MQX RTOS program always got stuck in "_mqx_idle_task"

[titusstalin]

HI All,

I'm working with FRDMK64F board.

Not able to debug and run any RTOS code on this board.

Always got stuck at "_mqx_idle_task" function.

It was working perfectly yesterday.

Just today I was soldered the board for for VIN line power up and did some RTC section.

I have two board with the same condition.

I hope it could be some hardware problem.

Please note that I'm able to run the "helloworld_k64f.bin" LED code on that problematic board.

Could any one help me to address this problem.

Any insights on this and it will be greatly appreciated?

Regards,

Titus S.

You will get stuck in _mqx_idle_task if BSPCFG_ENABLE_RTCDEV is defined to 1 and RTC is not functional or present.

[titusstalin]

Yes, you are right.

Thank you.

Even I'm not able to run "mbed_blinky" code which has size ~22KiB.

I'm able to run pre-build "HelloWorld_K64F.bin" which has ~14KiB size on board.

While debugging "hello_world_frdmk64f120m",always it get hang at the following line.

Its under MQS RTOS version "MQX_KSDK_1.0.0"

File : startup_MK64F12.S

Default_Handler:

Hi Titus,

Please download and try the latest KDS_2.0.0 and KSDK_1.1.0 to see if that resolves your problem.

Please list what debugger firmware interface you are using: PEMicro, Segger JLink, MBED ???  Maybe the firmware needs updating.

Regards,

David

Hi David,

Thanks for your reply.

I've tried KSDK_1.1.0 version too but with no success.

In that version, code always got stuck with "idle task" ie executing idle tasks.

I think, its a hardware problem.

I'm curious about this behavior, since I'm able to running LED blinking code which has size about 14KiB but not anyother code.

[DavidS]

Hi Titus,

When you enter Debug mode, are you step or look at memory?  Maybe more details of your steps will help me to help you.

When/if you are in the Debug mode, delete all breakpoints.  Sometimes "old" breakpoints cause issues.

Regards,

David

[titusstalin]

Thanks Dave.

I've tried already and no improvement.

Actually the problem seems either debug mode problem nor software problem but seems hardware issue.

Because the simple "hello world" program itself not working but as I told you  "HelloWorld_K64F.bin" this program is working good.

Also I suspect that any internal memory got corrupted since it was working with "HelloWorld_K64F.bin" which has just ~14KiB.

I have configured the board to "mbed" and copied the same binary which worked already and now it is not at all working.

I don't want to work with "DEBUG" mode but need "MBED" configuration.

Even I'm not able to run any "hello world" UART code and getting nothing output from USB"

[DavidS]

Hi Titus,

Zip and post your MBED hello world.

I just resurrected my frdm-k64 MBED board.  I updated the firmware (hold reset when you connect USB cable then drag firmware onto the BOOTLOADER MSD) and re-compiled an example project that prints out to the terminal (not MBED terminal should be 9600 and not 115200).

The Green LED blinks once a second.  I'll attach it as a ZIP too.

Regards,

David

[titusstalin]

Thanks Dave for your support.

I've updated the attached firmware (In fact I've tried already) and still facing the same problem.

One mysterious thing is the following "Hello world" program is working good (RED LED blinking)(~14KiB)

http://developer.mbed.org/platforms/frdm-k64f/#downloading-a-program

Also I build the following program and not working(~20KiB).

FRDM-K64F | mbed

"mbed_blinky_K64F.bin"

[DavidS]

Hi Titus,

I imported that code and it is working for me.  Sorry.

One last project for you to try to load.  It displays following on terminal:

Hello World!

0

1

2

3

4

.

.

.

Might be worth getting another board.

Regards,

David

[titusstalin]

Thanks Dave for your support.

Surprisingly its working (Green LED with UART o/p as you said) but not my latest project code which is worked already:-(

Also, not working which I rebuild binary through "MBED online compiler" and KDS (RTOS code)

Where did you get this code ?

