平台:Vivado2018.3
在调试vivado在线debug过程中,发现无法显示波形。
报错如下。
ERROR: [Wavedata 42-472] WCFG parsing ERROR:
Fatal Error at file E:/githome/xxxx/hw_1/wave/hw_ila_data_1/hw_ila_data_1.wcfg, line 1, char 1
Message: invalid byte '?' at position 2 of a 3-byte sequence
ERROR: [Labtools 27-1832] create_wave_config not a supported tcl command in labtools hardware mode. Default wave configurations are automatically created when triggering an ILA core.
解决办法
Use below command in TCL.
display_hw_ila_data -reset
This error happen because of not proper saving og ila_data and retrying to recover it.
