1. Move the JP2 jumper on the NUCLEO-N657x0-Q board to the "top" position.

2. Use the STM32 Programmer v2.20.0 software

3. Set (mouse click on) the connection to "ST-LINK" in the upper right hand ("blue") window of the STMCubeProgrammer software.

4. MOST IMPORTANT: Push the "Reset" button on the lower right corner of the NUCLEO-N657x0-Q board. (It is to the right of the Ethernet connector - below the LED2, LED3 etc..)

5. Click on "CONNECT" in the upper right hand corner of the STMProgrammer software.

It works! The STMProgrammer software shows "Connected" and the Log window shows a long message that ends with (2nd to last line) a light green line "Data read successfully"
