Hi,

The changes in device tree can be added to your boards/<board>.overlay, which is nrf7002dk_nrf5340_cpuapp.overlay if you use the nRF7002-DK board.

The build folder is generated when you select your project and configure (ie. select the board to compile for etc) - if you just create a new build, the above mentioned overlay should be selected.

Kind regards,

Håkon

Thank your for your reply Håkon.

That is the exact location where i did described changes.

Can you describe which folder is to be deleted and how to regenerate it?

Kind regards,

Leon

Hi,

What did you change?

Here's a simplified overlay where you can alter the qspi-frequency:

&qspi {
	nrf70: nrf7002@1 {
		compatible = "nordic,nrf7002-qspi";
		status = "okay";
		qspi-frequency = <24000000>;

	};
};

Remember to delete your build folder and regenerate it after adding a .overlay.

Kind regards,

Håkon
