现象说明: 在 服务器端 与 开发板之间连接成功后, 就不会出现 任何错误,工作也都正常 当 服务器端断开连接后,大概 5-10s 左右就会出现 错误, 另外还会提示 Assertion "recvmbox must be deallocated before calling this function" failed at line 803 in ..\Middlewares\Third_Party\LwIP\src\api\api_msg.c Assertion "acceptmbox must be deallocated before calling this function" failed at line 806 in ..\Middlewares\Third_Party\LwIP\src\api\api_msg.c 请问 上面的 问题该如何解决啊 ?? 使用的是 embOS + Lwip 组合 |
