Masking log_printf messages - it won't stop logging those log_print

Hi,

You need to set

var Main = xdc.useModule('xdc.runtime.Main');
Main.common$.diags_USER1 = Diags.RUNTIME_ON;
...

not Task.common$.diags_USER1. You were enabling/disabling the logging within the SYS/BIOS Task module, not your code. Each XDC module (e.g. Task, Swi, HeapMem, Memory) has it's own diags mask. Main is for all non-XDC code (e.g. your code). If you want a diags mask for each of your source files you can use the xdc.runtime.Registry module.

Just looked in your .cfg and realized you did have Main.common$.diags_USER1 = Diags.RUNTIME_ON.

Can you put "xdc_runtime_Main_Module__root__V.mask" into a watch window. Does it change as you are calling the Diags_setMask calls? (it should)

Take a look in the raw tab in ROV for the Main module. Can you post it? Here is one from an example that is working for me.

Hi Todd

Thanks for responding so quickly. I'm in a crunch to find this bug.

I put xdc_runtime_Main_Module__root__V.mask in my watch window and set a breakpoint at the first line of the code below

    if(0 == cnt)
    {
        Diags_setMask( "xdc.runtime.Main-1" );   // breakpoint here
        Diags_setMask( "xdc.runtime.Main-2" );
        Diags_setMask( "xdc.runtime.Main-3" );
        Diags_setMask( "xdc.runtime.Main-4" );
        Diags_setMask( "xdc.runtime.Main-5" );
        Diags_setMask( "xdc.runtime.Main-6" );
    }

Unfortunately, the watch variable did not change. Its stayed at 0x3F00 when I stepped through the code above between the { and }.

Below is my ROV. I noticed the Module_id is different.

Cheers

Thanks. There was a bug in the version of XDCtools you are using. Here is a link that describes the problem.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=333522

Can you set Text.isLoaded = true; in your .cfg and confirm this is the problem.

Eddie,
let's verify if the problem is in the config or in the runtime phase. Can you look in the directory Debug/configPkg/package/cfg in your project and find a large *.c file in there? Open it in the editor and search for "isLoaded". You should find the line:
__FAR__ const CT__xdc_runtime_Text_isLoaded xdc_runtime_Text_isLoaded__C = 1;
if the value is indeed 1, then the configuration set that parameter correctly and the problem is at runtime.

Can you also search for "xdc_runtime_Diags_dictElems" in that file? There should be a structure similar to this one:

xdc_runtime_Diags_DictElem xdc_runtime_Diags_dictElems[] = {
    {32779, &xdc_runtime_Main_Module__root__V.mask},
    {0, 0}
};

The important part is that the address of xdc_runtime_Main is in that structure. Also, the fact that you can find xdc_runtime_Main_Module__root__V.mask among the symbols in the executables indicates that the mask can be changed at runtime, otherwise we would not generate it.

I found a large ...p64P.c file in ...configuration\Default\configPkg\package\cfg. It was about 2 MB. The other .c files were less than 1KB.

It had

/* isLoaded__C */
__FAR__ const CT__xdc_runtime_Text_isLoaded xdc_runtime_Text_isLoaded__C = 0;

I could not find any "dictElems" in my file.

I checked to make sure I had this in my .cfg.

var Text = xdc.useModule('xdc.runtime.Text');
Text.isLoaded = true;

Strange eh!

Thanks for your help!

Cheers

I can't find any code in SYS/BIOS that would revert you 'isLoaded' setting. Can you add the following two lines at the very end of your CFG script:
print("isLoaded: " + Text.isLoaded);
Text.$seal("isLoaded");

The first instruction should confirm that 'isLoaded' is true at the end of your script, and the second instruction disables further changes and it will generate an error if some other code tries to change it. You should also set XDC_TRACE_ENABLE environment variable to "all" in the project properties, and then post the console output to this thread.

If 'isLoaded' is printed as 'false' at the end of your script, then the problem is in your script and you should be able by moving that print instruction up and down to figure out where in your script 'isLoaded' is turned to 'false'.

The variable XDC_TRACE_ENABLE is not one of my configuration variables. (the only "X" I have is XDCROOT). I take it you mean I should add this this as a variable. (via Project -> Properties -> Environment (tab) -> Project (tab) -> New)

I added the above code to my .cfg and do not see anything output on the console CIO window nor do I see anything in the print log window. Attached is the build log and the .cfg (I cleaned it up a bit from the previous one).

0005.XDC_TRACE_ENABLE.txt

Thanks a bunch for your help!

Hi Sasha

I try turning off the logs shortly. But here is the console output after I set isLoaded to true.

2555.XDC_TRACE_ENABLE_true.txt

2055.M2_EVM6472_true.cfg.txt

Cheers

Have you checked the generated C file? Is your original problem still present?

Hi

It appears to be working (and is it very helpful!). My apologies for somehow setting isLoaded to false. I have no idea how that happened.

What should I set XDC_TRACE_ENABLE to in order to turn off the console output. I'd like to keep it defined for future debug. Would "none" work?

Cheers

"none" would work. There are many more ways to filter trace messages. Here is the guide: http://rtsc.eclipse.org/docs-tip/Trace_Support.
