No STM32 target found! If your product embeds Debug Authentication, please perform a discover

I am using STM32H747I-DISCO board and got this error when I try to connect in STM32CubeProgrammer Error: No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug Authentication.

Please anyone suggest how to fix this problem.

Hi @Pavankumar1_ 

Could you check the following point:
- The USB to micro used is a data transfer and not a simple charging cable?
- USB connector CN2 is used to connect the embedded STLINK-V3E to the PC?
- JP6 is in position on STlk? 
You can refer to the UM2411 Table 3.

I have done all the above steps but getting same error as above "Error: No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug Authentication".

Could you share a screenshot of STM32CubeProgrammer GUI and especially the right view that showing ST-Link Configuration (when you' are trying to connect to the STM32H747I-DISCO)
Does the board contain a firmware in flash memory?

You've done the R192 recovery sequence described in 5.2.3?
