"Hello world" is not output System_printf()

Intellectual 865 points

Hello,

I have created a simple DSP program, "hello world" message is not output.
Someone please tell me.

-----Development Environment-----

Code Composer Studio v5.2.1.00018
JTAG: SpectrumDigital XDS510USB Emulator
Board: UDWORKS DM8168DVR RDK
Platform: SYS/BIOS

----------------------------------------------

1.Create a new project.

2.Compile project.(template hello)

----- source code --------------------------------------------------------------

#include <stdio.h>
#include <xdc/std.h>

#include <xdc/runtime/System.h>
#include <ti/sysbios/BIOS.h>

/*
* ======== main ========
*/
Void main()
{ 
System_printf("hello world\n");

/*
* normal BIOS programs, would call BIOS_start() to enable interrupts
* and start the scheduler and kick BIOS into gear. But, this program
* is a simple sanity test and calls BIOS_exit() instead.
*/
BIOS_exit(0); /* terminates program and dumps SysMin output */
}
----- source code --------------------------------------------------------------
----- console ------------------------------------------------------------------

Why?

    Hideki,
    System_printf() is not quite the same as printf() from stdio.h. System_printf() can be configured to store the output in an internal buffer instead of sending it to the console. You can find out if System is configured that way from your CFG script. Somewhere in the CFG script you would have the statement that assigns System.ISupportProxy to SysMin, something like this:
    System.SupportProxy = SysMin;

    If you are indeed using SysMin, check this post to see how to read from the buffer using ROV or to flush the buffer to the console: http://e2e.ti.com/support/embedded/bios/f/355/p/84044/289714.aspx#289714.

    hello,

    Thank you for reply.

    The following code is already written
    System.SupportProxy = SysMin

    Listed as "No data to display" also OutputBuffer of ROV window.
    Preferences are basically wrong?

    Hi Hideki,

    Please try the gel file attached at the bottom of this post and let me know if it resolves the issue you are seeing.

    Hi Hideki,

    Did you power cycle the board or just reload the gel file in place of the other gel file?

    I think the issue that is happening has something to do with the way the gel file is setting up the memory.  Did a gel file come with the documentation and software that you got with the board?  Or is the only gel file you have the one that you downloaded from Spectrum Digital?

    Also, which "rev" of the spectrum digital gel file did you download and does it match the rev of you DM8168?

    Thanks,

    -Jon

    Hi Jon,

    Thank you for your reply.

    There was a mistake in my operation.
    I will report the results of the test again.

    "ti816x_ddr.gel" and "evm816x.gel" I have tried (spectrum digital), the result was the same.

    Regards,

    Hideki

    Hi Hideki,

    There are several different revisions of the "gel" file for the DM816x on the Spectrum Digital site.

    Rev. C,  Rev. C with DIMM, Rev. D and Rev E.

    Which revision of the gel file did you download and does it match the revision of the DM8168 chip on your board?  As a starting point, we need to make sure you are using the correct gel file for your board..

    Thanks,

    -Jon

    Hi Jon,

    Thank you for your reply.

    spectrum digital GEL file version is revE.

    But the board is made ​​UDWORKS.
    Dvr_netra.gel file is provided as part of the UDWORKS.
    Looking at the contents of this file,
      DDR3 769
    I was writing with.

    CPU revision is DM8168ACYG (rev1.1).

    Are there any other required information?

    6507.dvr_netra.gel

    8524.evm816x_revE.gel

    Regards,

    Hideki

    Hi Hideki,

    Please try the Dvr_netra.gel file that was shipped with the board from UDWORKS.    Let me know the results from using this gel file with your hello project.

    It's important that you use correct gel file.

    Thanks,

    -Jon

    Hi Jon,

    I tried dvr_netra.gel.

    I will report the results of running.

    6735.result.pdf

    In terms of results, "hello world" is output.

    I did with the additional
    -That it has made in the memory initialization scripts ( Scripts-NETRA External Memories-DDR3_796MHZ_doall )5633.dvr_netra.gel
    -That you have run main () in MoveToRun. "main()" function is not executed even if the Load Program.

    Hideki

    Hi Hideki,

    Looking at the result.pdf you posted it looks like your problem is solved, is this correct?
