Hi,

There are some examples for nRF9160 DK, for example in LwM2M client sample and HTTP full modem update sample:

&spi3 {
	compatible = "nordic,nrf-spim";
	status = "okay";
	sck-pin = <13>;
	mosi-pin = <11>;
	miso-pin = <12>;
	cs-gpios = <&gpio0 25 GPIO_ACTIVE_LOW>;
	mx25r64: mx25r6435f@0 {
		compatible = "jedec,spi-nor";
		reg = <0>;
		spi-max-frequency = <80000000>;
		label = "MX25R64";
		jedec-id = [c2 28 17];
		size = <67108864>;
	};
};

This is from nrf/samples/nrf9160/lwm2m_client/boards/nrf9160dk_nrf9160_ns.overlay, and you will find something similar in nrf/samples/nrf9160/http_update/full_modem_update/boards/nrf9160dk_nrf9160_ns.overlay.

Best regards,

Marte

Hi Marte,

Is there a .dts example for external SPI flash?

Just like this:

&qspi {
	status = "okay";
	sck-pin = <19>;
	io-pins = <20>, <21>, <22>, <23>;
	csn-pins = <17>;
	mx25r64: mx25r6435f@0 {
		compatible = "nordic,qspi-nor";
		reg = <0>;
		/* MX25R64 supports only pp and pp4io */
		writeoc = "pp4io";
		/* MX25R64 supports all readoc options */
		readoc = "read4io";
		sck-frequency = <8000000>;
		label = "MX25R64";
		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 = <67108864>;
		has-dpd;
		t-enter-dpd = <10000>;
		t-exit-dpd = <35000>;
	};
};

Hi,

Yes, you can also use external SPI flash.

Best regards,

Marte

In addition, I see that the example uses QSPI External Flash, can I replace it with SPI External Flash?

Hi Marte,

Thanks for your reply.

I will try to add external flash to smp_svr and see if it works.

Thanks again.

Hi,

This seems to be a bug in SES setting a path incorrectly, causing CMake to fail when generating for MCUboot. Please try building with VS Code or on command line instead.

Please be aware that the example you are linking to has not been tested in nRF Connect SDK v1.9.1, only v1.8.1 and earlier, and that this is not an official example.

For DFU you can also use the SMP Server Sample. This does not use external flash, but you can add it yourself by following Partition Manager » External flash memory partitions and Using external flash memory partitions.

Best regards,

Marte
