nRF5340 tfm sample .. secure_peripheral_tfm

[andywe]

The documentation says ...

The sample displays the following output in the console from the non-secure firmware:

SPP: send message: Success
SPP: process signals: Success

The sample displays the following output in the console from the non-secure firmware:

IRQ: GPIOTE0 count: 0x00000002
IRQ: TIMER1 count: 0x00000001
IRQ: GPIOTE0 count: 0x00000003
IRQ: TIMER1 count: 0x00000002

Whey I build and run the application I see the SPP messages,
but I don not see any of the IRQ messages ... 

I am using the latest version of the nRF Connect SDK and the board is a PCA10095 2.0.0
2022.13
What am I missing here ?

Thank you ... I'm in the middle of writing a TF-M and IoT security course module ... and am working through

the nrf and zephyr TF-M examples ... and making sure I understand all the device tree, linker and KConfig details ...

Getting the code to built and run is just the start ...

Hi, 

Sorry for the delay. 

The IRQ logging output will come from the SPE. This PR https://github.com/nrfconnect/sdk-nrf/pull/9386 fixed the documentation. 

Please see https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/ug_tfm.html#logging on how to get the log from SPE. You could choose one of the solutions to get the log from SPE. To disable the output for the network core and change the pins used by TF-M method, you could create nrf5340dk_nrf5340_cpuapp_ns.conf under the board folder as this file.