It seems pre-built code.

I last :-(, I don't know whats going on my FRDMK64F board.

I've two boards with the same condition so I need to find out the root cause and solution.

Could you please help me.

[DavidS]

Hi Titus,

I'm just using my online MBED account to compile the project which then automagically downloads the binary for me to them drag-n-drop onto my MBED device (frdm-k64f freedom board).

The code is:

#include "mbed.h"

DigitalOut myled(LED_GREEN);

Serial pc(USBTX, USBRX);

int main() {

    int i = 0;

    pc.printf("\nHello World!\n");

    while (true) {

        wait(0.5);

        pc.printf("%d \n", i);

        i++;

        myled = !myled;

    }

}

Other things to try:

1) Use KDS_2.0.0 and KSDK_1.1.0 with attached frdm-k64 example code placed into the following folder:

C:\Freescale\KSDK_1.1.0

In KDS (after you did eclipse update for KSDK) and opened and compiled example, then using the Debug Configuration "OpenOCD" debugger interface to download and debug example.  Great reference for this and magic settings update is at: 

http://mcuoneclipse.com/2015/03/22/openocdcmsis-dap-debugging-with-eclipse-and-without-an-ide/

2) Use KSD/KSDK but load PEMicro debugger firmaware onto the frdm-k64 freedom board.  You have to get it from PEMicro.com

David

Hi Dave,

Thanks for your support.

Already I have tried to debug with "PEMicro debugger" and "JLINK" but no success.

I'm hang at "IDLE" task.

I'm curious that why its behaving like this since its worked past 3 months and suddenly stuck like this.

Could you please check that anyone have faced this sort of problem ?

Thanks again for your support.

[DavidS]

Hi Titus,

I tried Firefox and that worked for me.  Please make sure your terminal is 9600 for MBED.

For KDS/KSDK the baud is 115200.

Once in the Debug perspective, please remove/delete all breakpoints that are set.  Exit and re-download.

Attached is my example project to place into the C:\Freescale\KSDK_1.1.0 folder and import.  I forgot to attached in previous post.  Sorry.

Regards,

David

Hi David,

Thank you so much for your support.

Done, no progress.

I've removed the all break points and reloaded the code but no success.

[titusstalin]

Hi David,

Any other ideas or insights ?

I don't want to work with "Debug" mode as of now.

Just I want to put my serial code which is built through "MBED" online compiler.

Could you provide the example compiled on your machine (it could be better if example support for button,UART print and LED glow up etc.,)

So that I will try that example on my board and confirm that no HW issues and might have SW issue which need some sw upgrade etc.,

Thanks for your support.

[DavidS]

Hi Titus,

The attached MBED generated binary has UART baud set to 115200.

Press and hold SW2 or SW3 and the terminal output will indicate which SW was pressed.  Also the LED color changes.

With SW3, if you input a character, it will display the last 5 characters input (actually 6 but who's counting).

Use space bar to clear to clear that buffer.

Releasing the SW will also output the change.

Example terminal output:

Hello World from FRDM-K64F board.
SW2 released
SW3 released
SW2 pressed
SW2 released
SW3 pressed
Last 5 characters received were

FYI - to attach click on the "use advanced editor" link in upper right hand corner...then "Attach" link appears lower right corner.

Also attached is my MBED source.

Hi David,

Thanks for your support.

Given binary is working good.

I don't know that why the same code is not working if I built the code myself.

I have worked already and able to compile and run every thing okay.

I don't know whats going on :-(

As of now, I don't want to work with DEBUG mode and need to check that why its not working when I built via MBED online compiler.

Any ideas on this question ?

Thanks again.

[DavidS]

Hi Titus,

I'm running out of ideas.

I tried FireFox and Chrome and both browsers work for me.

Make sure your MBED account is setup correctly for FRDM-K64F.

You could try setting up a new MBED account as a test.

Sorry for your issues.

Regards,

David
