AM5726: IPC questions

Janardan M
Expert 1115 points

Part Number: AM5726

Hi ,

I am working on Sitara AM5726 processor and developing a voice processing application, I want to access the DSP co-processor and perform some Audio signal processing operations on it. I refered the below wiki page to find how to add IPC to existing DSP SYS/BIOS project.

processors.wiki.ti.com/.../Linux_IPC_on_AM57xx

I added IPC to my existing DSP SYS/BIOS project using CCS 7.4, the binaries generated is with the extension ".out", but I found from the above wiki link that binaries with the extension ".xe66" is to be linked and added to the firmware folder of the master core (ARM A15) running on linux. So, is  binaries with extension ".out" and ".xe66" similar/same?

Also, is it possible to dump binaries to DSP C66x co-processor of sitara AM57XX using JTAG?

Can anyone please elaborate how to make the master core ARM A15 running on Linux to dump binaries to the co-processor  DSP C66x. (IPC is added to existing SYS/BIOS project and binary is generated using CCS).

I want to use AER voice support library on DSP C66x core of sitara AM57XX processor, I have found in latest AER release notes that AER is supported on below processors.

C55x/C64x+/C674x/Cortex-A8(TM)

So, since Sitara AM57XX has DSP C66x co-processor, does this core support AER library?

I am  new at using multi-core processors, so please guide me by clearing my bunch of doubts.

Thanks and Regards,

Janardan M

    Hi, Janardan,

    CCS builds .out for all processors. It is the same as .xe66, but .xe66 indicates for which processor it is for vs .xem4 for m4 processor.

    "Dump binaries to DSP cores", I think, you meant to download the binaries to the DSP? Please refer to the "Running the bundled IPC examples" in the same document you refer to. Rename your .out file to the file name remoteproc looks for. It will be downloaded by remoteproc during the boot time.

    I'll let the DSP expert to answer the AER questions.

    Hi, Janardan,

    I think the proper way of using the forum is one topic per thread. If you think your IPC questions are answered, please click "Resolved" button, and submit a new thread for AER question with correct subject line. Let's make this thread only to IPC.

    Thanks!
