System_printf() messages in Linux console

Other Parts Discussed in Thread: SYSBIOS

Hello,

I'm using SysLink. I run applications from command line in Angstrom distribution. I get there of course ARM side printf() messages. Is there any way to see System_printf() messages from SysBIOS application on DSP side? Or anything what is going on there on DSP? Without using CCS and JTAG emulator.

Best regards,

Valdez

    Hi Valdez,

    Unfortunately, we do not have support in SysLink for viewing the DSP side output on Linux. JTAG is the way to go in this case.

    Best regards,

    Vincent

    Hi Valdez

    In the UIA product, there is a module called LoggerSM. It is a logger that can be used with SYS/BIOS on the DSP. It places Log data (e.g. Log_print, Log_event, etc.) into shared memory. In linux, you can run a small utility that takes the contents out of the shared memory and either displays it to the console (if ASCII) or places it into a binary file that can be consumed by System Analyzer in CCS.

    There are some restrictions like

     - cache cannot be enabled for the shared memory that is being used for the log data

     - Need to specify the shared memory section as NOLOAD

    Please refer to the UIA User Guide for more details.

    Note: this is for Log data (e.g. Log_printN), not for System_printf.

    You can get UIA here: http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/uia/index.html
