using log module in sysBios with my own host processor

Other Parts Discussed in Thread: SYSBIOS, TMS320C6746, TMS320C6424

We are thinking of using sysBios on our new C6476 based product. It is essentially host processor (arm or ppc) talking to dsp farm.

I am looking at possibility of logging the dsp event/info to host processor. In sysBioss, there is a logging module, but it seems to be only usable to talk through jtag with CCS, if I understand correctly. Is there a way that I can use this module to pass the log entries to my host processor through the log buffer? Is there example programs for this if this is possible at all?

 

thanks

    Weichun,

    Can you confirm the device number again. I can`t find the device that you have mentioned on the TI website?

    Also since this is SYSBIOS specific question, it might be better answered on that forum rather than the device forum so I am moving this to the BIOS forum.

    Regards,

    Hi, Rahul,

     

    thanks a lot. It was either TMS320C6746 (http://www.ti.com/product/tms320c6746?qgpn=tms320c6746) or TMS320c6424 (http://www.ti.com/product/tms320c6424?qgpn=tms320c6424-500).

     

    thanks

    We are working on non-JTAG solution for transferring the log data to the host.    But, we don't currently have a solution for the devices you mention and no firm plans for when we will.   We have such support for the multicore devices (667x) and TI816x devices coming in CCSv5.1.

    Thank you so much Karl.

    is there a detailed interface document so that we can use the DSPBios and implement the host side of interface ourselves? I assume that it would be some shared memory, we just need to add some synchronization hooks then we can use the same buffer/data to talk with either jtag or other host, right?

    any document, ideas in that direction?

     

    thanks

    If you have the NDK (TCP/IP stack) then the UIA solution might be a good one for you.  I just built and ran this no my evm6748 board using CCSv5.1 beta2.

    You can read more about UIA in the docs attached here:

    http://processors.wiki.ti.com/images/b/b5/MCSA_User_Guide.pdf

    You can download latest UIA release here:

    http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/uia/index.html

    We do not have any docs yet on how to add new transports.
