Hi,
We are using both nRF54L15 and nRF54L10 in our product, with DFU support where an external flash is used as the secondary partition on both MCUs. The hardware connections are identical on both boards.
To define partitions, we use partition manager with a pm_static.yml file (attached), which is the same for both MCUs and allocates around 850–900 KB of internal flash.
Question:
From our understanding, the only difference between nRF54L15 and nRF54L10 is the available flash and RAM, while the rest of the hardware is the same.
Our project is built using the nRF54L10 configuration to account for memory limitations.

Board target:
nrf54l15dk/nrf54l10/cpuapp -
Base overlay: our custom board overlay
hence we are using partition manager so its overtight other partition right?
Can we run the same nRF54L10 build on the nRF54L15 board?
