Illegal use of the EPSR,add uart to the 5340 audio

RE: Illegal use of the EPSR,add uart to the 5340 audio

Hello,

Sorry for the delayed response,

I have included the use of uart2 as you are using.

Below is the code which I included (please note that uart2, and cdc-acm are defined as in the previous overlay):

//line added globally
const struct device *myuart2 = DEVICE_DT_GET(DT_NODELABEL(uart2));

//variables defined within main
uint8_t myuart2buffer[8]; size_t myuart2buflen = 8; 

//using the uart2 rx-enable as per the query
uart_rx_enable(myuart2, myuart2buffer, myuart2buflen, 0);

I built and programmed the DK using following in the terminal:

python .\tools\buildprog\buildprog.py -c both -b debug -d gateway -p

And I could see the output on the putty terminal connected to the correct com port

(screen capture after resetting the DK)

BR,

Naeem

Hi,

I explain the problem in detail: When I enable uart2, the error will appear. If I don't enable it, cdc works normally.

Hi,
Sorry for taking so long to reply, I was busy with other work in the meantime.

Please check my question specifically, the error will only occur if the above uart initialization is performed.
I used the overlay you provided and still the result didn't change.

Hello,

There might be some conflicts in your overlay.

Based on your input, I have modified and incorporated the overlay and I can see successful execution.

Adding complete overlay for your reference

There are some confidential fields in config, you may need to set the question as private to send

Reskyllr, you did not send the prj.conf

Hello Reskyllr,

Is there any update at your end?

I did not get much time to look at it, and also audio stuff is bit newer to me, so I will come back to you on Monday.

BR, Naeem

I am using ncs2.4 and an audio dk modified by myself.devzone.nordicsemi.com/.../7140.nrf5340_5F00_audio_5F00_dk_5F00_nrf5340_5F00_cpuapp.overlay

Note that this is a custom development board.

Hello Reskyllr,

Thank you for contacting DevZone at NordicSemi.

It can be that there is conflict of pins or configurations.

Can you share your dts overlays and prj.config to look more?

Which SDK you are using?

As you are building for the nrf5340DK or the Audio DK?

Regards,

Naeem
