Hi yama-san,

Thank you for verifying. I've started looking into recreating what you're seeing on the nrf5340, but I still have some items I need to verify before I can give you an answer. For now, could you verify if the new firmware you're trying to upload is from the same build, or a new build with some modification (a print or a version change)? If you have one available, do you see the same thing when using a nRF5340DK? No worries if you don't have one. I will be recreating the exercise with a DK.

Kind regards,
Andreas

Hi, andreas-san

Yes, I have checked and learned about it.
I also have checkd thsi page MCUboot’s serial recovery of the networking core image
my configuration is based on this page.

However, simultaneous updates are not possible.

Hi,

I will look into this closer, but I will need some time to set it up myself to better understand serial dfu over USB. In the meanwhile, could you state if you've gone through this exercise and compared it to your solution? https://academy.nordicsemi.com/courses/nrf-connect-sdk-intermediate/lessons/lesson-8-bootloaders-and-dfu-fota/topic/exercise-2-dfu-over-usb-adding-external-flash/

Kind regards,
Andreas
