The next target in line +would be the PIC32, on its development board form. + +The main goal is to get the cleanest architecture as possible, providing +the same, clean API to all the supported CPUs. + + +Architecture / Layout +--------------------- + +RTOS: + +The FreeRTOS directory contains the FreeRTOS source code. The main +modification done there is a few minor bug fixes, and adding the support +to the _impure_ptr switching support for newlib's reent system. The current +memory management is done using newlib's allocator. + +Architectures: + +The arch directory contains architecture-specific code, including assembly +code, drivers and link scripts. + +System: + +The os directory contains more generic code, in order to boot the CPU, set up +your binary's environment, provide the necessary glue to newlib, and set up +a proper shutdown sequence. + + +ARM / Cortex-M3 / mbed +---------------------- + +The arch directory contains NXP's port of CMSIS for their LPX1768 CPU. Using +their drivers is highly recommended. |
