Hi Man0, sorry for the late reply.

Your project share some similarities but it will be easier to debug if you create a new case:) Please link to this case if relevant and explain which parts are similar. I will be happy to take your case.

Best regards,

Håkon

Hi Nicolas,

I'm experiencing the same problem with Zephyr 2.6.99, nrf Connect SDK 1.7.
Any update one this ?

I have too Maxim Flash on same the SPI bus:

&spi4 {
	compatible = "nordic,nrf-spim";
	status = "okay";
	sck-pin = <7>;
	mosi-pin = <12>;
	miso-pin = <27>;
	cs-gpios = <&gpio1 7 GPIO_ACTIVE_LOW>,
				 <&gpio1 5 GPIO_ACTIVE_LOW>;

	mx25U16_0: mx25u1633@0 {
		compatible = "jedec,spi-nor";
		status = "okay";
		reg = <0>;
		spi-max-frequency = <600000>;
		label = "MX25U16_0";
		jedec-id = [c2 25 35];
		size = <16777216>;
	};

	mx25U16_1: mx25u1633@1 {
		compatible = "jedec,spi-nor";
		status = "okay";
		reg = <1>;
		spi-max-frequency = <600000>;
		label = "MX25U16_1";
		jedec-id = [c2 25 35];
		size = <16777216>;
	};
}

Hi Nicolas,

Thank you for your request.

Which nRF Connect SDK version are you working with?
