Log_info form Float number format

I believe this should work.

To support the floating point %f conversion characters, you must add this to your config script:

var System = xdc.useModule('xdc.runtime.System');
System.extendedFormats += "%f";

I hope this works for you.

Hi Alan, these additional strings, permit to use Log_info("%f");?

i've tryed

but the Log_info1("prova float %f",(float 1.5); produce the string "prova float %f" on the screen.

Sure that this works with Log_info()?

Fabio

Fabio,

This should work. I can't even get Log_print1() to work either. I'll check into it and report back ASAP.

Alan

Fabio,

I was misinterpreting my results. When I flushed the logs to the console, both Log_info1() and Log_print1() prints were as expected.

Here are my .cfg file settings:

  var System = xdc.useModule('xdc.runtime.System');
  System.extendedFormats += "%f";
  var LoggerBuf = xdc.useModule('xdc.runtime.LoggerBuf');
  var Diags = xdc.useModule('xdc.runtime.Diags');
  var Defaults = xdc.useModule('xdc.runtime.Defaults');
  var Main = xdc.useModule('xdc.runtime.Main');


  // Configure LoggerBuf to flush logs
  LoggerBuf.enableFlush = true;

  // Create default logger for the whole system.
  var LoggerBufParams = new LoggerBuf.Params();
  LoggerBufParams.exitFlush = true;
  Defaults.common$.logger = LoggerBuf.create(LoggerBufParams);

  // Turn on Info logs in Main module (all non-modules)
  Main.common$.diags_INFO = Diags.RUNTIME_ON;

Here are my Log_info1() and Log_print1() call sites in the C code:

  Log_info1("Hello %f", floatToArg(129.72));
  Log_print1(Diags_INFO, "Hello %f", floatToArg(129.72));

And here are the resulting console outputs:

  #0000000002 [t=0x0000d9f3] xdc.runtime.Main: "FloatTest1.c", line 163: Hello 129.7200
  #0000000003 [t=0x0000db6b] xdc.runtime.Main: Hello 129.7200

Hi Alan, 

thanks for your indications. 

So i try it, but i use UIA and then a must use the LoggingSetup in order to configure the System Analyzer, end point, etc.

So this is my .cfg:

var System = xdc.useModule('xdc.runtime.System');
var BIOS = xdc.useModule('ti.sysbios.BIOS');
var Log = xdc.useModule('xdc.runtime.Log');
var LoggingSetup = xdc.useModule('ti.uia.sysbios.LoggingSetup');
System.extendedFormats += "%f";
var Diags = xdc.useModule('xdc.runtime.Diags');
var Defaults = xdc.useModule('xdc.runtime.Defaults');
var Main = xdc.useModule('xdc.runtime.Main');
var Task = xdc.useModule('ti.sysbios.knl.Task');

var taskInitParams = new Task.Params();
taskInitParams.instance.name = "taskInit";
taskInitParams.priority = 15;
taskInitParams.stackSize = 32768;
Program.global.taskInit = Task.create("&taskBootUpFnx", taskInitParams);

// Turn on Info logs in Main module (all non-modules)
Main.common$.diags_INFO = Diags.RUNTIME_ON;
BIOS.libType = BIOS.LibType_Instrumented;
LoggingSetup.eventUploadMode = LoggingSetup.UploadMode_JTAGRUNMODE;

and when i use 

Log_info1(" Log_info1 Hello %f", floatToArg(129.72));

the result is  Log_info1 Hello %f". And The same for Log_print.

So without LoggingSetup how i can see the Log_info Result that you have try? You use Uia in Debugger?

Can you give me some indications?

Thanks

Fabio

Good morning,

is there someone that can support me to use Log_info for float (%f) number using UIA Logging? with CCS and DSP C6457?.

Thanks in advance.

Fabio

Hi Janet,

This looks like a bug in System Analyser (the floating point support works in XDC logger, but not for UIA, which is supposed to be superior).

