HardFault_Handler error with FreeRTOS, KL27

[gsmgbl]

Hi all,

I am using Kinetis KL27 and running a FreeRTOS 8.2.3 in it. In addition, I am using IAR Workbench for development. My ADC task was running fine previously, but I encountered a hardfault_handler error after I added a new task. But the error was not stuck in the new task, but the ADC reading task.

Anyway, it stucks at the "return pxList->uxNumberOfItems;" statement in the uxListRemove function in FreeRTOS.

I did some research about the hardfault handler, but i could not find any close to or related to my issue.

Please advise. In addition, please let me know what other information to provide more detail about this problem.

Thank you.

Gilbert

Hi Daniel,

I think I found what I did wrong in my program.

The hardfault is causing by my taskdelay in between enter and exit the critical section.

I should aware of doing this critical period short and clean, my hardfault_handler error is gone after I rearranged my process. Thank you for your time.

Regards,

Gilbert
