Hi,

I am planning to learn FreeRTOS internal for a course project.I would like to know where to start with if i want to edit the scheduler and try implementing EDF algorithm in the scheduler.

Thanks in advance!

All the FreeRTOS documentation really deals with how to use FreeRTOS, and general multitasking programming concepts, not how it works - although all the source code is available and is well documented in itself (plus its quite small). This might be the closest to, but not actually, what you are looking for: www.freertos.org/implementation

Regards.
