Hi John,
I just tried here and don't see the problem. I can see this printed on UART:

If you test with helloworld example do you see anything printed on UART ? Note that usually there are 3 virtual UART ports created and you need to select the correct one (usually the first).
Have you tried to step into the code and check if anything wrong ?
Hi:
Test helloworld It's OK.But nvs example still has COM11 no output.

Do you have ncs v2.1.1 test?(\v2.1.1\zephyr\samples\subsys\nvs)
source code:

After using v2.1.2 version, the problem is solved.
Maybe the v2.1.1 version is not completely downloaded.
