Hi Marta,

I'm truly sorry for this to have taken so long. Attached is a working version on the secure SPI sample: devzone.nordicsemi.com/.../spi_2D00_rallare_2D00_secure_2D00_working_2D00_NCS130.zip

First off all the overlay files were wrong, I completely missed that:

The name of the overlay was wrong. The overlay file should be named: nrf5340pdk_nrf5340_cpuapp.overlay (the same goes for non-secure)
The status field should "okay" and not "ok". See below

&spi1 {
	compatible = "nordic,nrf-spim";
	status = "okay";
	mosi-pin = <4>;
	miso-pin = <10>;	//<5>;
	sck-pin = <6>;
};

&spi2 {
	status = "disabled";
};

&i2c1 {
    status = "disabled";
};

The issue with board overlay file name will cause the compilation to not set correct SPI_1 configuration, leading to it not finding SPI_1 and giving the error "Could not get SPI_1 device". Adding CONFING_RESET_ON_FATAL_ERROR=n will stop the device from going into boot loop.

Here is the current project configuration I used:

CONFIG_SERIAL=y

CONFIG_UART_INTERRUPT_DRIVEN=y

CONFIG_LOG=y
CONFIG_LOG_IMMEDIATE=y

# SPI
CONFIG_SPI=y
CONFIG_SPI_1=y

CONFIG_MAIN_STACK_SIZE=4096

CONFIG_RESET_ON_FATAL_ERROR=n

Let me know how it works for you!

Kind regards,
Øyvind

Hi Marta,

My apologies, I did write an answer to you on Monday, however, it was never sent.

I am able to reproduce the issue but have not found the root cause. Will discuss it with our developers and get back to you.

Kind regards,
Øyvind
