CCS/TMS320C6678: MCSDK, SYSBIOS and TI-RTOS

Part Number: TMS320C6678
Other Parts Discussed in Thread: SYSBIOS

Tool/software: Code Composer Studio

Hi everybody,

I have a few questions related to basically version and version compatibility of things specified in thread title.

1. It seems that SYSBIOS is replaced with TI-RTOS. Is TI-RTOS available for C6678. If available is there any version of MCSDK that includes this TI-RTOS.

2. If TI-RTOS is not available then only choice is SYSBIOS. Is there any version of MCSDK that includes the last SYSBIOS version and what? If not what is the last version of MCSDK and the version of SYSBIOS that included in. 

3. If last version of SYSBIOS is not included in MCSDK, is it possible to get last version MCSDK and put the last verison of SYSBIOS in it. If there is any special consideration for this case can you please specify them..

Thanks in advance

    Hi Zeki,

    We've not done the best job on branding. SYS/BIOS is the kernel we've had for many years. A few years ago when TI started offering Arm MCU devices, we decided to bundle the kernel with drivers and stacks (e.g. NDK...networking stack) and call it TI-RTOS. We wanted to call it TI-RTOS since it was truly an RTOS instead of a kernel. We waffled on what to call SYS/BIOS for C66 devices since internally the C66 team supplies the drivers and SDK, while the kernel team just supplied the kernel to the SDK. We decided to rebrand SYS/BIOS as TI-RTOS for C66 also but we left the name SYS/BIOS for things like directories, etc. for legacy reasons...

    To make it even more confusing we did have a TI-RTOS for Sitara release several years ago but only had one release. It was the kernel and NDK, but no drivers. I know...kinda of a mess.

    The MCSDK does ship SYS/BIOS and you can get a newer SYS/BIOS kernel here: software-dl.ti.com/.../index.html

    I would check with the MCSDK team to see if what versions of SYS/BIOS they recommend to use with the version of SDK you have though.

    Hi Todd,

    Thank you for quick response.

    ----------------------------------------------------------------

    Using Code Composer Studio 7.3.0.

    It seems that we will continue to use MCSDK and SYSBIOS for c6678.

    Could you please check the last compatible versions of MCSDK and SYSBIOS for c6678.

    Hi Zeki,

    I've asked someone on the MCSDK team to answer this.

    Hi Zeki,

    You can download the last release of Processor SDK RTOS (formerly known as SYS/BIOS) at:
    www.ti.com/.../processor-sdk-c667x
    and MCSDK 02_02_00_46 at:
    www.ti.com/.../demovideo-multicore
    but I note you that the last release is since 09/30/2015
    Therefore If you have experience with MCSDK should be useful to read MCSDK to Processor SDK Migration at:
    processors.wiki.ti.com/.../MCSDK_to_Processor_SDK_Migration
