gicDemo

This is a small embedded application skeleton for demonstrating how to configure GIC v3 for interrupt handling on ARMv8A systems. This demo application is incrementally built on top of aohzju/embAppStartup. It's built and tested on ARM virtual platform ARMv8A AEM model: FVP_Base_RevC-2xAEMv8A.

Build and run

the armclang toolchain is used to build this example. And the build script is CMake script. It's tested on ARM FVP FVP_Base_RevC-2xAEMv8A. Assuming your development environment is correctly set up, this is the steps to build:

1. Creae a build directory: mkdir build
2. CD to build: cd build.
3. cmake ../
4. cmake --build . -v

Hopefully, you'll get appGicDemo.axf up to this point.

To run the demo:

FVP_Base_RevC-2xAEMv8A -C bp.secure_memory=false -C bp.terminal_0.mode=raw -C bp.refcounter.non_arch_start_at_default=1 -C cluster0.gicv3.FIQEn-RAO=1 -a appGicDemo.axf

ARM FVP

The virtual platform used in this application is FVP_Base_RevC-2xAEMv8A, which can be downloaded here.
