How to implement DFU for blinky sample code with LED status logs for nRF54L15

I have an nRF54L15 dk board upon which I want to implement DFU, I have followed all the steps until "4. Build and flash the application to your board." where I could build and flash to the board. I understand that the UART console is disabled, and I wont be able to see any logs. But the LED is not blinking and I am not able to DFU using auterm.

Could anyone guide me on how to implement DFU for this board using serial recovery and also be able to print logs perhaps on a different UART channel.



I am attaching my project file for your reference.Blinky5.zip

Hi did you include this config from the instructions in step 3.1? Add "

CONFIG_PM_PARTITION_SIZE_MCUBOOT=0xF000

" in your mcuboot.conf


If you also want logging and serial recovery, you need to add an overlay to change the default uart console to a different uart. This is because on nrf54l15, both mcu-mgr and console are on &uart20

Hi DanielNG thank you for a quick response. There is still no difference, the LED0 does not blink even after adding"

CONFIG_PM_PARTITION_SIZE_MCUBOOT=0xF000"
