hi,
I finally solved it like this:

1) I programmed the nrf9160dk_nrf52840 section with a simple 'hello word' program by adding the following overlay.

/ {
    board-control {
            external_flash_pins_routing: switch-ext-mem-ctrl {
                    compatible = "nordic,nrf9160dk-optional-routing";
                    control-gpios = <&gpio0 19 GPIO_ACTIVE_HIGH>;
                    status = "okay";
            };
    };
};

this enables the pin that switches control of the QSPI_Flash from the 52840 side to the 9160 side.

2) I programmed the 'spi_flash' example using board revision version '0.14.0' and changed the code slightly in 'main.c':

void main(void)
{
	const uint8_t expected[] = { 0x55, 0xaa, 0x66, 0x99 };
	const size_t len = sizeof(expected);
	uint8_t buf[sizeof(expected)];
	const struct device *flash_dev;
	int rc;
    /* modify */
	flash_dev = DEVICE_DT_GET(DT_NODELABEL(mx25r64));
	/* end modify */

	if (!device_is_ready(flash_dev)) {
		printk("%s: device not ready.\n", flash_dev->name);
		return;
	}
	 .......
}

------

now it works perfectly.

Thank you

Babos

Hi,

in theory, if I use the same source for the 52840 it should already work.
I try tonight.
Thank you

Hi,

Yes, correct! It needs to be enabled by the board-controller(nrf52840 on the nRF9160-DK). See these links:

hi,
Yes, I already tried but I have the same error.
I think this could be the problem:

If you are building with west:

use nrf9160dk_nrf9106_ns@1.0.0 as build target

If you are building with VS Code nRF Connect extension, set revision to 0.14.0:

Ok, the 9160dk version is:

PCA10090 1.0.0, 2020.05

babos — Mon, 30 Jan 2023 10:33:08 GMT

okay Sigurd,
I'll check and then let you know.
Thank you

Hi,

Make sure to specify the board revision when building. See this link:
