Hi,

Could you describe your setup?

Which board do you use?

Did you follow the configuring FOTA upgrades guide?

Best regards,
Dejan

Hi 

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

Hi,

You could try increasing the value for Kconfig option CONFIG_USB_NRFX_EVT_QUEUE_SIZE.

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,

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

[charles.jiazhen]

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,
