KW38 wireless-uart SDK can't create more then one task

[sihanchen]

Hello,

      I am working on the KW38 platform and use the wireless-uart example as my code base. I tried to create two tasks in my project, but it seems that only one task can be successfully created and run. I made an example as shown below and then tested it. I found that the priority of the TASK will determine which TASK will always be executed and another TASK will always be broken. I also tried to redefine FSL_OSA_BM_TIMER_CONFIG as FSL_OSA_BM_TIMER_SYSTICK to enable OS Timer and use OSA_TimeDelay(1000) to delay the running task so that another task can work, but it still doesn't work. Did I do something wrong?

Thank you.

Hi, 

Did you find any solution to this problem?

You need to increase the stack size. It is in the app_preinclude.h.

Hello,

      I can't find the stack size definition in app_preinclude.h (note: KW38 does not have FreeRots). I also referenced the app_preinclude.h of KW36 and found two definitions gMainThreadStackSize_c and gTotalHeapSize_c. But for KW38, only one stack size is defined as gMainThreadStackSize_c. I tried to extend this setting to 2048, but it still fails. Is there a more detailed explanation, Thank you.

Hi,

You are using bm example. So it is impossible to create the task. Please use the freertos example. 

Have a great day,
TIC

Hi, 

      As I mentioned before, the example code of KW38 does not provide FreeRTOS project, Could you please confirm again, Thanks.

Do you check if you click the 'freertos' when you download the sdk in 'https://mcuxpresso.nxp.com'
