Sorry, I meant spm.c, as linked in the reply I shared:

There is no spim.c file in the project.

But are you sure that you have added the following to spim.c?

#ifdef NRF_I2S
		PERIPH("NRF_I2S", NRF_I2S, 1),
#endif

This code is required to ensure that the I2S is accessible in the non-secure application, else it will only be accessible in the secure domain.

Btw, you are using a very old NCS release, the latest is v1.5. I recommend to update if possible.

Hi Kenneth,

I have looked that case. The condition is different. I don't use the Zephyr file, I am using the code in the user manual.

I have also tried the code in the Zephyr I2S api, it doesn't work. I use ncs 1.2.0 and the path of i2s is ncs\zephyr\tests\drivers\i2s. There are two projects i2s_api and i2s_speed. I can run the i2s_speed but the i2s_api doesn't work rightly. It always has error in this part.

Hello,

Try to take a look at this case: https://devzone.nordicsemi.com/f/nordic-q-a/60256/i2s-on-nrf9160/245191#245191

I suspect it's related to either of those comments.
