Build the sample using west ... like so ...
west build -b nrf5340dk_nrf5340_cpuapp_ns -p=auto --force -d "C:\nRF-Projects-2\psa_crypto\" ".\zephyr\samples\tfm_integration\psa_crypto\"
west flash,
connect to PuTTY console and reset ...
output is shown below ... my question is how to set up the example so that the Already exists errors are not displayed .. the tf-m startup details are displayed.
*** Booting Zephyr OS build v3.1.99-ncs1 ***
