FreeRTOS v10.3.1 on ARM fixed virtual platform FVP_Base_RevC-2xAEMv8

FreeRTOS port for ARM FVP (Fixed Virtual Platform) AEM_Arvm8-A: FVP_Base_RevC-2xAEMv8. The virtual platform is an Armv8-A model with GIC (Generic Interrupt Controller) supported. This porting supports single core only.

This port can be adapted for any Armv8-A platform.

Differences from the port GCC\ARM_CA53_64_BIT:

• A virtual platform is used for demonstration
• The maximum number of unique task priorities is changed from 32 to 64 (Armv8-A aarch64 platform)
• System registers are used for GIC CPU interfaces.
• More concise assembly code
• CMake scripts used for building. The armclang compiler is used.
• Removed interrupt nesting support
