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
|
2023-09-16 15:25:30 +02:00
|
|
|
option at the moment.
