Some non-Mbed-OS, pre-existing CMSIS-RTOSv2 applications depend on CMSIS-RTOSv2 Automatic Dynamic Allocation, also known as Object-specific memory pools. Mbed OS doesn't by default provide any memory to the CMSIS-RTOSv2 Automatic Dynamic Allocation pool, as doing so would waste memory if the feature is not used; even if the feature is used, as a platform, Mbed OS can't know how many objects of which types will be created by an application and therefore will either waste memory or not provide enough memory in a hard to debug manner. Portable CMSIS-RTOSv2 applications depending on CMSIS-RTOSv2 Automatic Dynamic Allocation should instead configure the memory pools themselves, as applications know best their memory requirements. Add Mbed configuration options which can be used by applications to control the amounts of memory available to the CMSIS-RTOSv2 Automatic Dynamic Allocation subsystem. This enables portable CMSIS-RTOSv2 applications, which can run on any CMSIS-RTOSv2 OS, to be able to run on Mbed OS as well. RTX's configuration options for CMSIS-RTOSv2 memory are documented at http://www.keil.com/pack/doc/CMSIS_Dev/RTOS2/html/config_rtx5.html Signed-off-by: Devaraj Ranganna <devaraj.ranganna@arm.com> Signed-off-by: Jaeden Amero <jaeden.amero@arm.com> |

README.md
Arm Mbed OS is an open source embedded operating system designed specifically for the "things" in the Internet of Things. It includes all the features you need to develop a connected product based on an Arm Cortex-M microcontroller, including security, connectivity, an RTOS and drivers for sensors and I/O devices.
Mbed OS provides a platform that includes:
- Security foundations.
- Cloud management services.
- Drivers for sensors, I/O devices and connectivity.
