Hi everyone,

Current I use omap l138, it has chipint can use for arm and dsp for notify.

I survey new platform keystone. It has mailbox for the purpose.

So keystone has no chipint for notify arm and dsp.

Is it right?

    Hi,

    Yes. Based on boot mode user can able to boot DSP and ARM core separately. For more information refer keystone data manual and bootloader user guide.

    Thanks,

    Hi descent,

    The information you provided is not sufficient for us to guide you. Or may be your question is very narrowed one.

    Is it keystone I or Keystone -II?

    To know more about mailbox on keystone platforms, please visit TI WIKI:

    Hi Shankari G,

    Thank you for your information.
    I need write code for arm core and dsp nodify by myself, and don't use ipc 3.x framework.
    So I reference linux_src/driver/mailbox for the arm side mail.
    I am not familiar c6000 dsp and toolchain, but I want to reference ipc 3.x code.
    Is the right way?

    Hi descent,

    To get familiar about where to start, I have attached a ppt.

    For Keystone - II

    ===============

    For ARM side, please refer to the user guide "IPC_Install_Guide_Linux.pdf " which is given under" \MCSDK_3_15\ipc_3_00_04_29\docs"

    For DSP side, detailed instructions on how to install and build the DSP-BIOS version of IPC are in the file IPC_Install_Guide_BIOS.pdf that is part of the release in directory \MCSDK_3_15\ipc_3_00_04_29\docs.

    Go through the docs and let us know how it goes and what you learn.

    Please feel free to revert back if you have questions.
