of dbg_hub to an free-running clock. (For example: a clock from FPGA port).

Ex: connect_debug_port dbg_hub/clk [get_nets <clock_net_name>]

如果ILA的连接没有问题,dbg_hub连接的确实是一个理论上是free running的时钟的话(你可以按照hongh给出的AR#64764里第一条solution提到的内容检查dbg_hub连接的是哪个时钟,用户没有干预的情况下这个时钟是工具自动选择的),这个问题常见的原因是,这个时钟在板子上的时钟质量不好。比如板子上这个时钟就没起来,提供时钟的插槽没插紧等等。可以在板级用示波器查一下时钟来源是否有问题。
