How Connect Nucleo 411 Board to a JTAG Interface

(Juergen Rieger) #1

Hello …
I have an IAR IDE and I want connect the J-Link (JTAG Connector) to the Nucleo-F411RE Board. Can I do this?
If that is possible, is there a description of how to do that?
regards jurgen

ST uses different pin layout on the NUCLEO boards for the debug interface, but you can convert the pins to fit JTAG header with a little soldering… See https://gnu-mcu-eclipse.github.io/developer/j-link-stm32-boards/

In my case I only had a success after I:

  • I disconnected the ST-Link adapter from the NUCLEO board.
  • I made the following connection to the NUCLEO-Board:


Pin 15 (TCK) <–> Pin 9 (SWCLK / TCK)
Pin 20 (GND) <–> Pin 6 (GND)
Pin 13 (TMS) <–> Pin 7 (SWDIO / TMS)
Pin 14 (NRST) <–> Pin 15 (nRST)
Pin 16 3V3 <–> Pin 1 (VTref)


Pin 31 (SWO) <–> Pin 13 (SWO / TDO)
