Hard fault: arm_dot_prod_q15() function ?

[jerrylian]

I am testing the following CMSIS-DSP function with MCUXpresso-IDE:

* arm_dot_prod_q15();

* The program finishes this function with correct result, but then goes to HardFault_Handler(), and never returns!

What could be wrong?

Thanks!

Jerry