Is there any plan to fix it?

In any case, many thanks for the proposed workaround.

Regards,
Vasili

Hi Vasili,

Which XDC logger are you referring too?  Are you viewing it with ROV or System Analyzer?

Thanks,

    Janet

Hi Janet,

My setup is:

CCS 6.0.0.00190
XDCtools 3.25.05.94
BIOS 6.37.02.27
UIA 1.04.00.06

The project uses UIA:

var System = xdc.useModule('xdc.runtime.System');
var LoggingSetup = xdc.useModule('ti.uia.sysbios.LoggingSetup');
var LogSnapshot = xdc.useModule('ti.uia.runtime.LogSnapshot');
System.extendedFormats += "%f";

And in CCS I use "Tools->RTOS Analyser->Printf and Error Logs" which opens a "Live Session" pane. AFAIU, it is part System Analyser, right?

In this pane I see "%f" where I would expect the floating point numbers (for comparison, integer work fine).

As you can see in Alan's post above, the floating number printing works fine for him when using:

var LoggerBuf = xdc.useModule('xdc.runtime.LoggerBuf');

Best,
Vasili

Hi Vasili,

What target are you using?  I found that this did not work with C28 floating point, although for M4F it worked fine.  When running on a Piccolo F28069 control stick, I got this output in System Analyzer:

The address of the string was correct, but for some reason it didn't display it.  Was this the sort of failure you are seeing?

Best regards,

    Janet

Hi Janet,

My apologies for the late answer, i was away for some time...

I'm using somehow customized A8 target with gcc compiler. But I doubt that my customizations can be the cause for the problem here.

Here is how I see in "Live section" pane:

Best,
Vasili

Hi Vasili,

I doubt also that this has anything to do with the A8 and gcc compiler.  Are you seeing the Snapshot event in the Live Session window?  This is what I see:

I'm also attaching the test that I generated the output with:

5543.logSnapshotFloat.c

8463.logSnapshotFloat.cfg

Best regards,

Hi Janet,

I'm failing to build your code. Getting the following error:

generating interfaces for package configPkg (because package/package.xdc.inc is older than package.xdc) ...
  configuring logSnapshotFloat.x from package/cfg/logSnapshotFloat_p.cfg ...
  js: "D:/Dev/trunk/Src/Firmware/Sitara/Products/logSnapshotFloat/logSnapshotFloat.cfg", line 130: XDC runtime error: ti.uia.sysbios.LoggingSetup: no element named 'snapshotLogging'
      "./package/cfg/logSnapshotFloat_p.cfg", line 184
  gmake.exe: *** [package/cfg/logSnapshotFloat_p.xdl] Error 1

Maybe I shall update UIA or something?

Best,
Vasili

Hi Vasili,

The .cfg file I posted was from a test I made for UIA 2.0.  To get this to build for UIA 1.04, you should be able to just remove the line:

LoggingSetup.snapshotLogging = true;

from the .cfg file.

Best regards,

    Janet

Hi Janet,

I've updated my tools to the latest available versions and succeeded in running your example on A8 target.

xdctools_3_30_04_52
bios_6_40_03_39
uia_2_00_01_34
CCS 6.0.1.00040

The output I see matches what you've seen (as posted above). Namely:

1. Log_print1 with %d argument works fine (as expected).
2. Using intermediate string buffer works fine:
   1. Print floating number using System_sprintf with %f argument
   2. Save buffer using LogSnapshot_writeString
   3. Use Log_print1 with %s argument
3. However, Log_print1 with %f argument does not work. CCS just shows %f as you can see in your screenshot.

Of course, (2) provides a workaround, but does TI plan on fixing (3)?

Best regards,
Vasili

Janet?

Hi Vasili,

Sorry I missed this one!  I'm not sure when/if this will be available in CCS, but I'm still waiting to hear back on this.  In the meantime, maybe you could post this question to the CCS forum.

Thanks,

    Janet
