AMD Platform Security Processor (PSP) error

What is AMD-PSP-ERROR?

The AMD Platform Security Processor (PSP) is an ARM Cortex-A5 security coprocessor embedded in AMD CPUs and APUs. A PSP error typically manifests as a boot failure with debug LED codes or BIOS error messages. PSP handles secure boot validation, fTPM operations, and AMD Memory Guard encryption. Errors here block system initialization.

Common Causes

• Corrupted fTPM data
• BIOS update interrupted PSP firmware
• Incompatible AGESA version

Step-by-Step Fix Guide

• 1
  Clear fTPM data in BIOS (AMD fTPM Reset)

  Resetting fTPM in BIOS settings resolves most PSP errors caused by corrupted security state data.

• 2
  Update BIOS to latest AGESA version

  A BIOS update with updated AGESA is the long-term fix.

• 3
  Disable fTPM temporarily to isolate issue
