Seeeduino XIAO expansion board on Arduino IDE 2.0 beta - Live Debugger issues

I cannot live debug the Seeeduino XIAO expansion board with Segger J-Link SWD interface, under Arduino IDE 2.0 beta it reported live debugging not available.

I also posted this topic to Arduino forum at HERE.

Please advise.

I know that this is not a answer to your very question to enable XIAO debugging with the Arduino IDE. But if you are willing to try PlatformIO I can confirm that debugging with the J-Link adapter works.

Set platformio.ini to:

[env:seeed_xiao]
platform = atmelsam
board = seeed_xiao
framework = arduino
upload_protocol = jlink
upload_port = jlink
debug_tool = jlink

Then set a breakpoint in your code.
Then start debugging:

StartDebugging

When it stops click ‘Restart’

Restart

When ist stops again click ‘Continue’

Continue

Now it will stop at your breakpoint

Thx RoSchmi for the valuable feedback, I will give a try.
