Last updated: January 05, 2026
Upstream Status: In Progress
Devices supported: Agilex 5
Introduction¶
The SEU driver is meticulously crafted to fulfill a dual purpose within its operational framework. Its primary function lies in promptly detecting and reporting single event upsets errors to users. Additionally, this subsystem offers a streamlined mechanism for the deliberate insertion of errors.
