> hard fault. I think it because of NULL pointer exception Insted of thinking, put an assertion to verify that, and follow your processor debugging instructions to understand the actual reason of the hard fault. Even your OS has a guide on that: http://www.freertos.org/Debugging-Hard-Faults-On-Cortex-M-Microcontrollers.htmlPS: I would honor and follow advice regarding memory allocation functions, if I was you and I was chasing a fault on some error that depends on the number of data being processed.
