Is there a way to work with FreeRTOS without hardware?

Guys, is there a way to work with FreeRTOS without hardware, like simulation, for example, on Keil or another platform?"

Is there a tool that can help me automate the process of identifying all QNX-related system calls?

@Middleware & OS , I'm working on migrating a legacy application from QNX Neutrino to an open-source Linux-based RTOS. I've identified the third-party libraries and device drivers requiring porting. However, the challenge is analyzing the codebase for dependencies on specific QNX features like MsgSend, MsgReply, and MsgSendPulse. Since the code was written by another team, I have limited knowledge beyond compilation and execution details. Is there a tool available that can help me automate the process of identifying all QNX-related system calls or functions used in the code?...

Why is there a need for a separate task stack in an RTOS?

So guys we know that In an RTOS (Real-Time Operating System), the Task Control Block (TCB) holds information for task management. But doesn't the TCB already include all the data needed for context switching, like register values? Why is there a separate task stack then? @Middleware & OS...

Memory Operations During Context Switch: Impact on Priority Tasks?

Hi @Middleware & OS I have two tasks, A and B, with A being high priority and B low priority. There are two global variables, condition and mem. Let's say Task B is currently running and performing memory operations. If Task A becomes ready while Task B is running, resulting in a context switch, will the memory operation continue even if the condition is set to false? If so, at which index will it restart? And what will the content of mem be after Task B finishes executing? ``` Task B - Low priority task
if (condition) { ........

When do we use polling method and when do we use interrupts based method in RTOS?

Hey guys so when it comes to managing tasks in real-time operating systems (RTOS), I studied from an article that polling is like constantly asking, 'Are we there yet?' and Interrupts, however, are like someone tapping you on the shoulder to say, 'We've arrived!' when driving a car, Lol. But, when do we use polling method and when do we use interrupts based method. Can you think of times when you might want to do both at once? @Middleware & OS @Priyanka Singh @Rémi @Navadeep @Umesh Lokhande @Computing Lead @FW Lead...

Hi guys !! I'm confused about the difference between cooperative and non-preemptive scheduling. Some sources say they're the same, while others mention that in non-preemptive scheduling, higher priority tasks can interrupt lower priority tasks only at system ticks. Can anyone clarify this?
