The code I supplied should run as-is on the nRF52840-DK with no changes, does it work then?

Are you trying to interface your flash device from the nRF52840-DK in this case? I can see the supply voltage is different, so I don't know how this would work.

Hello,Kenneth,

thanks for your reply.

i' have change the pin in overlay file.

&uart0 {
	status = "okay";
	label = "UART_0";
	current-speed = < 0x1c200 >;
	tx-pin = < 0x08 >;
	rx-pin = < 0x28 >;
	rx-pull-up;
	rts-pin = < 0xFFFFFFFF >;
	cts-pin = < 0xFFFFFFFF >;
};
&uart1 {
	status = "disabled";
	label = "UART_1";
};
&spi2 {
	status = "disabled";
	label = "UART_1";
};
&egu2 {
	status = "disabled";
};
&egu3 {
	status = "disabled";
};
&egu4 {
	status = "disabled";
};


&qspi {
	status = "okay";
	sck-pin = < 0x13 >;
	io-pins = < 0x15 >, < 0x14 >, < 0x18 >, < 0x17 >;// MISO=IO0  MOSI=IO1  IO2  IO3
	csn-pins = < 0x16 >;

	GD25LQ32E: GD25LQ32E_@0 {
		compatible = "nordic,qspi-nor";
		reg = < 0x0 >;
		writeoc = "pp4io";
		readoc = "read4io";
		sck-frequency = < 0x7a1200 >;
		label = "GD25LQ32EEIGR";
		jedec-id = [ C2 28 17 ];
		sfdp-bfp = [ E5 20 F1 FF FF FF FF 03 44 EB 08 6B 08 3B 04 BB EE FF FF FF FF FF 00 FF FF FF 00 FF 0C 20 0F 52 10 D8 00 FF 23 72 F5 00 82 ED 04 CC 44 83 68 44 30 B0 30 B0 F7 C4 D5 5C 00 BE 29 FF F0 D0 FF FF ];
		size = < 0x4000000 >;
		has-dpd;
		t-enter-dpd = < 0x2710 >;
		t-exit-dpd = < 0x88b8 >;
	};
};

the pin PWR_1V8 voltage is 1.8V.(Measure with a multimeter)

Best Regards

Can you try this one? You likely need to change the overlay file to work with your board.

Hi,

thanks for reply, wo read your link.

i can runing with mx25r64 flash on DK,it's work well.

but change to GD25LQ32EEIGR,log:flash devece not found!

&qspi {
	compatible = "nordic,nrf-qspi";
	#address-cells = < 0x1 >;
	#size-cells = < 0x0 >;
	reg = < 0x40029000 0x1000 >, < 0x12000000 0x8000000 >;
	reg-names = "qspi", "qspi_mm";
	interrupts = < 0x29 0x1 >;
	status = "okay";
	label = "QSPI";
	sck-pin = < 0x13 >;
	io-pins = < 0x14 >, < 0x15 >, < 0x16 >, < 0x17 >;// MISO=IO0  MOSI=IO1  IO2  IO3
	csn-pins = < 0x11 >;	// CS#

	mx25r64: mx25r6435f@0 {
		compatible = "nordic,qspi-nor";
		reg = < 0x0 >;
		writeoc = "pp4io";
		readoc = "read4io";
		sck-frequency = < 0x7a1200 >;
		label = "MA25R64"; //   GD25LQ32E
		jedec-id = [ C2 28 17 ];
		sfdp-bfp = [ E5 20 F1 FF FF FF FF 03 44 EB 08 6B 08 3B 04 BB EE FF FF FF FF FF 00 FF FF FF 00 FF 0C 20 0F 52 10 D8 00 FF 23 72 F5 00 82 ED 04 CC 44 83 68 44 30 B0 30 B0 F7 C4 D5 5C 00 BE 29 FF F0 D0 FF FF ];

	};
};

Can you take a look at this this case, which I think is somewhat similiar but with another qpsi flash device:
https://devzone.nordicsemi.com/f/nordic-q-a/85983/qspi-flash-sample-project-error/

The data in blue as specific for the flash device, so just keep them as-is.
