在HarmonyOS鸿蒙Next中移植STM32F4并使用lite-m时，若log输出Exception Information信息，可能是由于以下原因：

  1. 内存配置问题：检查liteos_m/config.mk中的内存配置，确保LOSCFG_SYS_EXC_INFO已启用，并正确配置了LOSCFG_PLATFORM_EXC。

  2. 中断配置错误：确保中断向量表正确配置，特别是HardFault、MemManage等异常处理函数。

  3. 栈溢出：检查任务栈大小，确保足够大以避免栈溢出。

  4. 硬件问题：检查硬件连接，确保STM32F4的时钟、电源等配置正确。

建议逐步排查以上问题，确保系统配置与硬件匹配。
