连接DA14580 (HJ580LAXP Module) via SWD in SmartSnippets Toolbox -> No known chip found

Hello lovely Dialog team,

我去t a problem connecting my HJ580LAXP module via SWD (using Segger J-Link Lite) to my PC. Using UART everything works fine...

Connected:

SCK -> SCK

SWD -> SWD

3.3V -> Vcc

As I read in the forum it is possible to REprogram the OTP via SWD as long the "JTAG enable flag" is set to "enable". So that I can overwrite the program on OTP, is that right?

Now when I try to download my .hex file to the boards Ram I get the following error message:

I already tried different modules and tried to find the Chip via ULING Pro (Keil) in Keil uVision, same problem. No chance to find the Chip in any way. Do you maybe have an idea, what else I could try?
