KSDK 1.1.0 and KDS 2.0

[a8Chcx]

Hi Alice,

When I am using KSDK1.1.0 and KDS 2.0 to generate KSDK+PE project. I had the same problem as JunFeng.

But, if Iuse KSDK1.0.0, it is fine...

Could you let me know if you have the solution for that?

Thanks,

Christie

Hi Christie,

We only need select the MQX_KSDK under the "fsl_os_abstraction" component. Needn't add the mqx_ksdk component.

About the detail I have show on there :

Hi Alice,

It is fine for building...

But, when I do the debugging, the following error happened

Could you tell me how to fix this problem?

Thanks,

Hi Alice,

I created the exact same project as that you propose to JunFeng. When I debug the code, I got the above error message. See attached file.

Hi Alice,

I just created very simple KSD+PE project. Then I choose MQX for my project. All other just fix the error in project...

The problem is easily duplicated.

If I choose the standard for MQX instead of Lite(default setting), it works fine.

So, I can't use MQX lite for this option?

Thanks,

Christie

Hi Alice,

I can do the same as what you did without any problem.

The problem happened after you create a task. Then you will see the error on HyperTerminal.

But, if I configure MQX to Standard instead of Lite(Default) and re-configure the debug UART as required, it start working. See attached for re-configuration.

Thanks,

Christie

Hi Christie,

Could you  send the project which have error when debug to us ?

Hi Alice,

Please check the attached project that I just created. You will see the error message on HyperTerminal. If you change MQX to Standard and re-configure UART, the error message will go away...

Please let me know what you find?

Thanks,

Hi Su,

This is really a problem , sorry for the inconvenience for you !

Now my colleague DavidS  come up with work around :    What's mean - assertion "!status" failed: file "C:/Freescale/KSDK_1.1

"

Workaround:

1) Set the OS_Task priority between 0 and 9. 

     fsl_os_abstraction_mqx.c adds "7" to the priority you set in the component so as to reserve 0-7 for MQXLite OS.

     Later in task.c there is code to check the priority of the task as compared to LOWEST_TASK_PRIORITY which is set to default to 16 decimal.

2) change the LOWEST_TASK_PRIORITY 40 and the default OS_Task priority of 32 will work.

"

Hope it helps

Hi Chrristie,

Sorry to reply you late !

And i have test on my side ,it is same like yours.

I think this it doesn't matter,  you can test a simple demo on the task .

while i will ask the KSDK team what meaning about this, and will tell you the result .

Thank for your support to freescale !
