Trusted Firmware-A (TF-A) is a reference implementation of secure world software (EL3 firmware, trusted boot, and a small trusted runtime) for Armv7-A, Armv8-A, and Armv9-A application processors. This repository is a read-only GitHub mirror of the official TrustedFirmware.org project, written in C.
Use cases
- implement secure boot for an Arm SoC
- port EL3 secure monitor firmware to a new Arm platform
- build a Trusted Execution Environment foundation with TrustZone
- bring up a custom Armv8-A board with reference firmware
- comply with Arm security specifications for chip designs
When to choose
- you are developing or porting firmware for Arm A-Profile processors
- you need a standards-compliant trusted boot and EL3 runtime
- you want the reference implementation of Arm security specifications
When to avoid
- you need firmware for Cortex-M microcontrollers (use Trusted Firmware-M instead)
- you are looking for a general-purpose bootloader like U-Boot
- you need application-level software rather than low-level secure firmware
