RAM
The requirements of the Operating System depends heavily on the configuration. It is scalable from small microcontrollers with 20 KiB of RAM to larger microcontrollers with 192 KiB or even megabytes. For the full configuration, a microcontroller with 128 KiB or more RAM is recommended.
Flash
The necessary amount of flash required varies with the enabled features. A small feature set will make it fit within a few kilobytes, while a fully featured build is in the order of 80 KB.
CPU
The following CPU architectures are currently supported:
- ARM Cortex-M3
- ARM Cortex-M4
- ARM Cortex-M7 (but not cache-enabled yet)
- ARM Cortex-R4
Microcontrollers and Drivers
Basic hardware drivers are written for the ST STM32 line of microcontrollers, some are also written for the Texas Instruments TMS570LS1224 microcontroller.
