Hard fault: arm_dot_prod_q15() function ?

jerrylian — Thu, 25 May 2017 21:18:39 GMT

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

I hope this helps.

Hi, Robin:

Thanks for your information, but I solved my problem with the following post:
