自己简化一个myarmlib，用自己的

stm32是32位的，按32对齐访问，应该是内存访问越界 试试，捕获hard fault interrupt试试

嗯，下载下来学习一下！感谢！  

我想这个问题是针对，STM32F10x_StdPeriph_Lib_V3.5.0

@note - Low-density Value line devices are STM32F100xx microcontrollers where the    Flash memory density ranges between 16 and 32 Kbytes. - Low-density devices are STM32F101xx, STM32F102xx and STM32F103xx    microcontrollers where the Flash memory density ranges between 16 and 32 Kbytes. - Medium-density Value line devices are STM32F100xx microcontrollers where    the Flash memory density ranges between 32 and 128 Kbytes.   - Medium-density devices are STM32F101xx, STM32F102xx and STM32F103xx    microcontrollers where the Flash memory density ranges between 32 and 128 Kbytes. - High-density Value line devices are STM32F100xx microcontrollers where the    Flash memory density ranges between 256 and 512 Kbytes. - High-density devices are STM32F101xx and STM32F103xx microcontrollers where    the Flash memory density ranges between 256 and 512 Kbytes. - XL-density devices are STM32F101xx and STM32F103xx microcontrollers where    the Flash memory density ranges between 512 and 1024 Kbytes. - Connectivity line devices are STM32F105xx and STM32F107xx microcontrollers.
