programming a custom kl03 device with jlink debugger

Hello

I want to move my software from my frdm-kl03 to a custom board with a JLINK EDU debugger.

This is what i get when starting gdb

And it stays there without doing anything, it seems everything is OK except it can't start the target.

Thanks for helping

Hi,

- first, to avoid old association, please create a new workspace folder, see how it can work with your Jlink?

- if problem persists, I suggest you download the latest J-Link software package

https://www.segger.com/jlink-software.html

see how it works?

- with frdm-kl03 board, you also use Jlink OpenSDA interface? can you launch KDS debugger with Jlink Open SDA interface?

-JLINK EDU is Segger product, I suggest you also post this question to Segger forum:

Main Page - SEGGER Forum

Have a great day,
Jennie Zhang
