- Corstone1000 Platform
- ==========================
- Some of the features of the Corstone1000 platform referenced in TF-A include:
- - Cortex-A35 application processor (64-bit mode)
- - Secure Enclave
- - GIC-400
- - Trusted Board Boot
- Boot Sequence
- -------------
- The board boot relies on CoT (chain of trust). The trusted-firmware-a
- BL2 is extracted from the FIP and verified by the Secure Enclave
- processor. BL2 verification relies on the signature area at the
- beginning of the BL2 image. This area is needed by the SecureEnclave
- bootloader.
- Then, the application processor is released from reset and starts by
- executing BL2.
- BL2 performs the actions described in the trusted-firmware-a TBB design
- document.
- Build Procedure (TF-A only)
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~
- - Obtain AArch64 ELF bare-metal target `toolchain <https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-a/downloads>`_.
- Set the CROSS_COMPILE environment variable to point to the toolchain folder.
- - Build TF-A:
- .. code:: shell
