EOP的意思是操作完成的意思啊，手册上是这样描述的 The end of the program operation is indicated by the EOP bit in the FLASH_SR register.

不了解SWD原理，只是猜测 uint8_t swd_write_block(uint32_t address, uint8_t *data, uint32_t size) {         uint8_t tmp_in[4], req;         uint32_t size_in_words,size_send;         uint32_t i, ack,tmp;         if (size==0)                 return 0;         size_in_words = size/2;//计算半字数                        //size_in_words = size/4;         //计算字数         if (!swd_write_ap(AP_CSW, CSW_VALUE | CSW_SIZE16))//？？         {                 return 0;         }       // TAR write          req = SWD_REG_AP | SWD_REG_W | (1 << 2);         int2array(tmp_in, address, 2);                                //int2array(tmp_in, address, 4);     if (swd_transfer_retry(req, (uint32_t *)tmp_in) != 0x01)     {         return 0;     }     // DRW write     req = SWD_REG_AP | SWD_REG_W | (3 << 2);     for (i = 0; i < size_in_words; i++)     {                 if (swd_transfer_retry(req,  (uint32_t *)data) != 0x01)                 {                         return 0;                 }                 data+=2;//data+=4;     }        // dummy read     req = SWD_REG_DP | SWD_REG_R | SWD_REG_ADR(DP_RDBUFF);     ack = swd_transfer_retry(req, NULL);     return (ack == 0x01);          }
