Phoenix-RTOS is based on the written from scratch dedicated microkernel. Microkernel is effectively implemented and consists of about 20K lines of code (LoC). Microkernel is responsible for:
- memory management,
- thread and process management,
- inter-thread communication and synchronization.
Kernel is divided into five subsystems.
- hal - hardware abstraction layer
- lib - common routines
- vm - virtual memory management
- proc - process and thread management
- test - test for other subsystems
Kernel source code
The source code of the kernel could be obtained using the following command
git clone http://github.com/phoenix-rtos.com/phoenix-rtos-kernel
For compilation of the microkernel traditional make system is used. To compile you should define the
TARGET variable in the main
Makefile located in
src/ directory. The list of available targets is defined inside the file. The structure of target consist of three parts:
After defining the
TARGET variable the set of command should be used.
Removes all intermediate files (e.g. object files).
Analyses dependencies between files and stores it in
Compiles kernel and creates the ELF and BIN files in
