Security components
Implementation Defined Attribution Unit. The IDAU is implemented with the System Protection Unit and is used to define secure and non-secure memory maps. By default, all of the memory space (Flash, SRAM, and peripheral address space) is defined to be secure accessible only.
Secure boot.
Programming and Debugging
innblue21 supports the Armv8m Security Extension, and by default boots in the Secure state.
Building Secure/Non-Secure Zephyr applications
The process requires the following steps:
Build the Secure Zephyr application using
-DBOARD=innblue21andCONFIG_TRUSTED_EXECUTION_SECURE=yin the application project configuration file.Build the Non-Secure Zephyr application using
-DBOARD=innblue21/nrf9160/ns.Merge the two binaries together.
When building a Secure/Non-Secure application, the Secure application will have to set the IDAU (SPU) configuration to allow Non-Secure access to all CPU resources utilized by the Non-Secure application firmware. SPU configuration shall take place before jumping to the Non-Secure application.
Building a Secure only application
Build the Zephyr app in the usual way (see Building an Application
and Run an Application), using -DBOARD=innblue21.
Flashing
Follow the instructions in the Nordic nRF5x Segger J-Link page to install and configure all the necessary software. Further information can be found in Flashing. Then build and flash applications as usual (see Building an Application and Run an Application for more details).
Here is an example for the Hello World application.
First, run your favorite terminal program to listen for output.
$ minicom -D <tty_device> -b 115200
Replace <tty_device> with the port where the nRF9160 innblue21
can be found. For example, under Linux, /dev/ttyACM0.
Then build and flash the application in the usual way.
# From the root of the zephyr repository
west build -b innblue21 samples/hello_world
west flash
