/**
* @brief This function configures the source of the time base:
* The time source is configured to have 1ms time base with a dedicated
* Tick interrupt priority.
* @note This function is called automatically at the beginning of program after
* reset by HAL_Init() or at any time when clock is reconfigured by HAL_RCC_ClockConfig().
* @note In the default implementation, SysTick timer is the source of time base.
* It is used to generate interrupts at regular time intervals.
* Care must be taken if HAL_Delay() is called from a peripheral ISR process,
* The SysTick interrupt must have higher priority (numerically lower)
* than the peripheral interrupt. Otherwise the caller ISR process will be blocked.
* The function is declared as __weak to be overwritten in case of other
* implementation in user file.
* @param TickPriority: Tick interrupt priority.
* @retval HAL status

测试发现如果注释掉这段代码就正常了：

对应对应结构体：

{
float offset_inner; //内圈偏移值
float gain_inner; //内圈增益
};
struct channel_parameter_outer
{
float offset_outer; //外圈偏移值
float gain_outer; //外圈增益
};
struct graycode_encoder
{
struct channel_parameter_inner chan_param_inner[6];
struct channel_parameter_outer chan_param_outer[6];
float channel_val_inner[6];
float channel_val_outer[6];
float cali_factor[168][6];

uint16_t rough_section;
float angle;
float Absolute_Angle;
float Set_CurrentPositionAngle_0;
enum calibration_state Cali_flag;
}__attribute__((aligned(4))); // 强制4字节对齐
有大佬遇到过类似问题么，求解惑
