TF-M Hello World¶
A simple sample based on Hello World that demonstrates adding Trusted Firmware-M (TF-M) to an application.
Overview¶
This sample uses the Platform Security Architecture (PSA) API to calculate a SHA-256 digest and the TF-M platform read service to read two FICR registers. The PSA API call is handled by the TF-M secure firmware.
Requirements¶
The sample supports the following development kits:
Hardware platforms |
PCA |
Board name |
Build target |
---|---|---|---|
PCA10095 |
|

Building and Running¶
This sample can be found under samples/tfm/tfm_hello_world
in the nRF Connect SDK folder structure.
See Building and programming a sample application for information about how to build and program the application.
Testing¶
After programming the sample, the following output is displayed in the console:
Hello World! nrf5340dk_nrf5340_cpuapp
