Hi,

I have not seen these unavailable audio ports when I flashed your application to the board.

Hi,

You should be able to see the image in the slot by using the following command:

mcumgr -c <your_connection_name> image list

Hi,

Please see the attachment. It combines two sample(smp_svr + headphones_microphone).

I want to use USB DFU + USB Audio.

These steps are normal DFU steps, using mcumgr .

Hi,

Excuse me.

I added CONFIG_USB_NRFX_EVT_QUEUE_SIZE, this time with no error, it compiled successfully.

I checked autoconf.h to confirm that the configuration was successful.

But does not resolve usb error:(<err> usb_nrfx: USBD event allocation failed!).the same as before.

When I tried to upload the error was as follows:

Cloud you tell me how to solve this problem?

thanks.

Hi,

Could you show what happened when you added CONFIG_USB_NRFX_EVT_QUEUE_SIZE? What are the dependencies that you are having issues with? Do you get any build error? Is this error different than before? Can you show the error?

Best regards,
Dejan

Hi,

I tried. but CONFIG_USB_NRFX_EVT_QUEUE_SIZE requires a series of dependencies, some of which I cannot configure successfully.

Could you please give me a completed configuration.

thanks.

Hi,

You could try increasing the value for Kconfig option CONFIG_USB_NRFX_EVT_QUEUE_SIZE.

The test board is nRF5340-DK.

build command:

west build -b nrf5340dk_nrf5340_cpuapp -- -DOVERLAY_CONFIG=overlay-cdc.conf -DDTC_OVERLAY_FILE=usb.overlay

NCS v2.1.0\zephyr\samples\subsys\mgmt\mcumgr\smp_svr

Test the original project, USB DFU is OK.

mcumgr.exe conn add myCOM type="serial" connstring="dev=COM5,baud=115200,mtu=256"

mcumgr.exe -c myCOM image upload .\app_update.bin

Add NCS v2.1.0\zephyr\samples\subsys\usb\audio\headphones_microphone to the smp_svr project(the attachments you can find it), it get error when use commod to upload the bin file
