Connection ST-LINK to nRF52

[Hauser]

Hey togehter,

has anyone succeeded setting up a connection between ST-Link and nRF52832? I connected the pins (GND, SWDIO, SWCLK and second try with GND, SWDIO, SWCLK,VTREF,RESET), but Keil as well as the ST-LINK_CLI tell me that no device is available.

For reference, the ST-LINK and nRF51 seems to work:

devzone.nordicsemi.com/.../ devzone.nordicsemi.com/.../

Thanks!

Hello, yes it's still up to date. Im using a custom board and the ST-Link-chip from ST-Nucleo-board.

I connected the following pins:

ST-LINK:GND -> nRF52:GND

ST-LINK:T_JTCK -> nRF52:SWCLK

ST-LINK:T_JTMS -> nRF52:SWIO

ST-LINK:T_NRST -> nRF52:RESET

ST-LINK:T_SWO -> nRF52:Notconnected

Keil as well as the tool STM32 ST-Link Utility detect the ST-Link-chip, but cannot connect.

The nRF52 is powered and running, of course.

Any suggestions?

Thank you!
