Dear Sir:
  I can't connect a STM32F427IIT6 custom board via ST-link (SWD) of STM32F407 discovery board . Neither through uVision 5.0 nor through ST-link Utility (I use STM32 ST-link utility v3.6.0, STLinkUSDDriver.dll v4.3.4.0, ST-link-CLI.exe v2.2.0).
  
  When try connecting using ST-link utility, it will report:


  No target connected
  Can not connect to target!
  Please select "Connect Under Reset" mode from Target->Settings menu and try again.
  If you're trying to connect to a low frequency application , please select a lower SWD Frequency mode from Target->Settings menu.



  The question is:
  
    Q1: Can STM32F407 discovery ST-link be used for STM32F427 body? Or Only STM32F427 discovery board can be connected with!
    Q2: If yes for STM32F407 discovery board, what ST-link FW version is fine to used on STm32F427 device?
    Q3: What hardware should I check when connected by SWD? Now on discovery board, I remove two jumps of CN3, and connect only pin 2~4 (SWD_CLK, GND, SWD_DIO) of CN2 to (PA14, GND, PA13) of STM32F427 custom board.
