OMAPL137 DSP running with ARM Linux

Hi !

I've got the OMAL-L137 EMV from Spectrum Digital...

I've also got some nice running in Emulation mode through CCS. This code is intended to run on the DSP and I do not yet explicitly do anything with the Arm...

Does this mean I can generate an AIS with AISgen from the .out file and simply flash that ? Do I have to indicate to the Dev Board whether it has been flashed it to NAND or SPI ?

Also, what changes about this process if I want to use the ARM running Linux to read from the SSD card and send that information to the DSP ?

Thanks,
Amanda

    Hi Amanda,
    I have split your post from old thread since newer posts would get much attention so, when ever you have problem/question, click "New" button the particular forum to create a new post.

    Able to boot Linux in OMAPL137 ?
    If not, you may need DSP UBL,ARM UBL,u-boot,Kernel and filesystem.
    DSP UBL is to wake up the ARM core and ARM UBL code is to initialize the DDR to run u-boot code, u-boot would initialize the other peripherals and copy the kernel into RAM & execute.

    If you want to run DSP app with ARM linux, then you may need IPC mechanism to communicate between cores.
    We used to communicate between cores through DSPLINK/SYSLINK software.

    You can refer to the following TI wikis and E2E posts.
