Need help on ARM335x built with Linux kernel and RT-Preempt patch

Allyson Wu

Hello, All:

I am working on a project originally that used ARM3357 and Linux kernel without RT patch.  Because of application poor performance, I need try to build on Linux kernel with RT-Preempt patch.  The built didn't go smoothly.  

Can someone point me where I can get help online, or by any consulting company, or individual?  I need this project built on RT kernel as soon as possible.

Thank you

    Hi,

    TI already provides Linux SDK with the RT-Preempt patch integrated in the kernel:
    www.ti.com/.../PROCESSOR-SDK-AM335X

    Download and install PROCESSOR-SDK-LINUX-RT-AM335X. To build the kernel execute the following steps:
    cd ~/ti-processor-sdk-linux-am335x-evm-02.00.02.11/board-support/linux-4.1.18+gitAUTOINC+bbe8cfc1da-gbbe8cfc
    export ARCH=arm
    export CROSS_COMPILE=arm-linux-gnueabihf-
    export PATH=$PATH:<path/to>/ti-processor-sdk-linux-am335x-evm-02.00.02.11/linux-devkit/sysroots/x86_64-arago-linux/usr/bin
    make distclean
    make tisdk_am335x-evm_defconfig
    make -j4

    If you use some of the TI reference boards: am335x gp evm, am335x sk or am335x beaglebone black, you could use the prebuild binaries.

    "Can someone point me where I can get help online, or by any consulting company, or individual?"
    You could get support on this forum. You will need to share which SDK version are you using, and the log from your build.

    Best Regards,
