Can't display cpu usage or timeline

    I'm using a K60FX512 MCU with MQX4.0 and CW10.4. I have created klog in my program. And I can see 'Performace data view' and 'stack usage'. But when I tried to open timeline, It tells me that 'no task switches found'. In cpu usage it shows nothing.

   I've tried both online and offline mode. Neither of them worked.

   I've used this in my last project which is on MQX3.8. And it just worked well. I don't know what's the difference.

Hi Yang,

Since you already saw it working on MQX 3.8 I will assume you already added these two lines in the user_config.h file:

#define MQX_USE_LOGS                         1
#define MQX_KERNEL_LOGGING                   1

Make sure you recompiled PSP and BSP again after this change.

If so, then you need to check the example code I am attaching which I already tested and is showing with context switch timeline.


Regards,
Garabo

Hi Yang,

Yes, your file looks fine. It should be another problem. Could you please add a break point in the dispatch.S file just in the line where the context switch is being logged into the kernel log? Just in the same line like the screen shoot shows:

pastedImage_0.png

Once you reach that break point go and take a look to your KLOG in the task aware debugging (MQX menu)

Hope that helps to find what is the issue.

Garabo

Have the same issue here. Activated both macros in the user_config.h file, recompiled and however can't even access kernel log via the MQX menu (as said in your reply). Can access, however, Stack Usage. CPU Usage View is also not working.

Using FRDM-K64F + MQX RTOS 4.1 + CW 10.6.

Thank you!

Hi Luiz,

I just tested with a few modifications to the previous code and adding a break point in the line 119. I am able to see the context switching and the CPU usage with no issues. I am attaching the new code tested in MQX 4.1 for FRDM-K64

I've tried klog.c. It didn't work. The result is just the same as my own program.
