Took long time to reset device after dfu through bt smp

[Llama12580]

I run a matter light_switch demo on my nrf54l15dk board, and I added these two configurations in prj.conf to enable dfu over bt smp. Built and burned the firmware into my board.

 

CONFIG_CHIP_DFU_OVER_BT_SMP=y
CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU=y

Then I used nRF Connect App to connect to my board, uploaded dfu_application.zip built when building firmware, and started dfu.

Everything was ok, but it took a long time(about 3 minutes) to reset device after the dfu progress reached 100%. I think it was switching firmware slot or doing something else.

Was that normal? Or are there any way to make it reset quickly?

Hello,

Which version of SDK you are using? I am using v2.8.0.

We have some updates in terms of writing in the flash of nRF54L15.  So, if you use previous version of SDK, you may see the increase swap.
