We are planning to move our flagship product to ARM platform along with RealView RTX kernel RTOS. We have used UCOS2 RTOS for years and it has proved itself to be a very robust operating system. I would like to have expert comments on features and robustness of RealView RTX Kernel RTOS in comparison with UCOS2 RTOS robustness in preemptive multitasking environment on ARM processor.
One I thing could not do in RTX was suspend a task from another task, this can be easily done in uC/OS-II.
I had to result to terminating and then restarting the task, which was far from ideal in the particular circumstances.
I am not sure if this could have been done some other way? Any ideas?
Drop the thread priority very low and have a running dummy thread with higher priority making sure that the thread stays inactive?
Per that is a good idea. I would still prefer it as a feature though as I do loath to have an extra task acting as an effective second idle task.
I am going to try something dangerous as an experiment (not that I would use it in my real system!). If it is possible I am going to try and raise the idle task priority to 2 and then move other tasks to 1... and see the havoc this creates!
