In the course theory, it also explains why this file is used

Which file did you add this to?

academy.nordicsemi.com/.../. I have a question to ask you here.

3. Add DFU over UART to MCUboot There is a problem from here.
CONFIG_MCUBOOT_SERIAL=y
CONFIG_BOOT_SERIAL_UART=y
CONFIG_SINGLE_APPLICATION_SLOT=y
They say this setting doesn't exist
I am using nrf connect sdk version 2.5.0
Do I need to change my version or are there any settings that have changed?

[quote user="Min Hyuk"]The reason for this is because the nRF52840dk board I use does not support UDP.

To use the ECM5200-UART module for the nRF52840, you will need a driver for this to run in your nRF52840 firmware.

Once you have that, I think/hope that you simply can configure the DFU to use UDP instead of UART with CONFIG_MCUMGR_TRANSPORT_UDP. But yes you first need to make sure that you are able to use the ethernet and UDP via the module.

PS: Serial recovery only supports UART and USB, and not UDP.

Thanks for your help!

I succeeded with UART after looking at the link you provided.
I have a question here
docs.zephyrproject.org/.../mcumgr.html
If you look here, there is also udp in transports.
The reason I say this is that the project I have to do now requires passing data through the udp to uart module.
The module I use is ECM5200-UART
I am using the UDP to UART module on my PC to send data via UDP and receive it via UART on the board to update the firmware.
The reason for this is because the nRF52840dk board I use does not support UDP.
Is there a way to update firmware via udp? and
Is it possible to update the firmware for this scenario I need to develop?

Hi,

Have a read at the Bootloader and DFU lesson at https://academy.nordicsemi.com/courses/nrf-connect-sdk-intermediate/.

Then let me know if your questions are still the same
