RTOS result

There are few results that had been obtained to testing the performance of the RTOS. Compare the relationship between instruction cycle used for initialization with different optimization level in different type of RTOS For...

Context switching in FreeRTOS

FreeRTOS capable to run multiple tasks by using tasks switching method. Scheduler is the kernel who doing the task switching operation. The scheduler will changing the task into running state when it is require....

TCB in FreeRTOS

Last week, I found that the value pxCurrentTCB is different from the instruction address of my task created. After discuss with Dr Shawn, he told me that the value of pxCurrentTCB should be different from...

Stack pointer in FreeRTOS

This week I am trying to implement the stack initialization to the system. Other than that, the FreeRTOS required programmer to make functions to save and restore context of the system during tasks switching....

Starting FreeRTOS

This week I trying to port another RTOS to our microprocessor. The purpose to learn this OS because it usually run preemptive operation in event scheduler. Same as Contiki, FreeRTOS also a RTOS design for small and...

Contiki and FreeRTOS

Last week, I am still doing on contiki’s functions testing in my new porting microprocessor and platform. After 1 week plus of function testing, the basic functions are working in my porting microprocessor and...

Running Tasks with Contiki

In contiki os, there are a lot of functions predefined in the core file. During programming in contiki os, programmers require to follow the contiki programming style to create their own code. These functions are PROCESS_BEGIN(), PROCESS_END(), PROCESS_YIELD()...

Compilation Dummy Contiki

This week I am working on dummy contiki OS to be compile using RISC V compiler. During compilation, there are a lot errors prone. Most of the errors happened during typo occur in the code,...

Working on Contiki OS

This week I having more explore on Contiki OS. Dr. Shawn explained on our processor architecture which gave me clearer picture what I need to do my project. Besides that, he also explained on the concept...

First week of internship

This is the first week internship in Aeste Work (M) Sdn. Bhd.. The first day, Dr Shawn introduced the project background to us and I will work on the operating system of the project....
