AMD Platform Security Processor (PSP) error

What is AMD-PSP-ERROR?

AMD Platform Security Processor (PSP) error is a high-severity processor (CPU) issue. 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. This can also stem from incompatible AGESA version. The steps below are ordered to resolve this efficiently.

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

  "Disable fTPM temporarily to isolate issue" is worth trying when corrupted fTPM data turns out to be the culprit.
