FreeRTOS Preemptive Kernel

This post presents the sixth and the last phase of porting FreeRTOS for AEMB processor. In the previous post, both interrupt and interrupt handling were implemented to serve the mechanism of the preemptive kernel. Although, things seemed fine and set, yet the kernel failed to work when FreeRTOS tasks were Read more…

FreeRTOS Tick and Tick Handling

This post represents the fifth phase of porting FreeRTOS for AEMB processor. The main concern of this phase is to get the FreeRTOS configured to demonstrate the Preemptive Multitasking. By far this phase deals with the following: Setting up the timer to generate the RTOS Tick Handling the RTOS Tick Read more…

FreeRTOS Cooperative Kernel

In the previous post, I wrote about creating a simple FreeRTOS task. However, to demonstrate the FreeRTOS cooperative kernel, more than one task is needed. Basically when starting the FreeRTOS scheduler, an Idle task is automatically created which is an infinite loop so when the kernel starts running, it will Read more…

Running a FreeRTOS Task

Continuing the series of the posts about my work in porting FreeRTOS for AEMB processor, this represents the third phase of the project which is running a simple FreeRTOS task. In my previous post I mentioned about a problem that I faced during simulating FreeRTOS by using Icarus Verilog. While Read more…

Simulating FreeRTOS

In this post, I will explain to you how the simulation of the FreeRTOS kernel was accomplished for AEMB processor. The second phase of porting FreeRTOS for AEMB according to the project plan is simulating the compiled and linked FreeRTOS kernel on top of AEMB hardware. As I mentioned in Read more…

Compiling FreeRTOS

As promised, I am back to continue my series of posts on working on a FreeRTOS port for the AEMB core. Yet before I go in any further, let me give a short introduction about FreeRTOS and walk you through my overall plan for getting my project done before I Read more…
