PROCESSOR-SDK-J784S4: linux-rt performance guide / cyclictest results

Part Number: PROCESSOR-SDK-J784S4

Tool/software:

Hi

I've found cyclictest results for the AM64X variant here:

https://software-dl.ti.com/processor-sdk-linux-rt/esd/AM64X/latest/exports/docs/devices/AM64X/linux/RT_Linux_Performance_Guide.html?highlight=cyclictest#stress-ng-and-cyclic-test

Is this also available for the J784s4?

Regards

Daniel

    Daniel,

    We do not have the rt-linux SDK for j784s4.

    We only have Linux/RTOS/QNX:

    So we do not have numbers for rt-linux.

    Best Regards,
    Keerthy

    Hi Keerthy

    OK. This means the SoC and/or the SDK is not realtime capable?

    We are not using the SDK directly but cloning the Git repository and using the Linux kernel "-rt" branch. If this is not realtime capable - why is it here?

    Regards

    Daniel

    Hi Daniel,

    SoC is capable. SDK we do not have the rt-Linux version.

    This could be used for real time capability. I checked internally that rt- branch can be used on j784s4.
