From 6dff07bea4bb17b2d8012a4b223d7cc4f512e670 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?H=C3=A5kon=20Amundsen?= Date: Wed, 3 Dec 2025 08:59:06 +0100 Subject: [PATCH] boards: nordic: nrf54h20dk: add mbox for event report MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit cpusec will raise an mbox signal when an event report is generated. This is done when a peripheral triggers an error event to cpusec that cannot be directly passed to cpuapp or cpurad. Define the mbox and enable the IRQ for the corresponding bell in the bellboard.
