Thanks your constant support.

I ran "nrfutil upgrade".
But I can't check because I modified the source code.
I will report back.

The problem has been resolved.
In addition, debug messages (RTT) are now also displayed.

Thank you.

Best regards,
Kato.

Hello,

1. Open a terminal in VS code with the correct toolchain environment selected

2. Run "nrfutil upgrade" from the terminal. Note: upgrades are locked by default but you will get a error message explaining how to disable the lock.

Best regards,

Vidar
