很好奇你做的map表格哪里来的，自己做的？ 你看看F103系列Packet descriptor图明显就是按16位半字存放的，你怎么画成那个样子。 还有F1手册里明确描述如下： Packet Memory: This is the local memory that physically contains the Packet Buffers. It can be used by the Packet Buffer interface, which creates the data structure and can be accessed directly by the application software. The size of the Packet Memory is 512 bytes, structured as 256 words by 16 bits. 最后，何来浪费？
