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.
|
|
|
|
