Yes.

In such cases, the newly generated application images may no longer use a partition map that is compatible with the partition map used by the bootloader. As a result, the newly built application image may not be bootable by the bootloader.

Hi Amanda,

We are using pm_static.yml to define the partitions. Is that what you mean? In the new firmware the layout was changed as mcuboot partition was reduced in size. Which is the focus of my question, if that is possible or not.

Hi,

Do you use the same static partitioning for old/new firmware? See Static partition requirement for DFU
