XScope Problems

[Redeye]

I'm trying to get XScope going on an AVB demo kit and it's just not working. So, I've gone back to basics with this code :

Code: Select all

#include "xscope.h"

int main()
{
	xscope_register(2,
	XSCOPE_CONTINUOUS , "Microphone Left", XSCOPE_UINT , "mV",
	XSCOPE_CONTINUOUS , "Microphone Right", XSCOPE_UINT , "mV" );
	
  while (1)
  {
    int sample;
    sample++;
    xscope_probe_data_pred(0, sample);
    sample++;
    xscope_probe_data_pred(1, sample);
  }
}

With the intention of trying to just prove it will create something. I've run it with :

xrun --xscope-file "test.xmt" --xscope-limit 1000 --verbose XscopeTest_Debug.xe

0x00010000 in main ()

Outputting xscope file test.xmt

but all it does is create an empty xmt file with this in it :

<XtEvents>
<XtEventTypes/>
<XtEventColors/>
<TotalXtEvents Number="0"/>
<XtEventRecords/>
</XtEvents>

Can anybody point me in the direction of whatever stupid mistake I'm making? The error suggests a problem with the .XN file, but I've done exactly what's specified in the tools manual so I'm confused.

Would you be able to attach the XN file you are using,

The message "First stage multi-node boot failed, please check XN file and Xmos link connectivity" is suggesting there is something not right with link configuration.

Matt,

Attached is the XN file (renamed as a TXT because it won't let me post with an XN extension!!). I thought I'd followed the instructions right, but I could be wrong.

[XMatt]

Could you change the XScope link from "XOLA" to "2" in the XN file and retry.

Exactly the same result :

Can you try this example which was used as part of the testing for the tools 11.11.0 release, it will verify that everything is connected correctly. Compile it with the XN you have and the command line.

xcc -o xscopetest.xe xscopetest.xc XR-AVB-LC-BRD.xn -lxscope

Code: Select all

#include <xscope.h>
#include <xs1.h>
#include <platform.h>
#include <stdio.h>

void xscope_user_init() {
   xscope_register(0, 0, "", 0, "");
}

void core0() {
  int i = 0;

  xscope_config_io(XSCOPE_IO_BASIC);

  for (i = 0; i < 10; i++) {
    printf("CORE 0 - Value of i = %d\n", i);
  }

  xscope_config_io(XSCOPE_IO_TIMED);

  for (i = 0; i < 10; i++) {
    printf("CORE 0 - Value of i = %d\n", i);
  }
}

void core1() {
  int i = 0;

  xscope_config_io(XSCOPE_IO_BASIC);

  for (i = 0; i < 10; i++) {
    printf("CORE 1 - Value of i = %d\n", i);
  }

  xscope_config_io(XSCOPE_IO_TIMED);

  for (i = 0; i < 10; i++) {
    printf("CORE 1 - Value of i = %d\n", i);
  }
}

int main (void) {
   par {
     on stdcore[0]: core0();
     on stdcore[1]: core1();
   }
   return 0;
}

Matt,

Ok I will have to investigate the other issue, im am suspecting that running a single core binary with xscope enabled (which is what you get without the multicore main) on a dual core device is producing the issue you are seeing. The example you have should give you a framework to start using xscope on your board. Let me know if there are any other issues. There are some examples here which may help https://github.com/xcore/sw_xscope_examples.

Matt,

I've just tried compiling and running this code :

Code: Select all

#include <xscope.h>
#include <xs1.h>
#include <platform.h>
#include <stdio.h>

void xscope_user_init()
{
	  xscope_register(2,
			XSCOPE_CONTINUOUS , "Microphone Left", XSCOPE_UINT , "mV",
			XSCOPE_CONTINUOUS , "Microphone Right", XSCOPE_UINT , "mV" );
}

void thread1()
{
	while(1)
	{
	    int sample;
	    sample++;
	    xscope_probe_data_pred(0, sample);
	}
}

void thread2()
{
	while(1)
	{
	    int sample;
	    sample++;
	    sample++;
	    xscope_probe_data_pred(1, sample);
	}
}

int main()
{
  par
  {
		on stdcore[0]: thread1();
		on stdcore[1]: thread2();
  }
}

Which compiles fine, but when I run :

xrun --xscope-file "test.xmt" --xscope-limit 1000 --verbose xscopetest.xe

it seems to hang xgdb - it goes totally unresponsive. This is similar to what I was seeing yesterday when I was trying to get XScope going - XDE kept hanging and then trying to melt my Macbook. It also seems very flaky at picking up the XTAG2 - sometimes it says it can't find a device even when it's just run fine. I'm beginning to wonder if it isn't the XTAG2. I've only just got this kit which was sent direct from Hong Kong to me.
