I am trying to talk to my NUCLEO-F103RB board via my st-link/V2 B202016 but so far I have not been able to.
Below is an image of my connection
Below is an image of my jtag connect
I have connected the pins in following order
JTAG_Pin 19 -> (Nucleo Board) Header CN6, PIN 4 (This supplies the nucleo board with 3.3V) (I've measured this out and it does provide 3.3V.
JTAG Pin 20 -> (Nucleo Board) Header CN6, PIN 6 (This is ground)
JTAG Pin 15 -> (Nucleo board) Header CN6, PIN 3 (This is the NRST pin).
JTAG Pin 9 -> (Nucleo Board) Header CN7, PA 13 (TCK_SWCLK)
JTAG Pin 7 -> (Nucleo Board) Header CN7, PA 14 (TMS_SWDIO) (Not shown in picture but i have connected it now)
When i try and connect i get the following message

Hard to see the ST-LINK end looks like connecting to 5 & 7, perhaps better angle, better resolution?
Check the solder bridge related to the NRST from the on-board
Check voltage at IDD jumper

Ty Tesla for the reply, i have attached a clearer picture of the stlink (i hope)
I believe the NRST is fine.
What is the IDD jumper? I have a voltmeter so i can check that quickly.
