"Parametric Audio Equalizer for STM32 Discovery Boards" errors by pressing the "Monitor & turn" button.

The errors returned are shown below:

External Mode Open Protocol Connect command failed

Caused by:

DWARF Parser internal error: Parser::describeSymbol xcpDummyDoubleVariable is not a global variable

Component:Simulink | Category:Block diagram error

Unable to connect to the 'STM32F746G-Discovery' target for 'stm32f746gdiscovery_audio_equalizer'.

Component:Simulink | Category:Model error

This project is loaded from "Embedded Coder Support Package for STMicroelectronics Discovery Boards".

If pressing "run" or "Build,Deploy & Start",there is no error returned.

If other modules are commented out and only input and output are left, as shown in the figure, this error message will still be reported. This problem will not appear on the stm32f4 disco development board. Note that stm32f4 uses an additional ttl-233.
