I would like to access NOR flash through SPI APIs on nRF5340 device. Does Nordic provide Zephyr sample code for accessing NOR flash through SPI APIs?

Thanks for your reply! The sample that you provided is using nordic,qspi-nor. Could you provide another sample for jedec,spi-nor.
&spi3 {
cs-gpios = <&arduino_header 16 GPIO_ACTIVE_LOW>, /* D10 */
<&gpio0 25 GPIO_ACTIVE_LOW>;
mx25r64: mx25r6435f@1 {
compatible = "jedec,spi-nor";
status = "disabled";
reg = <1>;
spi-max-frequency = <8000000>;
label = "MX25R64";
jedec-id = [c2 28 17];
sfdp-bfp = [

Procedure to reproduce this issue are as follows.
1. cd ~/ncs/v2.4.0/zephyr/samples/drivers/spi_flash
2. west build -b nrf9161dk_nrf9161
~/ncs/v2.4.0/zephyr/samples/drivers/spi_flash$ west build -b nrf9161dk_nrf9161

Hi,
Ah yes, you are correct in that it uses QSPI. It's because the onboard flash supports QSPI and not SPI. Are you going to use the onboard external flash? Or do you have a stand alone onboard flash device?

Jared

Thanks for your reply! I am using the onboard external flash. I found C:\ncs\v2.4.2\zephyr\samples\drivers\jesd216 is what I want.
