RE: How to use SMP Protocol Specification with nrf52840 to update nrf5340 ?

Hi Pierre-Yves,

[quote user=""]but for a nrf5340(here i use thingy:53) i don't know how tu upload the app_update, i have always an error that i didn't had with the nrf52840. [/quote]

What error are you getting?

[quote user=""]I think the probleme can be the mcubootloader configuration, but i don't succed in the use of an MCUBootloader without : the CONFIG_UPDATEABLE_IMAGE_NUMBER=2[/quote]

You should be able to get it to work without CONFIG_UPDATEABLE_IMAGE_NUMBER=2 as long as you are not trying to update both cores simultaneously.

[quote user=""]But for the thingy:53 i used the thingy53_nrf5340_cpuapp.conf from bootloader\mcuboot\boot\zephyr\boards[/quote]

Please try with the following for thingy53_nrf5340_cpuapp.conf instead:
