Hello Everyone,
I want to program the BMD-300 with the nRF52 Preview Development Kit. I have connected:
BMD-300 -> nRF52-DK
SWDIO -> SH_SWDIO (pin #4) on P20
SWDCLK -> SH_SWDCLK (pin #5) on P20
VDD -> SH_VTG (pin #3) on P20
GND -> SH_GND_DETECT (pin #8) on P20
The BMD-300 is powered by a generator (3V).
JTAG connector: www.tag-connect.com/.../TC2050-IDC-NL Datasheet.pdf
Now, when I use nRFgo Studio, it doesn’t work: Following Text is written:
Latest motherboard firmware: 7000 Boards connected: No boards connected.
When I use µvision (Keil), it doesn’t work too. Following Text is written:
JLink – Cortex-M Error No Cortex-M SW Device Found
µVision Error: Flash Download faild – Target DLL has been cancelled
Build Output:

If someone knows, what I have done wrong, I would be happy, if he/she could help me.
Thank you
