Hi,
Should we use NCS 3.2.4 or 3.3.0 for Matter protocol ?
The NCS page says to use 3.3.0 https://wiki.seeedstudio.com/xiao_nrf54lm20a_ncs/#install-nrf-connect-sdk-and-toolchain
Build is failing because the usable internal flash for flash_primary is 1940 KB (0x1E5000 bytes) — confirmed by the CMake invocation (–flash_primary-size;0x1e5000) and the reported region size (1986560 B).
However, pm_static_xiao_nrf54lm20a_nrf54lm20a_cpuapp.yml statically laid out:
Partition Size
mcuboot 0xD000
mcuboot_pad 0x800
app 0x1E2800
factory_data 0x1000
settings_storage 0xC000
Total 0x1FD000
That’s 0x18000 (96 KB) more than the 0x1E5000 actually available. Partition Manager can’t reconcile a static layout that overflows the region, and reports it as two nonsensical “gaps” instead of a clear size-overflow error.
