Powering target with Segger J-link debugger

Msanad — Tue, 31 May 2022 15:14:19 GMT

Hello,

I'm trying to build a project with the KL03z baord using Kinetis Design Studio IDE, but I'm constantly facing problems when debugging. It keeps on giving the same error dialog "could not connect to target"

Before I was using MCUXpresso, it all was going smoothly and when I have this error message, I just check the "Power target" and "Initialize CPU registers" in the "Debug configuration" panel and this fixes it.

However, with Kinetis Designer Studio, I can't find this feature anywhere ( Power target), so any help or tips will be highly appreciated.

What exact J-Link debug probe are you using? Because in general J-Link probes do not provide the target power.

Hello,
It's the Flasher ARM one, it's the same one used with the other IDE. I just had to permet "Power target", but now I can't do that with Kinetis Design Studio.

the power on/off is an option to the J-Link

Please check your J-Link documentation about the command to be used.

You can add an options like this in KDS as 'other options':
