Debug issue SWD

dk3 — Wed, 30 Jul 2025 01:57:15 GMT

I am seeing the following issue when trying to debug/flash the wireless_uart_freertos compiled file to my KW45B41z-EVK where there are no SWD devices available. All the pins are set to the following ones attached in image for internal MCU-Link. Any help here on being able to debug successfully would be great.

Hello, hope you are doing well,

Could you please help us sharing a picture of both KW45B41Z-EVK and the MCU-Link to see the configurations on the jumpers?

Could you help us confirm if you can flash any program on the board before?

Could you please try deleting the launch configurations of the project from previous debug sessions [.launch file]?

Best Regards

Luis

Hi Luis,

Attaching the jumper configurations as well as MCU-Link configurations. I have deleted the .launch as well. I have not been able to flash any boards previously, this is my first time.

Hello,

Could you help us following the getting started guide from Chapter 1 to 3 please Getting Started with the KW45B41Z Evaluation Kit | NXP Semiconductors, to verify if the board can be flashed.

After that, test the "wireless_uart_freertos" example from the SDK without modifications and create a debug session.

The Bluetooth Low Energy Demo Applications User’s Guide Chapter 5.12 will guide you on how the application needs to be working.

Let me know if this information is useful for your requirements and please let me know your findings, and if you have any further question, please do not hesitate to ask.

Best Regards

Luis
