Known limitations (carried into Rev B planning)

The nRF54L15 datasheet review (May 2026) identified silicon constraints affecting this revision:

  • UART0 debug (P0.02 TX / P2.07 RX) is split across P0/P2 — non-functional. TX-only debug possible.
  • Battery inputs on P2DC_PRESENT (P2.03), CHARGE_STATUS (P2.04) — must be polled.
  • Service button (P2.06) must be polled.
  • Sensor INT on P2.09 (was ACC.INT2 on 230220) — must be polled. Compatible with Acconeer A121 (host-driven SPI polling, no INT required) but blocks any sensor that needs edge-triggered host wakeup.

Sensor SPI candidate pins (P1.11/P1.13/P1.14/P1.08) are all on port P1, so SPIM22 (P1-only) can bind them — the sensor SPI itself is functional on this revision. Addressed in the planned Rev B1 GPIO remap. See Firmware Compatibility for full impact analysis.
