nordic_nrf7002dk reserves 32 KB for storage_partition. Nothing reads it: the port's only settings user is common-hal/_bleio/Adapter.c:351, and this board sets CONFIG_BT=n. CIRCUITPY is on the external mx25r64 on spi4, not internal flash. 0xC000 + 0xF4000 = 0x100000, exactly the end of the nRF5340 application core's 1024 KB internal flash. Not built. I don't have a nRF7002 to verify with. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

The ja translation overflows FLASH by 176 bytes on this board with the MicroPython v1.28.0 update. The board is at 99.99% on main, with 80 bytes free in that translation, so a routine upstream release does not fit. The other 12 translations build. The three new upstream modules are not the cause. On a board build py/modstring.c, py/modweakref.c and py/objtemplate.c all have zero .text, no symbols in the ELF and none of their error strings in the binary, because their feature gates sit above CircuitPython's ROM level. The growth is ordinary expansion across py/. msgpack is chosen because it is self contained and has no tie to any peripheral on this board, so nothing else loses a capability. This is temporary. adafruit#11335 gives slot0 the unused 32 KB storage partition, which is 186 times the shortfall, and this gate should be reverted when that lands.

What
nordic_nrf7002dkreserves 32 KB forstorage_partition. Nothing reads it: the onlysettings user is
_bleio, and this board setsCONFIG_BT=n.0x0C000 + 0x0F4000 = 0x100000, end of flash. CIRCUITPY is on the external mx25r64 on spi4.
Why
This board is the port's flash ceiling. shared-bindings additions overflow it and get
gated per board, most recently in #11309.
Testing
Not built. I don't have a nRF7002 to verify with. Opening it so someone with the board can check.
AI assistance: Claude read the devicetree and git history and drafted the change. I have
not built or run it.
