Hello,
I am developing a custom PCB for use with the nRF5340 and would like to change the default pin values of the I2S module on my nRF5340 Audio DK first in order to validate. I would like to start by moving BCLK to P0.19.
Can you please help me understand how to do so?
Thank you!
Best,
Louie
Hello
Zephyr uses a devicetree structure to keep track of hardware and peripherals. When building, a devicetree is generated based on different files in the SDK, this devicetree ends up in build/zephyr/zephyr.dts. I would recommend having a look at this devicetree file to get an idea what it looks like.
In order to make changes to nodes in this devicetree you should make an overlay file and include it in your project. You can read about how to do that here:
In your case you'll want to make changes to the i2s part of the pinctrl node to change which pins are used.
I would also recommend going through our NCS fundamentals course if you're new to working with NCS/Zephyr:
https://academy.nordicsemi.com/courses/nrf-connect-sdk-fundamentals/
Best regards,
Einar
Hi Einar,
Thanks for the support.
I've tried a number of things with your recommendations and I am not having any luck. I'm wondering if you could potentially point me in the right direction.
I created the following overlay file (nrf5340_audio_dk_nrf5340.overlay) at this path (C:\ncs\v2.2.0\nrf\applications\nrf5340_audio-external_hw_codec):
&i2s0_default {
group1 {
psels = <NRF_PSEL(NRF_FUN_I2S_SCK_M, 1, 12)>;
};
};which yielded the following errors:

I created these various attempts at overlay files using the information found at the following links:
How to use Zephyr Pin Control (pinctrl) for pin multiplexing and configuration
However, I am unsure of what the proper format of my overlay file should be, especially since the zephyr.dts file's i2s code apparently has a different syntax than the above links'.
I also added the following snippet of code to my CMakeLists.txt file per the recommendation of this link
#
# Copyright (c) 2022 Nordic Semiconductor ASA
#
# SPDX-License-Identifier: LicenseRef-Nordic-5-Clause
#
set(DTC_OVERLAY_FILE "${CMAKE_CURRENT_SOURCE_DIR}/nrf5340_audio_dk_nrf5340.overlay")
cmake_minimum_required(VERSION 3.20.0)
# ... Rest of the CMakeLists.txt contents
Again, all I am trying to do is change the BCLK (or SCK as it is referred to in code) output to P1.12 (or any other unused pin) on my nRF5340 Audio Dev kit.
Thank you!
Best,
Louie
Hi
Could you share what your generated zephyr.dts looks like when you use the first of those overlays?
I suspect it might be supposed to look like this:
&pinctrl {
i2s0_default {
group1 {
psels = <NRF_PSEL(NRF_FUN_I2S_SCK_M, 1, 12)>;
};
};
};
Though I'm not entirely sure if the way you're doing it shouldn't also work, but you can always check if the devicetree was generated the way you expected with these types of errors.

Hi Einar,
Thanks for the response!
When I use the following overlay
&i2s0_default {

Any suggestions for what else I could try?
Thanks so much!

Hm I see, well looking at your generated devicetree it seems that you're simply not able to make changes to it because of this parse error.
Looking at your error message; expected number or parenthesized expression, are you sure that NRF_FUN_I2S_SCK_M is defined properly?
I cannot spot anything else in your little overlay that I would expect to cause such an error.
