Dual-core support
Some of the STM32H7 chips have an additional Cortex-M4 core built-in. The selection of the core for which the image is build is made using options:
CONFIG_ARCH_CHIP_STM32H7_CORTEXM7- selects Cortex-M7 core
CONFIG_ARCH_CHIP_STM32H7_CORTEXM4- selects Cortex-M4 core
Support for the CM7 core is always enabled, support for the CM4 core is controlled
with the CONFIG_STM32H7_CORTEXM4_ENABLED option.
Interprocessor communication between cores is realized with the NuttX RPTUN
device based on the OpenAMP framework. HSEM is used for synchronization and
notification between cores.
32kB of the SRAM3 is reserved for shared memory and this is the only available option at the moment.
