标题: kernel_liteos_m移植到stm32h743xih6接管中断在内核初始化阶段的中断阶段发生异常
[md]kernel_liteos_m移植到stm32h743xih6使用不接管中断正常运行，使能 `LOSCFG_USE_SYSTEM_DEFINED_INTERRUPT` 1修改成接管中断的方式在内核初始化阶段的中断阶段发生异常，断点调试在 `LOS_KernelInit`函数154行 `ArchInit`函数里 `HalHwiInit`函数423行的 `NVIC_SetPriorityGrouping(OS_NVIC_AIRCR_PRIGROUP);`进入 `UsageFault_Handler`异常中断

控制台输出

1. ```
