FreeRTOS is designed to be small and simple. The kernel itself consists of only three or four C files. To make the code readable, easy to port, and maintainable, it is written mostly in C, but there are a few assembly functions included where needed (mostly in architecture-specific scheduler routines).

Linux support

The mainline Linux kernel gained support for OpenRISC in version 3.1.[17] The implementation merged in this release is the 32-bit OpenRISC 1000 family (or1k).[18] Previously OpenRISC 1000 architecture, but this has now been superseded by the mainline port.


RTOS support

A number of real-time operating systems have been ported to OpenRISC, including RTEMS, FreeRTOS and eCos.


QEMU support

Since version 1.2 [19] QEMU supports emulating OpenRISC platforms.
