Posted on August 05, 2016 at 06:07This is an STM32CubeMX 4.16.0 generated project. The STM32CubeMX project file is attached. The processor is an STM32F373VCT6
I have a Hard Fault. Below is the call stack and register contents when the Hard Fault happened. It happens in STM32CubeMX generated code. I have suspicion it has something to do with TIM6, which is used to serve as the hardware ticker timer for FREERTOS. TIM6 was selected in an earlier version of STM32CubeMX. I no longer see where the hardware ticker timer is selected for FREERTOS. I only see that TIM6 is grayed out in Pinout tab.
This function is where it happened:
__STATIC_INLINE void NVIC_EnableIRQ(IRQn_Type IRQn)
{
NVIC->ISER[(((uint32_t)(int32_t)IRQn) >> 5UL)] = (uint32_t)(1UL << (((uint32_t)(int32_t)IRQn) & 0x1FUL));
}
Any help in fixing this would be appreciated.
