EVMK2H: difference between Linux/Linux-RT/RTOS Processor SDK

Hi every one,

For SDK there are three software:

1-Linux Processor SDK for K2H

2-Linux-RT Processor SDK for K2H

3- RTOS Processor SDK for K2H

I read a lot but I really confused. the difference between these three software is just the operating system of the host computer?

I mean if I choose "Linux Processor SDK for K2H" is it consist of ARM and DSP of the board.

please help me on understanding it.

Regards

Matin

    Hi Matin,

    Those are 3 different operating systems for the K2H EVM.
    1-Linux Processor SDK for K2H --> This is a linux OS, Yocto distribution
    2-Linux-RT Processor SDK for K2H --> This is again Yocto distribution, but the kernel has the CONFIG_PREEMPT_RT patch integrated. This means that the kernel supports preemption & is capable of processing real time tasks, which have a defined time for execution, irq priority and so on, meaning that the maximum time of execution of a certain task can be calculated or measured reliably for the given application and environment.. You can learn more about the RT linux here:
    rt.wiki.kernel.org/.../Frequently_Asked_Questions
    3- RTOS Processor SDK for K2H --> This is a Real Time Operating System developed by TI for the K2H devices.

    Best Regards,
    Yordan
