Hi Dileep,

Yes it should be possible to perform DFU via the nRF USB. You can also take a look at this DFU USB examples developed by one of my colleague: https://github.com/hellesvik-nordic/samples_for_nrf_connect_sdk/tree/main/bootloader_samples/serial_recovery/mcuboot_serial_recovery_cdc_acm

Thank you for reply,i connected two usb cables from PC to DK board. one usb cable to short side of DK and other to long side side of DK(nrf USB). SOC is mainly connected to nrf usb and Debugger connected to usb side on short side of DK board. can i do any modifications or configurations such that DFU will be updated through nRF USB connector.

Hi Dileep,

You can perform DFU using the nRF USB port, but then you also need to power the DK at the other USB port too (the one on the short side).

Best Regards,
