Zephyr sample code for accessing NOR flash through SPI APIs

snowuyl

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?

    Hi,

    There is already a sample in Zephyr for SPI-NOR flash,

    regards

    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 = [

    I try to use the command (west build -b nrf9161dk_nrf9161) to build sample you suggested. But west build failed with error: '__device_dts_ord_113' undeclared (first use in this function); did you mean '__device_dts_ord_13'?
