MIMXRT1170-EVK FreeRTOS Hello Example Issue

Rosh — Fri, 07 Aug 2026 09:05:48 GMT

Hi Team,

I imported the evkbmimxrt1170_freertos_hello_cm7 example project from the MCUXpresso SDK into MCUXpresso IDE without making any significant modifications.

The project builds successfully without any errors or warnings and downloads to the MIMXRT1170-EVK(MIMXRT1176DVMAA) board successfully.

The task created successfully and executes only once and then stops at address 0xDEADBEEE. This behavior occurs every time.

LED Toggle Task:

To verify whether the problem was related to vTaskSuspend(), I've created another task with a simple LED blinking task.

Expected behavior:

LED should toggle every 100 ms continuously.

Actual behavior:

LED toggles only once.
After the first execution, debugger again stops at: 0xDEADBEEE

Kindly clarify the following queries,

What does address 0xDEADBEEE indicate in the MCUXpresso SDK for i.MX RT1170?
Why does the task execute only once instead of running periodically?
Is there any additional configuration required to work correctly on the MIMXRT1170-EVK?
What changes are required to make the task execute periodically as expected?

Hello @Rosh,
I understand that you are currently using the MIMXRT1170-EVK. Please note that the SDK for the MIMXRT1170-EVK is different from the SDK provided for the MIMXRT1170-EVKB. Could you please download and test with the SDK specifically generated for the RT1170-EVK using the MCUXpresso SDK Builder?

I understand your point. The SDK examples are intended to provide a common use cases for each peripheral functionality. The 0xDEADBEE value is typically associated with a HardFault condition.
Could you please run the example without any modifications and let me know the results using the latest available SDK version?

Habib

Hi @Habib_MS

I've downloaded the SDK specifically generated for the RT1170-EVK using the MCUXpresso SDK Builder and tested it. It is working fine now.

Thank you for your support.
